[REQ] How to start the car kit mode?

As the title says ... I ask how to start the car kit mode?
I did search for about two days and didnt get an answer, neither here or anywhere else in the world wide web.
For those of you how dont understand the difference between the car kit mode and the NaviPanel.exe ... please dont post a hyperlink to one of the countless navipanel threads. I already know the hardware suggestion by Bob but I am more interested in a software solution!
I use a parrot hands free set in my car and want to use the automatic bluetooth connection function which get started by car kit mode.
So please, If anyone knows, post a solution for it.

From my experience it's all down to how the bluetooth device anounces itself.
If it's sending out that it's a headset then your phone will connect as though it's a headset.
Go into the Bluetooth app on your phone, expand your parrot in the list and see what services it has.
My car radio is a Sony Xplod with bluetooth, it's got Stereo Audio and Hands free, but no car kit.
However if I get into the car with BT turned on on my Leo, they connect, even if I've got the Leo set to invisible.
Up until now the handsfree has connected automatically, but the Stereo Audio needed a manual push (set radio to BT audio and press "pause" button to get it to connect to phone), but I've noticed that if I go into the properties of Hands Free or Stereo Audio, I've got the option to "Connect seperately to Bluetooth hands-free and stereo audio services" which I've now disabled so hopefully tonight when I get in the car it will connect both
So, go into your BT app on your phone, check what services it has listed under the parrot device and see if CarKit is there, if it is, hold your finger on it and go to its properties to see if you can set it as default.
Chances are the parrot only presents itself as handsfree as many older phones or low end ones can't handle the CarKit service.
I'm suprised that as they're paired the phone doesn't automatically connect when you get in range of the parrot though (when you have BT turned on)

You could just create a shortcut to NaviPanel.exe which is located in Windows, and put in as a quicklink? Works for me.

The problem is not the connection. Maybe I described my request wrong. If blue tooth is already activated, the parrot and HD2 connect immediately. The problem is the always on Bluetooth function which costs a lot of battery power.
With my former device (Diamond) I used that application which started and closed bluetooth automatically while power was on USB. But with the HD2 it wont work. I dont know why!?
If car kit mode gets activated, it activates Bluetooth by itself and closes it again. So the question is again, how could the Car Kit mode be activated?!?!?

Maleko,
go back to post 1 and read very carefully. Thanks

An alternative to the hardare fix you linked is to just use your old 12v mini usb lead you have for your diamond in conjunction with a usb mini to micro adapter - I got one a motorola one for £1 on ebay.
This tricks the HD2 into thinking you have connected the 'official' car kit
I know you are looking for a software solution but why bother when you can have a hardware one for only £1!

I am not sure, that I got you right? The Diamond never had such thing like Car-Kit-Mode. So the Power cables I used were the original Mini-USB cables from HTC with the 230 Volt Charger and I used an ordinary active Bordit Mobile holder with only PIN 1 and PIN 5.
Which adapter do you mean? I am not sure, that this can work?

Ok that makes sense
My bluetooth being always on doesn't drain the battery that much faster so it's not been a problem for me.
Until someone comes up with an updated version of bluepower (looks like a good app too!) or an alternative, how about installing SPB shell 3.5?
It's got a handy button on the home screen for controlling the on/off for phone, bluetooth, wifi and airplane mode.
The trial is free for 15 days so you've got nothing to lose by trying it.
PS I've got a 12v charger for my HD2 and all it does is charge, it doesn't put the phone into carkit mode.

I know the work around soultions already. It is also possible do set a toogle button on main screen via Cookies Home Tab Editor. but that isn't what I requested. I want a full automatic function like Blue Power was

Of course, it doesn't, because for automatic activation of car-kit-mode you need that!

That is awesome!
The car USB socket charger which came with a cheap but decent cradle from ebay is a 1A charger, which I need to take apart as the end contact needs soldering back to the board inside.
I wonder if it would be easier to solder the 10K resistor to the socket rather than trying to break open the USB lead.

The problem is, that most of the car charger dont have all five pins conneced to wires in the cabel The active Brodit car holder for the Diamond for example only had a blck and red wire connected to the Mini USB port

Fantastic use of that image
I took apart my charging socket last night, and there's plenty of gubbins inside (to do with the 12v-5v conversion), but I didn't have my camera handy to take photos, or time to check which pins are bridged.
All pins are present and soldered to the board, but it could be that the wrong two are bridged, ie the two which tell the phone to accept the higher current, rather than the two which tell the phone to accept the higher current and think the car kit is connected.
I'll probably have to remove the actual USB socket from the board and re-connect it to get the right pins bridged.
Of course this presumes that the charger isn't already soldered properly as I've yet to just try it due to the end contact coming unsoldered when I got it.

So funny

Does no one knows how to start the car kit mode?

Is there really no one out there who knows how to start the car kit mode? No Hacker, Programmer oder ROM cook? I cant believe that?
Please help me with my request!!!

Here comes the solution! Thanks to Cactus for his tool!

I use Phoneweaver to do this. It detects when the power is connected without Activesysnc operating and switches bluetooth on. This is set as car mode. You can also alter other settings in this profile to change the way the phone behaves. I use this with a Parrot CK3100 and it works beautifully.

I also used Phone Weaver up to Cactus solution. It is very helpfull if you dont prefer landscape mode in car. With the activation of Car-Kit-Mode the phone gets in landscape and will be there since you deactivate Car-Kit-Mode

Best Car Stereo for most functionality with android phone

I am in the search for the best, well best for a descent price that is probably double din card stereo with the best Android integration.
By that I mean mainly blue tooth and usb.
I know based on some of the bluetooth protocols there are quite a range of things that can be integrated (http://en.wikipedia.org/wiki/Bluetooth#Bluetooth_protocol_stack)
For example pluging into USB and the deck seeing the internal memory as well as SD Card to be able to play files from it, bluetooth being able to push music to the deck as well as the deck being able to communicate with apps such as pandora to skip tracks and such from the deck.
My searches thus far have lead to me this model http://www.crutchfield.com/p_105KWHR81B/JVC-KW-HDR81BT.html?showAll=N&search=KW-HDR81BT&skipvs=T
But I know there is one more bluetooth feature I would like and that is (MAP) Message Access Profile, which allows for text related messages to the deck for text to speech functions an such. (http://reviews.cnet.com/8301-13746_...tooth-do-besides-make-calls-abcs-of-car-tech/)
So anyone have ideas, I think there are new models announced close to this time of year right?
Anyone have good suggestions for a review site?

That looks very cool but my phone is not on the list plus it seems like something that is in its infancy still. I think a broader technology like bluetooth that could be compatible with many more devices may be a better way of connecting. I think that kind of thing will be awesome in a few years when they nail down a standard for communicating audio/video to the head unit, almost like the head unit is just a monitor to the phone and a touchscreen monitor at that.

I'm actually looking for the same thing right now. I don't want to spend $500+ dollars on a head unit when I could buy a nexus tablet to do everything for half that. But I do want a stand alone radio that I can use with a phone or streaming data, plus a built in amp with preamp outs would be perfect.

App Radio 2 has many issues.

I just purchased the App Radio 2, and am returning it to Crutchfield. The screen is nice looking, but otherwise it is the single most disappointing electronic device I have ever purchased. I won't go into the long list of complaints about the device, as the hatred I now have for it could destroy a small city. Suffice to say that the unit functions as designed, but was likely designed by a team of engineers who had never seen a car, radio, phone or normal human being. There are a few threads here for people who are still trying to make the device worthwhile, with a particular success in the ARLiberator App.
I'm tempted to try that out, but the reality is the radio software itself is the problem in my opinion. It would be great to use the ARLiberator phone functions, but I don't like the firmware of the radio.
I'm looking at other options and right now the Parrot Asteroid Smart is a front-runner. I'm conflicted as it has runs Android 2.3 and I was hoping for something more current. Search around on the forum for more details on both before you purchase, there are many potential show stoppers.

hey guys,
I've been searching for a Android Head unit for a while now. I too hate the fact that most of them are 2.3, but check this unit out.
ebay.com/itm/Hot-2-Din-Car-Radio-DVD-Player-Fast-Cpu-Android-4-0-WIFI-3G-GPS-Ipod-Bluetooth-/170939816360
recently stumbled over it. Wondering if any has seen one or has one, worry about the quality. Currently, I'm also considering Parrot's new unit.
Hope this helps.

Did you buy one? I'm looking at getting one like this or something similar...

I'm currently looking for a replacement for my Clarion CX501, any updates from anyone? Seems like the APT-X support has yet to hit the headunit market.

Has no one found a good unit yet? Please update!

Get an android based double din radio, make sure its dual core, 1G Ram, DAB+ supported, 6.2-7" TFT capacitive touch screen, steering wheel controls supported and accepts WiFi dongle. you will have the mighty Google Play store to satisfy your imagination.
obviously such a unit would support most of the Bluetooth profiles.
I noticed few units on ebay but not from any known manufacturer. best i found was from some German supplier icar-tech
Alpha V800 and Alpha S600 are the ones, I haven't confirmed all the above requirements that I would wanna see in my next head unit.
Good Luck

You want Android in your car...install a tablet in the dash. That's the best option, or you could go with the Parrot. But from the reviews I've seen I wouldn't touch it with a ten foot pole.

I wanted to get in on this thread to see if anyone has actually pulled the trigger and bought something yet.
I share the same mentality -- the phone/tablet can handle most of the "smart" functions. All that's needed is rock-solid bluetooth support. If it does great USB, that's a huge bonus.
I have one of the older Pioneer stereos that first did Bluetooth. I got it around 2007. The market has matured a lot since then and I'm itching for an upgrade.

I've had a look around many different forums and stores, and I'm still at square one. I totally agree that all that's needed is rock-solid bluetooth support.

I've been into a few shops in the last few days and BT paired my GS2 running CM11 and Google Play Music with some head units....for what they can do via bluetooth, they all seem to do a decent job of it......I can skip/pause songs on either the head unti or the phone, Google Play Music on the phone updates as you switch songs on the HU.
But what it doesn't seem capable of (that I've seen or read about), which apparently iPhones can do, is change albums, browse by artist/genre, search, etc.....beyond the most basic of back/next/pause functions, unless I'm mistaken, it's just not possible when BT pairing an Android phone with any head unit on the market.
Can anyone definitively confirm that this is or is not true?

Well.... Now that android auto is in the making, maybe there will be some better offerings available for those of us looking for a good stereo!

Until then what are we supposed to do ..buy an IPhone?
I have a Google Nexus 4 and went too the effort of looking into the options. I find it utterly amazing in an Android phone you can't browse albums over bluetooth its simply a joke!
The best option would be to try to maybe get a double DIN car stereo with support some kind of screen mirroring so you can change album from the touch screen maybe something like a AVIC-F60DAB but it costs a grand would be cheaper for me to buy an IPhone!!!
I belive you need the AVRCP standard if you want the track listing to display on your headset via Bluetooth.
Even if I could get a Car Stereo to support my mobile..the big problem with the Google nexus and it seems many Android devices they don't support Bluetooth very well. There is a bug in the Nexus 4 so that when you are using bluetooth in your car stereo after a while Bluetooth will just turn off Google don't seem to care about fixing this..I don't really want to get an Apple but if means I can listen to Music via Bluetooth and get access to Google Music then why not.!!

I have a Double Din car stereo. It's the Pioneer AppRadio 3 and it works well mirroring my Nexus 5. There's an app called "AppRadio Unchained" which let's you control your phone via the touch screen of the stereo. The only downside is the lack of power on the radio which makes the scrolling not as fast as any Android phone nowadays, but the Bluetooth has been working non-stop for me.
I had to buy an HDMI dapter to make it compatible though.

I've had a look at these but they are expensive! Maybe if I get a raise I'll buy one haha!
I was hoping to get something similar, but without having to use a HDMI adapter, a completely wireless solution would be kick ass!

I was hoping to get a decent thread started for this radio as it is a great device and could use some added support from dev's.
Couple questions to kick it off if anyone is reading:
Do you guys just tether your phone to connect to the internet or is there some other way? I currently have t mobile and tethering does work but would love to automate it. There is an app called autotether but it uses Bluetooth and although this radio has Bluetooth there is no option for it in settings so I cannot seem to pair it. Would be awesome to auto tether when you get in your car though. Also, does anyone use the SD card? I bought a 32gb on amazon and formatted it to NTFS but every-time I out it in it says its in the wrong format. So I let the radio format it and hooked it and verified it is still NTFS but it will not play my media. I just tried an mkv file but no luck at all. Anyone know if the radio supports 32gb? Lastly when I use Pandora and turn the radio on and off it comes up saying no video signal. I am pretty sure this is because lack of internet but does this work for others?
Thanks for any help!
Hope we can start getting some people interested. I'm sure other owners of this device have questions as well.

If you format the card with FAT32 you should be good to go. I have a no-name 32GB that works just fine.

Hey, Gerry from YouTube here. Thanks for starting this thread. I hope this unit and units like it get some love in the future. I'd be thrilled to see some version of CyanogenMod on this thing.
Here's my video review if anyone is interested.
Ouku 6.2" Android Head Unit review

Does it have ROOT???
I just asked Gerald from the Youtube review, is this device rooted? I saw some devices on eBay that run ICS and I was wondering Ouku made their products unlocked and rooted. Thanks.
---------- Post added at 11:27 PM ---------- Previous post was at 10:36 PM ----------
And will GingerBreak work on this?

this is beyond awesome to see something in the works...at any rate just got my unit from ebay and its great just a couple questions and things to bounce off anyone that can help...
I saw that it can support Digital and Analog Tv? Im sure im just gonna realize that i ended up with the wrong one (analog one) but its worth a shot to see if it can.
I noticed I can redirect the Navi button, can we do the same for Radio ? and can I get the next and previous tracks to be more of a "global" next vs just a radio or cd?
Not that it matters but is there no "Location Settings" in the menu. I ran Google maps for the first time where it asks you to turn on Wifi Location services but i quickly hit cancel thinking i could do it later only to find out that it wasnt in the menu.
Hope this isnt too many questions, and just so i can give back to the community a tad bit...i noticed somebody on youtube was saying how he didnt have internet. I noticed that I had to set the time before i was able to access playstore, or even play pandora. Anyway hope we can fix some of these minor fixes to in my opinion one of the best head units in this pricerange to date.

From the Gingerbread manual:
"Enable location services
You must have location services turned on to view your location in Maps and to use
your location to find local resources.

My unit does not show the telephone menu on top when it boots but it does show it on top when you receive or make a phone call.
It seems that although this is Android 2.4.1 it is a somewhat stripped version of it. For example bluetooth is not in the settings nor is this location option you are looking for. I'm not sure how you would get that option to present itself again. My only suggestions would be to try another app that requires this and see if that prompts you to enable it, look for a shortcut app in the play store that does the same thing, or restore back to factory.
I for one am super happy with this radio. It does far more than any top name brand market radio available but could be that much more awesome with ICS or a non limited version of android. Would be super cool if one of the devs got one and made it happen! I mean think about it.. Android in your car, it's awesome! No more car docks, no more where do I mount my phone! Just a huge awesome touchscreen with Google maps.. Lets do this!
Hopefully someone much more advanced than I will buy one and root it so we can make this happen. :silly:

Hey Thanks, it worked well.

Compliments of Gerry and his YouTube video review, linked are the update files for this unit. These files upgrade the units MCU version from 2.8.42 to 2.10.6-1-10-1 and System from 2.12.10 to version 2.12.32. This does not update the version of Android. Honestly I don't think anyone's knows exactly what the update does but hopefully it helps performance in some way and who doesn't want to be up to date. I am not sure where Gerry received these files and I hope he does not get mad at me for posting them here. :silly:
Instructions, there is a PDF file inside or check out Gerry's video here:

Joying stereo won't link with Hondata KPro V4 via Bluetooth

Joying JY-VOS01N4GS w/ an SC-9853i 1.8GHz Octa-core, installed in a 1991 Toyota MR2 with a Honda K24A2 turbo engine swapped into it, controlled by an ECU called a Hondata KPro V4.
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/143309152617
I can install and run Hondata or RealDash apps on the stereo without issue, but I can't get it to connect to the ECU itself so I'm looking for suggestions. I've got a $20 no name tablet or a 7+ yrs old Samsung Note 3....all connect to the KPro without issue. Hondata, RealDash and Torque apps all connect without issue on the tablet or phone. New $350+ stereo...keeps giving me failed to connect error.
I'm open to rooting if needed, installing a different Bluetooth app, I have the pin to access developer options, etc....I just need it to connect and work.

It will not pair. Joying (actually FYT/SYU) crippled the bluetooth on their units. You can only pair with phones and a few OBD and TPMS BT devices.
For the rest: nothing.
And that is done onto the lowest compiled level including the MCU. Other drivers/apps/kernels/whatever will not work.

I've been writing Joying and they offered to sell me their OBDII dongle at a discount. I explained to them shortly before writing this post that the car doesn't have an OBDII port since it's a 91, lightly explained the engine sway, but I haven't heard anything yet. Why would they go through all that effort...just to force us to buy their $15 OBDII dongle?
What about universal Bluetooth dongle plugged into one of the USB cords? Or maybe even USB to USB? The ECU has a USB port that I use when I connect to my laptop to run KPro Manager (a Windows PC based program) and the RealDash app on Android does give me the option of Bluetooth, USB or serial input. I'm currently monitoring from this tablet which is completely illegible while driving, needs to be manually powered on/off and then reconnected to Bluetooth...not being able to see the gauges on a much larger screen and automatically reconnect when I start the car crushes EVERY reason why I bought this stereo. There's gotta be a way.

Wrote a long reply, stupid token expired...I'm gonna try this.
https://www.hondata.com/forum/viewtopic.php?t=18829

Bluetooth dongle didn't work, but I can't confirm if it's a dongle issue since I can connect to it but then the Hondata app says "Ignition not on" when it is. Nevertheless today I played around with the GF's cwr who has a Joying JY-HOS02P4 screen in hers, it's only 3 months old, and it'll connect to my Hondata just fine! Would it be as simple as taking the Bluetooth APK from her car and installing it on mine?

Bump for help...there's gotta be a way :/

Bumping again, hoping maybe someone can help.

Following - need this for ECUTEK bluetooth adapter in my GTR, otherwise the screen is worthless...

Like mentioned a couple of posts above. Joying crippled Bluetooth and there is simply no "normal" bluetooth stack.
You cannot alter the current BT app as it won't be signed correctly anymore and it will not even be visible anymore.
You cannot add another BT app as that will not have the correct signing either.
Your question is not new. This BT "not being able to pair" is already an issue since 2016. You would be the first to find a solution.
The only thing you can try is what I described in this post, based on info from ojuniour.
Having said that: you should also search the rest of the forum and not only stick to your own question. Otherwise you might already have tried what I described. It might work, it might not.

Surfer, thank you so much for the reply. I've read in depth and was fearful of that, but will try what is in the thread you linked. If you'd be so kind, couple questions that you may have answers to:
- I have a sofia 9853 with android 8.1 (upgrading to 9.0), does that make things better worse or same for the bluetooth situation?
- I've seen some talk on much older threads of using Comfast® CF-WU725B as an external/usb bluetooth solution? Did this (or an alternative dongle) ever or does it still work?
- I've also seen talk of used xposed modules to add bluetooth devices to the whitelist - is there any truth to this?
Surfer, thanks in advance, this is for a tesla screen in a GTR. By removing the stock screen we lose a ton of critical info that can only be gotten back through ecutek, which currently only has a bluetooth solution for android.
M5James - sorry for hijacking your thread, but hopefully this helps you as well

1. There is no Sofia 9853. There is a Intel Sofia AND an Intel SC9853i. Those are 2 different CPUs needing different ROMs.
2. No idea. Like mentioned: an external BT dongle has not worked till now, but I have never heard of that Confast one.
3. Xposed is not supported on the 9853i. Not on Android 8.1 and neither on 9.0

@surfer63, thank you again, your thread here (https://forum.xda-developers.com/an...qa-tips-info-roll-joying-fyt-sc9853i-t3979377) helped me tremendously
@m5james, on a whim i plugged in ecutek to usb via the usb mini port, and shockingly there is support for it. Maybe try the same with Hondata if there is an sort of interface on it.

Fair enough...honestly like 10 +/-yrs ago I was WAY more into custom ROMs, baking, etc etc but nowadays I feel like it's over my head again. The only reason why I asked about using other BT versions from other Joying devices is because the GF's similarily aged stereo was able to connect, but I understand the signing thing since our two stereos don't share the same OS and CPU.

Do you have a pic of how you physically hooked it up? I haven't touched much on this subject since my original post and honestly don't recall the connections at the moment but I do recall mine having a square port (I don't know it's official name) that allows me to connect via USB to a laptop. I think I even tried connecting directly to the stereo that way but no luck.
Hondata runs on the screen easily in both portrait and landscape mode but I prefer RealDash, which at doesn't like portrait mode...I'm hoping it's something I can adjust to fit myself since RealDash allows for customisable gauges.

@m5james that is a micro usb port you have, try connecting it to a usb port on the head unit (same way you would a laptop) and open your hondata app - with any luck you'll be in business. If one port doesn't work, try the other - good luck

If you guys want to use the bluetooth pairing with basically about anything then buy the "Stop" brand. Unit actually confess with 2 BT models. One for music and phone call, the other one is located in the android bluetooth setting that would enable you to pair with anything.

Junsun V1 Pro MTK8259 4GB + 64GB Android 10 headunit

Hello. I recently bought a headunit from Junsun with 4GB of RAM and 64GB storage (it seems that the other versions from Junsun do not have this SoC). Let's collect all information about this version only so we can help each other. I just installed this headunit in a Kia Ceed 2 from 2017. I did not take any screenshots of the software information, but I will add them as soon as I have them.

hi, I have rcently installed this radio on VW Golf 7. I have ine doubt because the radio looks like don't turn off when ignition is off, because when I turn on the car again, the radio start from the main screen. It means the radio don't turn off when the car is off, and on whe the ignition is on. and looks like the radio keep resting but on (with a low battery consumption).
I want the radio switch off automatically when I the igniton is off.
is it possible? do you know any option to change that?

@Balti Lopez: I am returning mine, but I checked the settings. Go to Car Settings (you should have it too), then go to Common and there should be a Sleep option set to ON. You should turn that option to OFF.

I have 2 major issues: OBD BT app is not launching for me (Junsun support said it is my adapter's fault, the same adapter that they are selling). I tried all I could. The second issue is that it does not recognize any USB stick. I found out yesterday that the USB stick I was using it dead (not sure if it is because of the headunit). Without an USB stick I would not be able to update my headunit (not that there would be an update). When I kind of snapped at them, they just said it is my problem or that I should wait for their engineer to reply. Basically I got my product on November 19-20 and the week after that was spent with me writing them.
My personal take on the software is that it is too simple. I cannot use any of the car launchers I found (like Agama) because the system apps are only available in the default launcher. It is unfortunate because I wanted an unit with 4G/LTE (mobile Internet is working very well). I was fooled that it had a lot of reviews and a lot of orders, but most were mixed. I put it in a Kia Ceed 2 and I found on a Russian forum that Junsun has been put on a blacklist because there are plenty users not happy with their products. I had some issues with the frame for my Kia, it did not fit, some users said they cut the frame (I cut one of the plastic feet).

I have bought Junsun 2/32 4G! I also have problems and I can't solve them with messages! I open dispute and they asked me to cancel it! I wonder if I would like to update firmware where I can find newer version? At settings model is 825X Pro!

Hi. I want to have Internet connection using phone data, by connecting the unit with mobile via bluetooth tethering.
I have paired phone and unit, I have enabled in unit bluetooth connectivity and I have enabled in phone settings Bluetooth tethering but I don't have Internet connection in unit. What else can I do?

Hi,
here my experience with Junsun V1 Pro with MTK 8259 (detailed spec. of device in below screenshots).

My car is:
Mazda 3, produced 2010 (type BL).
1. The radio station memory is cleared after rebooting the device (i.e. after setting differen CAN Type), so I must always to set the radio channels from beginnig on.
>> this I can handle since I don't have to play with CAN Type setting all the time.
2. I cannot pin any widget, or any shortcut of an app the to any of the home screens! The system hangs up when I trying to pin something.
>> this is to solve by different launcher. I have tried with Nova launcher and took radio, bleutooth etc. app from “for_launchers” zip file. Was working fine.
3. During using a navigation app the music from radio and sounds from navi are not mixed. Radio is playing and when navi sound comes, then radio is reduced and overplayed, I couldn't find option to change it.
>> in the end nothing special, it is a matter of expectation and taste.
4. The reverse camera (gift from Junsun) is not working afer installation according to diagrams.
>> this stays unsolved...
5. After switching car gear to reverse any backview as Warning Line or as Assistance Line are not working, not appearing!
>> is unsolved,
maybe connected with issue no 4. (system doesn't detect camera, so also deosn't activate any backview).
6. After switching car gear to reverse the sound level reduction deosn't work!
>> is unsolved,
maybe also connected with issue no 4. (system doesn't detect camera, also deosn't activate any backview, so in the end no sound level change).
7. I did Reset to Factory Settings (through android interface) to correct the problem no.2 (see description above). It helped for a moment, so after some time (~15 minutes) the issue came back, so still I cannot pin any widget or shortcut to any home screen.
8. I cannot find any option to make Screen-Lock.
>> probably dedicated app would help, but I haven't tried.
9. The CAN info are not working with my car, so I cannot see any info about open doors, etc.
>> I was using CAN Type 145, as adviced by seller, but still was not working.
All of above issue I was trying to solve with seller via messages (my english is not perfect, but their ... terrible).
After upgrading the device to a new FW (provided by seller), after few days of discussion, I have decided to return the radio back. I did all according to agreement with seller and via aliexpress system and it worked fine. I got money back (211€) , all good.
The device, beside above described issues, worked really really well, fast and smoothly.
The GPS was catch fast and 4G with sim card slot extension worked really amazing (direct internet access as well as direct phone calls possible!).
The radio reception and the sound quality, also very good!
It is a pity, because the device looks like has a big potential, but the current FW is not perfect, so causing small, but many annoying problems.
Not sure about camera issue (no.: 4+5+6), if it is connected with FW or rather with CAN decoder...
I would consider to buy it again, but first I will wait for a better FW/OS/ROM, so I am looking forward for any news about it!
I hope the info will help some of you.
Greetings!

This is the default Android behavior. Android plays by default one stream and audio streams have different priorities. Some have higher priority than others and only one can be played at one point. Whenever a higher priority sound comes, the current sound volume will be lowered for a while (any notification sound or Navi is considered to have higher priority).
For the other issues I personally blame the firmware. As I said before, their firmware is lacking and it is a shame. You had the 4G/LTE version as I did, I just did not connect the rearview camera.

I have this head unit for an AUDI and here are some things I found:
The radio and other UI components come from the system app called "MainUI" which gets modified depending on the company/seller who puts their own touches to it. It is signed using the AOSP android platform certificate and you can install/replace it with another MainUI and things mostly work. MainUI is also moddable if you know how to recompile the apk as the code is not secured in any way. Simply resign it with the platform certificate and install via adb/usb.
The unit boots up in two different ways depending on how long it has been left off.
* cold bootup which starts with the animated "android" splash- this bootup will allow apps installed to run if it has the BOOT_COMPLETED intent in its manifest.
* Quickboot- this is where the bootup is fast and bypasses normal android boot. In order to have an app start in this bootup mode, you need to set the system property, for example, to start the "navigation" as per settings:
Code:
setprop sys.qb.startapp_onresume "L#P com.ts.MainUI#A com.ts.main.navi.NaviMainActivity#T 2#I 5"
the components are seperated by "#", and the format is L#P <package>#A <activity>
then you can add optional T <number of times run>#I <number of seconds between each run>
In this example it will try to start the navigation activity twice and 5 seconds in between. I noticed that if you just try to run it once, sometimes the UI is not ready and the activity fails. The "L" at the beginning means to try to rerun apps that were already running before shutdown, it only works sometimes.
Sometimes the system properties will not stick and gets reset by the device. I do not know why this is the case. Therefore to make this more permanent change, it needs to be added to the /system/etc/prop.default file.
Changing any system files requires booting into recovery (via android developer options and adb reboot recovery), mounting the system partition and using the root access "su":
Code:
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
then mounting the system_root as rewritable
Code:
mount -o rw,remount /system_root
Someone else posted the above information in another thread and was also on the russian 4pda forums, but ill add it here as well.
Bluetooth tethering works well generally, although you will find sometimes it will disconnect by itself. In order to fix this, go to the "phone" app and reconnect from there.

Another thing I noticed was if you try to flash another rom, and get into a bootloop, there is no way to enter recovery (via the "RST" button or anything). The "RST" button as it turns out just turns off the device.
In order to fix a bootloop due to bad flash, have the "8259.bin" and "8259.upd" files in a usb disk and when the bootup says "detected", continually swipe the screen left and right. That will initiate a flash mode. This has saved me a few times already.

Changing any system files requires booting into recovery (via android developer options and adb reboot recovery), mounting the system partition and using the root access "su":
Code:
su @#zxcvbnmasdfghjklqwertyuiop1234567890,.
then mounting the system_root as rewritable
Code:
mount -o rw,remount /system_root

You can make su and remount in adb shell and /system will rw. And to adding app in quickboot is possible via edit qb_list.xml in /vendor/etc
I also modified stock launcher for mercedes and made knob working across android system as dpad.
Before change something need to make ROM backup with Flash Tool. And after that possible to get usual (not su @#...) root just via patch boot.img with Magisk and flash it back.
Also possible to hide status bar for some apps with adb command
I post some other advices at russain 4pda forum

How did you make the backup using flashtool? I tried and it said it does not recognise the system or something. Does the device have to be in fastboot mode or something?

You need to install MTK drivers and connect laptop to usb port on which carplay works. After that you should enable readback and press reset button in hole. You may try this scatter files. MTK is generated from my device, AC8257 is part of Junsun ROM. I called my scatter as MTK because Flash Tool doesnt know AC chipsets. My device is 4/64 gb, another probably 2/32 gb

Hi, I have this same radio. I tried to connect it to the computer as I read here and I could not do it. What I would like to do is to root it and if I can put the TWRP RECOVERY. I have not been able to extract the boot.img from the firmware.bin. On the other hand, the "back" button has been deconfigured and now the action it does when I press it, is that I turn off the screen. Do you know how to fix it? I have used the "BUTTONS REMAPPER" application but I have not achieved anything.
Best Regards

Sorry, repeat.
