Car audio and phone guy question - Nexus 4 Q&A, Help & Troubleshooting

I just had a new deck installed, here's the one I had installed, http://www.pioneerelectronics.com/PUSA/Car/CD-Receivers/DEH-P8400BH
And when I plug my phone in to the USB, it says device unrecognized. Is that normal for Nexus devices? Is there any fix for it? And no bluetooth information is displayed, i see its something to do with something that LG or Samsung puts in their branded phones, so its absent from a Nexus, is there any rom with it in it?

Hey there. Same deck and same phone here. For the USB to phone, don't bother. Never got it to work myself. As far as information displaying while playing, many of the custom ROMs support this (CM10.1, AOKP, etc.), so you might want to give one of them a shot. I'm not sure this is something that can be added, or if it's something that that requires a whole ROM to implement.

The nexus 4 doesn't use UMS for mounting. It uses MTP. Unfortunately it won't be compatible with your deck or any other device for that matter.
There aren't any ROMs that will change that either.

Get appradio with arliberator. If you didn't know what that is you can thank me later

I'm guessing this wont be in any AOSP based ROMs though? None of the ones I've used support this. Maybe I'll try CM when they finally get a stable version out, can't stand nightlies.

Haha, gotta love a cheap solution. Esp as he's just bought a new receiver.

Don't bother with cm right now. Apparently because of the new Bluetooth stack Google used in 4.21 they had to pull out AVRCP v1.3 (the Bluetooth control protocol that allows for song meta data to be sent to the headset) out of cm10.1 and revert back to v1.0 that only allows control...No metadata.
Stock Android only has AVRCP v1.0 so that's why it doesn't work on any stock Nexus device.
...but my wife's GS3 has AVRCP v1.3...boo.

From the thread:
What's not working:
--Audio Capture (voice commands, camcorder audio)
--Bluetooth Bluetooth actually works for connecting and data transfer..will not work for audio as I haven't gotten there yet.
--Chrome Beta not working yet
--YouTube not showing in market (and probably a few others (although you can download and sideload YouTube from the link below and it works, also webviewing YouTube works)

I personally wouldn't really want to use that unless at least the Chrome and audio issues were fixed (those are also the reasons I abandoned the AOKP ROM here).
I use the stock browser, and i can wait on Bluetooth a2dp, so yeah, if those are deal beakers, not a good rom, other than that, it's working flawlessly...

No ROM that is made from AOSP has these features that you "need" in them currently due to kernel source not being complete from Samsung.
Blame Samsung, not any development. Have fun on TouchWiz while the rest of us test drive the future of our tablets.
PS: No one is making you use these roms.
I didnt't mean to sound critical, only to mention some of the limitations that prevent me and people a lot like me from using it as a daily. No offense or criticism intended.
Can somebody link to cm9, and make a small guide on how to root and flash.

CM9 with stock kernel?
Would it be possible to make a CM9 rom with the stock kernel so that mic and other things work?
To answer a couple of questions, it's my understanding that it's against forum rules to link to an outside forum....afraid you'll have to google it.
Also, CM9 requires an AOSP kernel, so the stock kernel wouldn't be compatible.
Not the answers anyone wanted, but that's my take.
xpensen causes
The sound not working wasnt because of the kernel source. I just hadnt gotten to it yet
Samsung released new kernel sources that work so the heavier fixing can begin. Last build had working mic as well as the sound. Still need to get bluetooth audio working but dont have a headset to test with :'( . Going to see if I can borrow one for a few days so I can get it working.

How to use a usb keyboard

To get it working I saw online that you need to get into advance options. Where is advance options? I don't see it.
Sent from my DROID RAZR HD using xda app-developers app
You dont need to set any options at all. Get an otg cable, and plug it in. Thats it and thats all.

Not working for me. I've tried two different ones and I know the otg cable works. I plugged the keyboard in and nothing happens

Different otg cables are made for different devices. Some wont work with the n7. There are absolutely no options you need to set for a usb keyboard to work. None. It is completely automatic. I have used it with stock and many custom roms. No settings needed. None. I would bet that the otg that works with your rzr will not work with the n7.

I used this otg cable on my 8GB nexus 7 with an external sd card. Now I have a 16GB and I'm trying to use the same cable with the keyboard. This is what I saw on Amazon:
I'm just trying to find those settings
Sent from my DROID RAZR HD using xda app-developers app
I dont know how many ways to say that there are no settings for that. Either it works, or it doesnt. There are NO options for it in settings. The ability to use a usb kb is built into the kernel. Are you running stock or custom? 4.1.x or 4.2.x? Which kernel?
Also, the pic you posted is from January. That means that the poster was stating settings from either gingerbread or honeycomb. Alot of those settings are not present, nor needed in jellybean. In short, those settings are not going to be found on an n7, since jellybean is the only android revision it can currently run.

Need USB port waking up app or shortcut.
Hi guys. I have a N7 and I bought http://www.ebay.com/itm/Black-Leath...es_Covers_Keyboard_Folios&hash=item484c513364 .
The keyboard is nice since it's also a case- the only issue that is bothereing me is that after tablet goes to sleep. so does the keayboard since it is powered by my tablet wia micro usb port. But that doesn't bother me. What bothers me is that when I start using the table again I everytime have to unplug the case and plug it back in so that nexus activated the usb port again and starts povering the keayboard. What would make this case perfect would be some kind of app or just a shortcut to put on my homescrean that wouls simulate the unpluging/plugging back in...
This would realy make my nexus7 with the case perfect.
I downloaded a couple of script running apps but don't know anything of calling the USB port and waking it up... and haven't found any scripts to run and test.
Let me know if you know/find something about this...

Anybody got nexus 7 to work with jawbone up?

I am interested in buying a jawbone up but from what i can read online no one has successfully synced jawbone up with nexus 7..wondering if experts here have had better luck ? Nexus 7 is not on their supported devices at the moment but you can install the app.

Well to answer both your question, I have to say it does work with the nexus 7. the app is not currently in the app store on google play, you have to download the app separately. a quick google and you shall find what you are looking for. its slow to upload, but works. goggle jawbone up apk for samsung note 2, this is the version I am using and I have to say it works.
Nexus 7 is missing line in support
Do you also get the arm wrist to sync with your nexus 7?
I read that the up needs line in support on the audio jack and neither the old or new nexus 7 provide that.
Of course you can install the app but without syncing there is not much sense in it.
Would be glad to hear that i'm wrong...

It works just fine on my Nexus 7 2013, I can sync it with no problems, so far. I am running stock KitKat (4.4.2) ROM, if it matters.

Jawbone UP v2 (audio jack one) + Nexus 7 fhd 2013 works great together
get the app from here apps.evozi.com/apk-downloader
you can get every app directly from the store. just put in the link or the app name (com.jawbone.up) and get it.
the first time i plugged the wristband didn't work at all.. sync error
i hard reset the wrist the first time (9 click + 1 long 30sec click) then i hack with volume and after some plugs and unplugs it worked.
if volume is max or min it doesn't sync.
i hope it helped.

Paranoid Android and screen mirroring aka Miracast

So I am running the last 3.60 paranoid android and I am having problems with getting a sony Kdl-70r550a to connect to it via screen mirroring that the tv has. I have already updated the TV firmware to the latest that was available. When it does connect, it displays what I can only describe as when an NES cartridge needed to be cleaned or wasn't in all the way. Basically weird blocky artifacts with only small bit of picture color showing.
I have tried changing screen resolution on my phone and even DPI to no avail. I have also tried using a Samsung s4 brand new out of the box, but being Samsung, gives registration failed when attempting to connect.
Sounds like some sort of copy protection. Try turning off hdcp.

This makes perfect sense and would explain it. Problem I have now is that I can only find "Hdcp checking" under developer options, after changing it to never use hdcp checking and trying again, still getting same issue. Any other setting I am missing to disable hdcp?
Flash cm10 there is an option to disable it
Sent from my Nexus 4 using xda premium
OK, flashed back to CM10.1. Where is this option located?
Going to request PA to add the feature for disabling hdcp for next stable build.

So I tried and tried and even with the hdcp handshake off gives a picture but its laggy and comes in and out. Has any else tried this with any other brand tvs? At this point I'm blaming Sony, as I know with external devices that support Miracast will work flawlessly. Guess an eventual firmware update may fix it. Buyer beware.
PS thanks for your help.

Are you still using your Q?

Is anyone still using their Q now that it's been completely abandoned by Google? If so, in what ways are you using it? I was hoping someone here would hack the Q, but it looks slim. Should I throw this thing away? I want to use this things amp!

After they shut down the servers for setting them up, I quit using it. If you use cm 10. 2 with amp support and cheap cast its almost like it still works, but i haven't taken the time to put it on yet. There are guides. Don't trash it though. There are still people that will have uses for them as a desktop computer.
I haven't used mine in 6 months either but I am gonna dust it off and try to load 10.2 on it next week now that the hdmi and spidf are working. Does anyone know what keyboard and mouse combos work? I thought it was a Microsoft wireless 800 combo that I was using last time with wireless adb since there's only one USB.

I just installed cm 10.1 using the method posted by user ianandamy. Works great and my input methods are a Microsoft wireless mouse with with an OTG cable connected to the Q, and I have a wireless Bluetooth keyboard. The only things I would like to see fixed are the primal LED lighting function, and a way of powering off the Q other than unplugging it.

Does it allow it to run like a chromecast and stream media from the phone ? I miss my original q

Actually found mine in the cupboard the other week, got it working thanks to a few forum posts here, running CM on it, using it as a quick XBMC streamer + android games console with a Moga BT joystick... works a treat.

If you install CM on it and then install cheapcast, you can cast to it as if it was a chromecast.
since putting CM11 on this device it feels and works amazing!!
-full screen immersive mode
-transparency
-snappy
-play store works perfectly
If anyone is in the UK and willing to part with their Q, I'd love to make you an offer!
Just send me a PM
