Contemplating using N7 as car head unit/nav system - Nexus 7 Q&A, Help & Troubleshooting

As the title says I am very interested in using this tablet as a head unit replacement. I still have plenty of researching to do, but before I get too deep into it, I think there is one problem that should be addressed.
I wouldn't consider myself an audiophile, but I do like my music. So using the 3.5mm jack for audio simply will not do. I have seen a video of someone using a Turtle Beach audio adapter to get usb audio out of the N7, and then into the stereo/processing unit. This would be perfect for me, however I also need to be able to hook up an external drive for additional storage.
So my question is if it is possible to hook up the usb audio cable, and an external drive simultaneously to the N7. My idea right now is to hook up an OTG cable to the N7, then plug in a small non powered usb hub which would have both the external drive and usb audio cable hooked up to it. I am just not sure if this setup is possible, and before I purchase all the components I would like to have some confirmation that it will work like i think it will.( I will be using a rooted N7 with stickmount installed, I believe that is all I need to allow Host capabilities)
On a side note, I also plan to use the pogo pins to charge the device. I saw a video of someone using a hacked usb cable to charge the galaxy nexus with it, so i think that should work. (I just read a thread saying that the galaxy nexus can't charge through a pogo pin dock while having a OTG cable plugged...My dreams are being crushed.)
If you would like any more info about the specifics of the setup, I would be happy to share my ideas.
Sorry for the length of the post, I just want it to be clear what I am trying to do here.
Any information, or tips would be greatly appreciated.
Thank you.

I think my dreams are also crushed, I believe the pogo pins are a pin-out extension of the usb port, not a separate port, therefore using OTG would ****-block charging, which is disappointing.
You could however use one of these in your car http://www.slashgear.com/seagate-goflex-satellite-wi-fi-hard-drive-gets-android-app-01168797/ which would provide 500GB of storage accessible whilst your nexus 7 is charging, combine that and a pocketwifi device to act as a router and provide internet access it would be perfect
if you had an AC power inverter or appropriate power supply for DC to the unit (saves inverting then converting again), you could use this one http://www.ccpu.com.au/show_prod.php?class_id=disk-ext&prod_id=STAM1000200

would be very awesome, looking forward to updates.

Thanks for the info.
That is deeply saddening that you can not use both at the same time, although I guess it does make sense for the purposes of a dock. So it looks like now the only way I can still use a plugged in external hdd, usb audio, and be able to charge the device at the same time is if I can do all of that through the mini usb port in conjunction with a usb hub...but i think that is unlikely. does anyone know for sure?
And thank you for bringing up those wifi hard drives. I didn't want to use them, something about having it plugged into the device directly just makes me feel better...although now I will have to seriously consider them.
Also, if anyone has any info regarding tablet install you think may be useful, feel free to post the link. Even if it is not directly related to the N7, it could still be useful info, and maybe get some gears turning in our heads.
I just became a member so I am not allowed to post links yet :silly:
I will still keep my hopes up about using this device, though! It is my favorite 7 inch tablet by far.

What about usb powered hubs?

Can the Nexus output digital audio, charge, and read an external HDD, via powered usb hub from its one micro usb port? If it could then all my problems would be solved! Until I encounter my next problem, of course. :silly:

Sounds very interesting indeed. I look forward to seeing what can be done.

Nope. Did not work for me.
I thought about using the Nexus 7 as my car nav system as well. I stumbled across an issue where I want to mount external USB drive AND charge the tablet at the same time. I could not get the tablet to charge with a powered USB drive. I believe the tablet is going into host mode to read the USB drive, and thus disallowing any kind of power to charge itself.
Please someone prove me wrong.. I really like this tablet. It is the perfect size for the car.
Another issue I found... Using polarized sunglasses + nexus 7 (landscape mode) = completely black screen. This may or may not convince you to continue with this project. I am certainly looking at different options..

Im thinkin about this too. But not to completly replace my headunit but only to slap it on for long drives

I noticed this, too. Disappointing. My HTC EVO View works fine, though.

Very interested in this. I've actually been working on this very project. I'm near completion (sort of) actually, but I'm having a separate electrical issue currently so its been on hold for the last week or so. At this point I've run sound via the 3.5 mm jack, but if a USB solution is found, I'd be all over that. I guess I settled for the 3.5 mm jack as previously, I tended to stream Pandora and various music through the aux jack on my phone anyways. Probably more than 90% of the time actually. I may look into the Seagate GoFlex Satellite WiFi HDD for external storage since charging and USB OTG at the sime time at this point seems impossible/difficult. I have a pair of polarized oakleys that i usually wear, and havent noticed the screen blacking out yet, but I'll have to see when I get home tonight.

On charging & usb host mode at the same time..
Has anybody tried this:
1. Setup a powered USB hub plugged into the Micro OTG cable
2. hack the cable from right after the OTG cable to where it plugs into the hub, so that the voltage pins are exposed
3. solder in the voltage pins to a usb connector so you can plug in a normal charger [5V 2A]
4. check to see if you can use the USB hub and charge at the same time
I currently have a Asus transformer TF101 and the primary use is watching clips off a 500GB usb HDD. I really, really want to get a N7 and sell my TF101, but if charging & simultaneous host mode is not possible, I would be slightly hesitant to buy it, even though it is really a awesome tablet from what I hear.
so if anyone has any info on that, I would greatly appreciate it!

I know a lot of people that the 3.5 mm jack for audio. And It really does sound just fine. It is just that I am planing on investing a lot in amps/speakers, so I don't want my weakest link to be my inputs right out of the gate. Although, this tablet is making it pretty difficult to not use that jack.
I would be interested to see your project whenever you finish, or if you have information up of of the process now, that would be interesting to look at.
Thanks again everyone for all the info! I still have a shred of hope for using this tablet in my car!

I'm running 4 Polk 6" speakers that replaced the stock ones in my car (just replaced them all last year when I blew one of the stock ones), and a cadence 4 channel amp to power the speakers. Nothing top of the line, and no subwoofer or anything as of yet. Picked up the cabling from monoprice, with all of it being their "premium" selection. It all seems pretty heavy duty and solid. Only ran me around 30 bucks. I just have an 02 Mitsubishi Lancer that I'm putting this in. The dash is originally a single din so it's taken quite a bit of modification to get it to fit. More than I originally anticipated. Just a hobby project I've wanted to do for sometime and when the nexus 7 came along I jumped on it. I'll post some pics when I have a chance but at this point it looks far from professional. lol.
Also, I pulled out the Nexus 7 last night and had my polarized glasses on, no screen blackening that was mentioned previously for me. Maybe a little distortion/filter over the screen at certain angles, but still viewable.
I think this thread is great. I'd love to see/hear what other people are doing or what ideas come about from this.

Thank you, I am really glad this thread has spiked some interest, and that other people have similar ideas. I will start up my research again and come back to post any new info when I can. Gotta keep this thread going strong!

I created a thread with the few pictures I took along the way, as well as the semi-finished project. The only thing I believe I still need to do at this point is get a screen protector. (Tablet still has the plastic cover on it from when it was in the box!) Other things may come up in the future, (such as adding an OTG cable if someone figures out a way to charge simultaneously) but this is it finished for the time being.
http://forum.xda-developers.com/showthread.php?p=29824916#post29824916

Thanks for making a thread! That is very cool, I like your setup a lot. Is the tablet meant to stay in the car permanently, or do you plan on taking it out often?

Alright, I haven't had much time to find much new information. But I was just thinking if I can't have it charge from the usb port and run usb audio out at the same time, then maybe I could take off the rear cover of the N7 and cut a hole in it, where the camera was supposed to go, and route positive an negative wires directly to the battery...then I could use a hacked usb cable to charge it...? Just the thought of that is scary, but I don't plan on taking out the N7 ever, it will always stay in the car.
Just a thought, let me know what you think.
Additional info: I am going to be putting this in an 02 e46 BMW 325xi. And I will use a modified double din face plate. In my head the final setup looks beautiful, but we'll see how it turns out. As for the time frame, I have a list of parts I want to get for the car, and I want to do most everything at the same time. It will take a good 3 or 4 months before I can get everything and then installing it might take another month(assuming everything goes smoothly) I just want to get all of my preliminary research out of the way. Sorry if you guys were expecting pictures soon.
Thanks

What about the pogo pins? Aren't they for a [future] dock? I wonder if you can charge the tablet via the pogo pins and use USB OTG simultaneously? This would indeed be good news, because I will primarily use my N7 [when it arrives] for videos on a USB HDD, so it would wear out the battery to be constantly charging and discharging the battery every day.

Earlier in the thread we had thought of that, turns out you can only use one at a time, and it's a hardware limitation so no way around it.

MKV Jetta 2013 Nexus 7 Install - work in progress

Hey everyone. I have been working on an in-dash Nexus 7 install in my 2010 Jetta Wolfsburg, and I thought I would share my progress as I go in case any one else was considering this for their car. I did a similar install with the original Samsung Galaxy Tab in my 1998 BMW 540i which can be seen on bimmerforums if you're interested. Just search E39 Android Tablet Install.
The first think I did was to buy a double din kit from Metra for about $12 from ebay. I took a Dremel to this and modified it by cutting off the center piece as well as all 4 clips on the corners. Then I got some Plastic Weld made by JB weld from Home Depot and started to shape the bezel like I wanted it to be for the Nexus 7. To get this to be flat and mate with the tablet nicely, I had to take a nail file and sandpaper and fill/sand/fill/sand etc until I got it to be as flat as I could. This is what it looked like at first:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I then added more to the bottom molding to give the tablet some support from the sides as well. I think this will help in keeping it stable. These are depicted by the yellow arrows. The filing/sanding I was talking about was referring to the red lines in the pictures. I am trying to get these surfaces to be as flat as possible so that the tablet will mate closely with the bezel.
I plasti-dipped the bezel, which FYI matches remarkably well with the interior plastic. Then I attached elastic bands traversing each other diagonally to hold the tablet to the bezel. In addition, I attached magnets around the bezel, which can be seen as the black circles around the edge. I will explain why I did this in more detail as I continue with the install. I also started messing around with the tablet to make it how I would want it in the car. I am using the 2013 Nexus 7 running Paranoid Android so that I can customize every app individually. I put the buttons on the side and made them red to match the interior. One thing that I am happy about is that the way that I chopped up the bezel, I left the camera, light sensor, and notification light open to be used. This way I could even do video calls (granted I will be looking at the road) which might be pretty cool. Here are some more pictures:
I then removed the stock headunit.
This gave me more room to work. I bought a CR2-VW2 harness by PAC from one of the VW forum members. This harness allowed me to connect an aftermarket headunit and retain the stock audio system (amp, speakers etc) but did not include steering wheel controls, which I did not need anyway. I chose the Alpine UTE-42BT for a few reasons. First, it is only $88 which is very reasonable. Secondly, it doesn't have a CD player which is good since that feature would never be used anyway. It has a front auxiliary port and bluetooth handsfree built in, which will allow me to use handsfree from the tablet. I will explain the intricacies of this in a more detailed write up when the project is completely done. As of right now, this is how it is looking:
Pardon the mess, the project is ongoing =) As of right now, the tablet is running on battery, but I am planning on setting it up so that it receives power when the car starts, thus turning on the screen, and when the power shuts off, the screen timeout of 7 seconds will kick in. I'm realizing that 16GB is not a lot of space for something I want to keep music on, so I recently bought a USB OTG cable to mount external storage and I'm waiting for that to arrive. Does anyone have experience with using USB OTG that could provide some insight into this? Will Google Music pick up on the media on the USB storage and add it automatically if I use Stickmount or something like that? I'm going to see how that works out before I decide I need to buy a 32GB Nexus 7 instead. To charge it (if USB OTG works, meaning that the micro USB port will be taken), I will get a wireless charger and plug that into the cigarette lighter for power. If USB OTG doesn't work, I will power it directly using micro USB. One thing I would recommend to anyone trying this is to pick up a ground loop isolator, since charger and using auxiliary at one can lead to some interference. There should be more to come over the next week as I get some more of these peripheral supplies. It sounds great though, and the functionality is far superior to the stock headunit.
Very amazing. I've a plan to put a tablet of some sort in one of my cars! you beat me to it long ago seems like! I wanted to connect my rasberry pi to some sort of 7inch touchscreen!
but this is wayyy nicer.
PROPS!

I can confirm this for wireless charging and USB OTG. On mine the wireless charging cuts off when the OTG cable is plugged in.

Oh shoot, you can't do wireless charging and USB OTG at the same time? That is going to be a major problem for me. Well I'm glad I didn't buy a wireless charger yet. The USB OTG is working out like a charm, but I definitely need to have a long term charging solution. I don't want to have to take it in and out. Do any of you know if anyone is working on a kernel that allows USB OTG and wireless charging simultaneously?

Could you somehow use Bluetooth instead of OTG?
Options!
I made a steering wheel interface for Androids, n7 primarily.

For one, I can tell you that you can Charge and use USB OTG if you install the right kernel.
read here too
http://forum.xda-developers.com/show....php?t=2113259
I haven't tried the pogo pins and USB OTG together, that might work. Otherwise there are a few options.
(to be clear, the best option would be a kernel that allows USB OTG and charging, at the same time. )
:good: First, probably best, Buy an adjustable regulator like this : http://www.seeedstudio.com/depot/adjustable-dcdc-power-converter-125v-35v3a-p-1534.html and adjust it to 3.9Volts (lipo used in tablet works between 3.7v and 4.2v) , use the always on BATT 12v input. Then remove the back cover of the N7, remove the battery, and power it directly from the car. http://www.ifixit.com/Teardown/Nexus+7+Teardown/9623/1 It looks like the black, yellow and red wires would be Ground, Vcharge and Vout, but you'd need to verify. You'd probably have to cut the wire. You might want to order a replacement on Ebay to use. You can then use tap to wake to turn the screen on or a USB micro setup like the one I made to tell the tablet to turn on/off with the key (act as if a keyboard was plugged in and you hit the power key).
Second, and most tricky. USB OTG uses pin 5 as the sense pin for Host/Client. IF you don't intend to use Host mode all of the time, like just when pressing a steering wheel button, you could use a Microcontroller to trigger the mode.
Third, Would be to charge when the car is off, and USB host when the car is on. Again this comes down to using pin5, or if you follow Kuchar09's post he has a wire diagram for this.
---------- Post added at 01:37 PM ---------- Previous post was at 01:14 PM ----------
Sorry, I just realized yours is a 2013 version. Same deal, not sure about the kernel, but someone will make one. Also not sure about the touch control, it needs kernel modules to work, so again compatible kernel.
BUT my first option, still the best work around.
Here is the tear down http://www.ifixit.com/Teardown/Nexus+7+2nd+Generation+Teardown/16072/1 and you can see the battery still uses wires. you'll need to test what they are. Powering the tablet with a regulator in place of the battery would be ideal.

Yeah, my first thought was a wifi HDD as well. Just give it power and put it somewhere out of the way. personally, I'd wire it and put it in/under the glove box for easy media adding/removal.
I've done this in several vehicles so far.
What are you doing about heat in a parked car in the sun? At 90 outside, in my sons car ( lighter colored cloth interior ) it's approx 110-115 in the car. In my 350z with black leather, it's over 120 inside.... With the hookup you have going, making that a removable mount would be pretty easy with a pair of nice magnets to snap that entire enclosure and tab into place. Makes it nice when you have to leave the car in the sun for any amount of time, or to work on it, etc.... I've seen 1 screen physically crack, and a 2nd device just flat out die. Something to keep in mind depending on where you live.
As far as the power issues.... I use tasker. When the power is cut to the device, I force it into deep sleep and airplane mode. It will go for 2 weeks+ sitting there idle without dying. When the power is fired up, wake up ( no lock screen ), and set the screen to full bright and no timeout. No need to hack the device. A kernel for this would be great like the orig N7 had, but until we get one, this will work too.
Also, don't go BT to a head unit IF you care about the sound quality ( compressed audio sucks and if you have a good system, you'll hear the difference ). Go with a DAC ( from 30 to 300 bucks depending on what you get ). The sound quality will be much better then using the compressed BT crapola. Or even go out via the head phones, it's still much better then BT.
Just some things I've come across doing this for a few years now with various devices.
Oh yea.. and put an anti glare screen protector on it. Play with them to find the right one, or your screen will be invisible when you have glasses on. IPads do the exact same thing. Once you go into landscape mode, black screen ( put on your shades and just turn it, you'll see.... it sucks )..

How exactly do these wifi hard drives work? Can I connect to a wifi hotspot while using one of these? How exactly is the storage mounted? Do you have to use a file explorer to access the files, or will Google Music be able to find the media automatically? ie media scanner

Good advice. Yeah, that's the plan with the magnets I built into the bezel. I am going to put some metal/magnets in the cavity where the tablet will go and I'll use those to put the tablet/bezel combination in and out.

I was thinking about rolling on battery alone, but I thought it would be nice to run it from a charger. I'm realizing that there physically isn't room to use the micro USB port, so I think I will use a wireless charger. I figured I would use Tasker to turn the timeout off, turn on the wifi and bluetooth, and other stuff like that with power, and reverse it when the power drops out. I am planning to use the auxiliary output for now.

That is definitely something to think about. Are there any brands you would recommend or have experience with?
You could also mount a 120mm fan behind it for when it's hot. Heck, I bet the fan could run while the car is off and draw next to nothing from the battery. You would only need to run the fan at a few hundred rpm as well.
Fiio makes some pretty good ones without breaking the wallet. You can bypass the charging issues by just going headphone jack into the DAC, then into your headunit via an aux port (3.5 or RCA, they make DACs for each). You can go with a USB DAC as well, but I think there are driver requirements and crap to deal with on top of the power issues when hooking up via the N7s usb port. Just sounds messy so I've not tried it that way.
I pulled the HU from my son's completely and go from DAC right into the amp ( well into a crossover first so I can pull the sub frequencies into a separate amp as well ).
I kept my HU in. I just like having the 2 7" screens on the dash so I can still have full nav on the HU and music on the N7.
Oh and I just checked, the spigen ultra crystal screen protectors will cure the landscape sunglass issue. I'm sure others will as well, but I can verify these.
The hdd's create a hotspot the tablet would connect to. I don't know how the tablet would react as far as scanning media. You could soft link the files from the hard drive to the tablet if it doesn't just recognize cans play them. The Seagate is dlna compatible so it should be easy to play from.
A small fan would be easy enought to cool the tablet, you could even have a temp sensor on it, think attic fan, that would just come on automatically. Also of you follow my suggestion and remove the battery, and power it right from the car, the back cover would be off so cooling would be easier.
I run my system phone to Bluetooth (Sony sbh20) straight to my amps, it sounds great. All this bs about USB DAC's is mostly BS. The tablet has a DAC inside its what is converting the 1's and 0's to music. Yeah it might not be the best DAC on the market but I don't think its the source of bad sound quality on most any unit.
I personally am not a fan of hiding a deck just for the amp inside of it. This basically makes zero sense. However many new factory sound systems have the head unit specially eq'd to make the crappy speakers sound good. You might have to get new speakers to make a direct tablet -> amp -> speaker method sound good.
I did car audio for 10yrs I know a bit about it.

Hey XDA!
[This is my first thread, so please excuse any abnormalities you may find here. Corrections/ help would be appreciated. Thanks!]
As tech has progressed in the last couple of years, I have come to replace my beloved nexus 10 with my ever-more-powerful LG G2.
This transition is soley because of spec enhancements in recent devices, but very recently I realised what a horrible waste of an amazing (and still somewhat powerful) device that is, and I'd decided to do something about it. So, I shelled out a few of my Great British pounds (less than £5) and bought myself a microHDMI cable, and a USB OTG cable. I found an old USB keyboard, USB mouse and powered USB hub (not sure if it's necessary to have a powered one, but its all I have to hand), and got going on my small project.
[TL;DR: Ive got an unused nexus 10 laying around and a few other PC peripherals, as well as a microHDMI cable and decided to start a little project]
I realized the nexus 10's potential because of all of the useful (and more importantly- seperate) ports it has:
- MicroHDMI out for a monitor/TV (not necessary)
- MicroUSB port w/ support for USB otg
- Pogo pin port for charging, so battery is not an issue.
All of these things together can be used for a portable android- powered PC! So I plugged in all of my cables, and thought I'd be ready to go, but of course, that would be too easy.
Things that worked:
- USB otg cable and respective devices (keyboard, mouse, 16gb USB stick)
- MicroHDMI video out (sorta)
- Pogo pin charger
Things that did NOT work:
-MicroHDMI video out (screen size/ratio/density)
-MicroHDMI audio out
-Easy usability (phablet-style stock ROM does not like mice.)
Fixes/ work arounds:
1. MicroHDMI audio out:
This was probably the easiest (and therefore first) fix. I remember reading on another forum about the same issue, and it is easily resolved by turning the nexus 10's volume all the way down before plugging the MicroHDMI cable in. Worked first time, like a charm. However, in some cases this does not work and may require flashing another ROM, I personally reccomend cm10.2's most recent stable rom, as it is exactly what I am using. (if you are looking for the same outcome as me, this rom maybe a requirement anyway)
2. Ease of use:
This part did require flashing a new ROM. I used CM10.2's stable build, and banks GApps. Other supported ROMs are listed in the thread linked in this "2. Ease of Use" section. I used the flashable zip file listed in this thread: ( http://forum.xda-developers.com/showthread.php?t=2451956 ), to change from the mouse-unfriendly phablet ui, to the mouse-friendly tablet UI. This made the nexus a lot more useable as an android desktop/portable PC.
3. MicroHDMI video out:
This is a little more awkward, but it is still relatively easy and do-able. I did a little searchng and found this post ( http://forum.xda-developers.com/showthread.php?t=2294786&page=3/#25 ) which links to an apk specifically made for fixing this purpose. I downloaded and installed the app (Named something like ScreenRes I think - the exact name escapes me) and checked the box which said "Resize the screen when HDMI state changes" and used these settings for a 39" 1080p screen:
- Screen height: 1080
- Screen width: 1920
- Screen density: 280
Unplugged and re-plugged the cable, and voila!
PLEASE NOTE: This apk does require root access, and I have ONLY tested it on the CM10.2 stable build. This is the ROM I reccomend for this project/purpose. Also, dont forget to thank sbradymobile for his easy-to-use app!
The end result? A very useful android PC attatched to a beautiful 39" display bringing new life into my once-dying nexus 10. It's a shame to replace the beautiful screen on this thing, however with a cheap tablet/phone stand you can take tablet away with you and a keyboard and mouse without loosing any settings, files or convenience for a more portable android PC. Granted, It's not the most beautiful looking thing, but with a little cable management tou can make a neat and tidy android PC set up.
This is particularly good for productivity (e.g with apps such as kingston office, or- creating threads like this on XDA ) as well as media consumption, for things such as movies and with apps such as cheapcast or droidmote you could make a nice mid-point between a chromecast and a fully fledged laptop/PC.
Sorry for such a long post, I just wanted to share this idea as even though I'm sure there are others similar to this, I think there are other people like me finding their tablet being used less and less.
Please feel free to leave your thoughts and questions below! Thanks!
Sorry for the long post
Just a minor suggestion. When an OTG cable and the pogo plug are both connected the pogo plug does not charge the N10. Do not believe the charging notification as it shows charging which is false. There is no ROM for the Nexus 10 which can correct this issue.
As you mentioned a powered USB hub in your configuration then purchase a OTG Y cable so that one end goes to an OTG device as usual a normal M/F USB cable goes from your Y OTG cable to a powered port on the USB hub. It will only trickle charge but that is better than using battery only.
Sent from my Nexus 10 using XDA Premium HD app
Thanks! Ive realised this and will ammend the post soon. This is a little annoyance however as the nexus 10 has a rather good battery life I can use it till I'm done and then put it on charge with the OTG removed

New Edge Mustang Nexus 7 Install

Hello all, I am new to this forum. I brought my thread over here because on the forums I post on normally for my car they seem to have 0 interest in the subject. My goal is to receive help from you guys, as well as maybe help any of you out! So to start off with a little history of the car. The car is a 2004 Mustang with non-mach stereo. I Currently have a single din radio and 2 amps (1 for door speakers, other for 2 12" subs), and all upgraded speakers and wiring. I have always wanted a touch screen radio and navigation, so that i did not have to use my phone the whole time while driving. I was looking into pioneers and alpine double dins, but for the features i wanted i couldn't justify spending 1200 bucks. So that left me at the same place i started at. I started browsing tablet installs when i discovered one of the guys i follow on instagram put a Ipad Mini into his dash. This really got me thinking about what i could do, so after about 6 months of juggling the idea, and doing some heavy research about which tablet to use and which Roms were best for in-car installation i found the Nexus 7. And that Triggered this build, which i will regularly update as the build goes on.
So to start off this is the list of stuff that i will need or have acquired, acquired is marked with blue, and will also have the price and total at the end. Items that have unknown prices are ones that i have not decided what to get or cant find what i want.
Need/Have:
- Nexus 7 2013 (32gb) (115.00 - Staples)
- Timurs Rom (28.94 - Donation)
- Clarion EQS746 (54.49 - Amazon)
- Behringer UCA202 USB DAC (29.99 - Amazon)
- 2X DC-DC Converter Module 12V To 5V 3A 15W Double USB Output Power Adapter (11.99 Ebay)
- USB Hub - Powered (unknown)
- Back-Up Camera (16.87 - Ebay)
- Easy Cap (Unknown)
- FM transmitter (Unknown)
- PlexiGlass (21.99 - Lowes)
- RCA Cables (6.99 - Radioshack)
- Right Angle OTG Cable Adapter (4.99 - Amazon)
- OTG Cable with Power (3.99 - Amazon)
- Micro USB to USB (6.98 - Amazon) Need this to connect the right angle to the OTG cable
- Metra 95-5026 Double DIN Installation Kit (9.29 - Amazon) Need this for parts of the mounting method
- Metra 70-5520 Wiring Harness (4.49 - Amazon) This is to connect power
- Hard Snap on Case (4.29 - Amazon) Part of Mounting Method
Total Price: $320.20
This list is for stuff previous to nexus 7 install/as well as some apps for in dash installation:
Hifonics Hfi1000.1d (129.99 - Amazon)
Hifonics ZRX600.4 (93.00 - Amazon)
LI12D4 - Incriminator Audio 12" x 2 (508.00 - Amazon)

Nova Launcher Prime (4.00 - Play Store)
GMD Auto Hide Pro (2.49 - Play Store)
Total Price: $744.10 - Most of this is tied up up in speakers/amps.
I chose Timurs rom because of the dedicated support forums, and the amount of followers behind the build, This rom allows for fixed installation, which is most likely what ill be doing. It enables OTG so i can hook up a USB hub to it, and have access to back up camera, music storage, and also play audio through the DAC.
As far as mounting method for the tablet will be doing away with the radio completely and putting the tablet in its place like so (Imagine it behind the bezel lol)

"lightbox_next": "Next",
"lightbox_previous": "Previous",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
For mounting I stumbled upon different ways that people have accomplished and didnt like any of them, most of them stayed out of the bezel, and the ones that were in the bezel were fixed and was not easy to remove.... then i found this build, i loved the idea of having it fixed, but then again easily removable if need be!
Subaru In-Car Install - Mounting
So that is when i started to build this!
It is pretty messy looking right now, but i will be painting it black so that it will blend with the case, and look like it is meant to be their.
I have a bunch of parts coming in the mail this week, that is the only thing that is holding up the In-Car process of the build.
I had a bunch of free time yesterday so i decided to start working on the UI for the tablet. I found a build that someone had done in a BMW that i really liked, and they even posted their PSD file for it. I began Chopping it to meet my own personal needs and build, and came up with this!
On the Tablet side, i just used it as a background and created invisible widgets that were placed onto the "Icon" and directly linked to the corresponding app. After i got all of that worked out, and added some widgets to the screen and removed the navigation bad i decided to work with tasker a little bit. I wanted the device to stimulate when power is off to key, and when power is on to key. So i created two different profiles and added task to each, they are as follows.
Power ON:
Airplane Mode - Disabled
Display Timeout - 23hrs
Display Brightness - 158
Popup - Welcome Back
Media Volume - Level 14 of 15
Bluetooth - ON
GPS - On
Wifi - On
Auto Sync - On
Power OFF:
Popup - Booting into Low Power Mode
Display Timeout - 15s
Wait 10s
Bluetooth - Off
Auto-Sync - Off
Wifi - Off
Music - Stop
Airplane Mode - On
TaskKill - Chrome/Maps/Pandora/Spotify/PowerAmp
Go Home

I will update this regularly, if you have any questions comments or anything else please post below in fact i encourage it!
Also i am looking for ideas to install a Female input AUX into my Center Console for a factory look into the EQ, anyone know how?
Looks good!
In regards to your female aux issue, has your main head unit got more than one aux input? If so there is your answer. If not I know turtle beach used to supply a female 3.5 to 2ph piggy back which would do it just make sure the tablet is muted first.

I am getting rid of the Radio unit all together. Using the USB DAC to send audio to an EQ which has an input from the DAC, and the AUX input. The EQ has a physical push button to switch between Main IN and the AUX IN inputs. So i wanted to Run a Female connector to the center console so that i could just plug in an male cord to the Female Input and hook that up to anyone's phone if they wanted.
Sounds like you're already there then. What was it that you were uncertain of about it?

why not use the factory installed aux. Simply solder the cable inline with the factory cables and then hook it up to the aux of the clarion. you don't have to cut the cables just simply splice into them but make sure your connections are good and there is no cold solder as your sound quality is going to depend on it. you can also do the same with the USB, if you car has one, most of the time there is an extension mid way in the center console.
I am in the process of doing mine and I ran into that same plexi 2din case attachment...I might be going that route too as it can all be removed as one unit. I am also adding LEDs for the powers of each device. I will be able to troubleshoot faster knowing what may be wrong, ex: led for step down, led for otg, led for each usb hub, but hopefully nothing goes wrong. Good luck on the project. I too will be using Timur 2013 lollipop, it only makes sense to you use it since I have no idea how to compile something like that.
btw, if you are going to have all that incased inside that plexi box, you should consider getting a 5v/0.21amp Usb powered cpu fan to keep things cool in there, just connect it to the hub.

Aux was not an option in my year mustang. The plexiglass just helps keep the components in one place, if i ever decide to rip it out when i sell the car. I am running into an issue on where to install the EQ however.
Is this any good to you?

I'm interested in how you guys are finding Timurs build considering it's the first build I've seen that's paid for.

I havent bought into yet. I am still considering my options and to see if there is a way around it. I got most of ny pieces for the build in already, but i have yet to mess around with it. I am assuming a custom lolli rom, something like cleanrom with experimentalx, might be all I would need, but your needs may be different. I'll start my own thread once I have everything in order.
As far as the aux...just buy an extention aux male to female or for a more professional look and even more functional they sell receptacles that take the place of your cigarette lighter, unless you need one of those, that offer an aux and usb. You can run a usb powerd from the step down to charge phone or usb extension from usb hub for music.
Also, the fan is to dissipate the heat that is going to build up from your car sitting in the sun and the greenhouse effect the plexi is going to give your electronics. Just my opinion. The EQ can be mounted in any position from under the dash to inside the glove box. The one thing to consider is how often you are going to access the knobs on it. If you are going to do it frequently then it needs to be mounted somewhere in plain view. I am not too familiar with the car. Good luck on the build though.

I was mostly interested in Timurs due to the huge support behind him, and all of the drivers, and programs already built into his Rom/Kernal. It just made it so much more simple to me. Also for that Aux Cable, i want to retain a factory look, and i cant see that being very factory looking inside my center console. I think i will end up using the JBL one that i posted earlier, it looks more factory than the rest and i can ensure that the quality is the highest.

Im going to run temp activated fan i think to control when it gets to hot. Seems the best for me since it can be on when the car is off to keep it a little cooler in the summer. That small of a fan wouldnt drain the battery too fast either. AS far as the EQ, i chose this EQ because of the physical Volume nob. Im thinking that i am going to end up moving the buttons for my Fogs, Defrost and Traction control down, and glass the EQ in their spots.
Well, i went to install the tablet today. Ended up breaking the OTG cable so i have another one on the way by saturday. Will update when it comes!
Sorry to hear that. You must have done something sever though, all my usb otg cables have been attacked with the Dremel to get it in the tight space I havevand they're fine :S
That aux I posted up is what you asked for, cheaper. If you have a fold down cigarette tray then it could easily hide in there and still look OEM. The jl audio one you posted looks like it takes over the 12v supply with that cap in it, so if have a quick measure.
Whilst we are on the subject of 12v, what have you done for power? I'm looking at running a usb charger off the back of my lighter/12v so you can't see it in the future. Just curious if you've taken power from elsewhere.
In regards to kernels I run glitch on a stock 5 build and that does usb otg audio and fast charge absolutely fine. The only issue I've seen so far is occasionally I have to reboot for the audio to switch back to the DAC. Let me know how you get on with Timurs and if it's worth buying

The cable didnt break, but the tip of the OTG cable did. When i was installing i had to bend it a little to go into a notch i made in my console, well it bent to much and wouldnt work anymore. I may try and shave the supporting rubber around it and make a right angle from it.
Yeah looking more and more of it, i think im going to go with the JL one because i have a cigarette lighter outlet in the bezel on my dash that doesn't work that well, so i will just replace it with that. As far as power, i had bought 2 DC-DC 15w 3a usb chargers that you wire directly to a 12v supply, turns out that they didnt work so im contacting the seller to see if it is my fault they dont work or just faulty. If it turns out that it does not work regardless of what i did i am going to go to radio shack and pick up an accessories socket and glue it to the inside of the box i made so it wont be seen. Turns out that the harness i bought from metra has a power and a ground and it will shut off and turn on as the key is turned. So if it comes down to it i will hook it up to that. Also seeing as my remote on wire wont be connected to anything i hooked that up to the power to the radio as well and piggy backed the EQ remote on from it. I will let you know what happens with the power though, i have it currently hooked up to the cigarette lighter that doesn't work all the time, and it seems to be doing fine.
As far as timurs rom goes, it has everything i want in one rom. It has all the files for backup camera, it has power management, DAC doesnt have any issues, it is a seamless product with all the necessities i needed in one build. One of the reasons i went towards that rom is because of the amount of stuff in one place that i wouldnt have to hunt for!
Its all finished for the time being, i will start adding on the other things later on as i need them.
Im looking for a super super thing auxiliary cable. I litteralt have the space of two quaters. Tried removine all the rubber and folding but still the mettal part is too long
dude this is awesome!!
I wish I knew how to make stuff like this, I own a 04 Mustang and damn it now I wanna have my N7 there lol

Local Staples had them on clearance, had trouble with register taking my card. Manager gave me 15% Discount for my troubles.
UPDATE: System works fine so far, only one little bug that i am working out. GPS and wifi connect and work properly, USB DAC works flawlessly, charger works well. The little bug is that when the tablet comes out of firm sleep the buttons dont seem to work except the back button. Dont know what it is but im looking into it.
Where do I buy Timur for my nexus 2013? I went onto his website but couldn't find the donation or download option?
so i have a somewhat similar install in my e39. I am doing 3.5mm to RCA right now, i want to make the switch over to USB OTG.
What specific parts do I need to make it work??
PS I have a pre-amp RCA input processor that it has to connect to.

Is this the OTG + Charging solution some have been waiting for?

Like a few others scattered around the subforum, I'm looking to do an in-car tablet install. Like others I hit the "Can't charge and use OTG at the same time, you need an ancient nexus and Timur's" just as old but revered ROM." wall.

The second post there, refers to a vendor LAVA whom "LAVA is the only manufacturer of adapters for Samsung tablets that allows that since Samsung doesn't sell anymore their hubs" (from that post).
Confirmed that the Compatability list shows SM-T580 (the device amazon has factory refurbs for 200$):

Would it be possible this is the device to make the magic happen? http://lavalink.com/samsung-tablet-adapters/
EditToAdd: Tech Spec sheet here for the meaty innards: http://lavalink.com/wp-content/uploads/manuals/sts_product_family_manual.pdf Main takeaway for me was don't extend the cable to the tablet.
Also found the "cheap" lol single port on amazon with a wide swing of reviews: Encouraged by the long one that says it is working with external DAC: https://www.amazon.com/SimulCharge-1-port-Adapter-Samsung-Galaxy/dp/B00MOQFUQM
Also this mini-writeup shows one in use in 2015 with DAC, am I missing something on why this was a wall for many?: http://www.diymobileaudio.com/forum...-usb-hub-samsung-galaxy-tablets-charging.html

On the (i hope) tail end of the first version of my dash tablet install, and after my research and work over the past few days, I will try to answer my own question -- just for others. no pity for me. OTG-Host was not a "must-have" (yet).
My big mistake (i think) was not being aware of the distinction between OTG-Accessory and OTG-Host. The Lava-link hub/cable in my OP allows OTG-A and charging the device. OTG-H seems to be a different animal,.. something that the kernel and maybe the hardware has to support? I have flashed Extremely ROM on my T580 and a USB keyboard plugs in to OTG cable and is detected, but a USB RLT-SDR device is not detected (nor powered).
So I guess back to the beginning, still need Kernel support for OTG-Host? Correct?

SM-G900T snapdragon to Android streaming box? Using internal video output

Ok, so i have my Galaxy S5 tmobile that ive been playing with recently. awhile ago i tried to replace the rear facing camera, and the loudspeaker. unfortunatly when removing the screen, the digitizer was damaged. oled was working great. i would just use a bt mouse to navigate. well last night i pulled the phone apart to compare the amoled connection to that of a S7. just to see if i could throw the S5 screen onto my broken S7 to attempt to setup screen mirroring to my tv and be able to use it with a keyboard and mouse for general streaming.
I left the screws out of the midframe assembly of the S5 and it fell off the table after being reasembled. (love when the pets get into my workshop)
anyway, it was just enough to crack the very corner of the OLED and now there is no functionality to the screen.
ive been thinking about trying something that i just havent seen before, and cant find any information on at all.
There has got to be a way to take the ribbon cable from the S5 screen with the connector and splice/solder into some kind of digital video output. also the audio to the loudspeaker adjusted to low-line and connected alongside the digital video to make a single digital A/V output.
Basically i want to have my BT keyboard and mouse and be able to have it outputting video to either a Moniter, tv, wireless adapter of some sort. i would leave the OS pretty much the same minus alot of needless software at that point, and be able to turn essentially any tv with HDMI or digital video in, into an android smart tv..
i have arduino uno kits and Abillion cables of all sorts.
if anyone has any insght to the format of video coming from the OLED connector, or a pinout , any information that would help me get the ball rolling on this. i would be extremely grateful.

Don't like MHL adapters for some reason?

They are nice and all. But that would mean I would have to spend money on something to make it work... Also mhl adapters take their own power supply at 5.0v, which means it would have to be plugged in somewhere during its use. Which I had planned on just using a couple 8000 mAh lithium batteries wired in parallel to power the phone at 3.7v. Getting me somewhere between 6 to 8 days of heavy usage before a recharge. And would make it much more portable.. Maybe even construct a small enclosure with a fan out of one of my CCTV cameras. Even if I had to convert the video and audio signals using a microprocessor, I wouldn't have to spend a dime doing the entire project if it works the way Im imagining it too. One of my main objectives with this project is to use parts from old equipment that I already have.
This is more about doing something creative and new with old Galaxy phones that have no other practical use.
Yes I could order an android box off amazon for less than 20$ and do what everyone else did to stream...
Yes I could order an mhl cable and set it up that way....
Yes I could put a new display assembly on it and use it for dev....
But if everyone thought like that, android wouldn't have existed in the first place.
