So Sunday I rolled into our family favorite Honda dealership, and I rolled out with a 2012 Honda CR-V AWD EX-L. Didn't get the Navigational system, as per reviews it looked outdated and cheesy, and I have the Galaxy Nexus official car dock with charger coming from expansys any day now.
Paired the phone at the dealership, and was able to play some music. But the connection dropped briefly, causing music to play out of the phone. Then about 20-30 seconds later it reconnected, and a few seconds later the music played out the car speakers.
Didn't think too much of this, but I drove it home and the next day noticed the disconnect / reconnect issue was pretty consistent. And every time it happens, you can't control the Radio or do other things, cause the screens talking about the connection prevent changes. Not life or death, but certainly annoying on occasion.
Yesterday, I determined that by connected an AC Adapter to the phone, the disconnects go away and things work normally. That was a pleasant surprise, and while I don't want to take the phone out of my holster and connect it EVERY time I get in the car, at least I have a work around, right?
The odd thing is, this never happened with my Sony BT Car Deck I had in my Civic. Obviously it wasn't a stock solution, but when the volume knob on the stock deck was failing, a new stock deck was $400. I got the Sony solution for $150 installed at Circult City, and it had bluetooth which allowed me to make and take calls, stream music, etc.
The only catch I've found so far is the car seems to inquire about me transferring my contacts into the car so the phone book is available through the dash. But every time I click allow... it doesn't seem to do anything and the message shows shortly again in the "notification bar" of the phone. I'm ignoring it for now.
I did root the phone and apply the 4.04D update, then the system update saw the 4.04I update and applied that. Wondering if a factory reset might not put me back to 4.01 or something, but might not resolve this issue. Unless I have any advice, I think that's what I'll try next.
I thought about updating the baseband radio, but as I didn't install CMW or anything, pushing the radio update is a little more work that I'm ready for at the moment.
Thanks to any who took the time to look at this. Best wishes!!!
Little update. I had unlocked my phone, but hadn't properly rooted it, flashed the ROM, etc. Took me a while this morning, but I rooted it, installed CWM on the recovery partition, and then updated the radio to UGLA4.
Despite the above, the car still "drops" the BT connection about once every two minutes, and then makes the connection again about 10-20 seconds later. If the phone is plugged into the car so it has extra power, the connection stays up and reliable until it is unplugged or the car is turned off.
Not sure what to try next, if Honda doesn't have a BT update for the radio in this car. Here's hopiing!!!
FIXED!!! So here is the problem AND the solution.
Dunno why, but something about the default bluetooth.apk that is in the Galaxy Nexus, even after the 4.0.4 update was NOT working between my phone and my CR-V.
The "hint" to the fix was found here. http://forum.xda-developers.com/showpost.php?p=14249943&postcount=11
After killing this process, my connectivity issue between phone and car disappeared. But the phonebook STILL wouldn't update.
Feeling I was getting somewhere, I did searches for the BluetoothPbapService, and so forth. After some looking, I finally found THIS site. http://forum.android-rsap.com/viewtopic.php?f=33&t=221
I had unlocked my phone once, but hadn't rooted it properly. While trying to fix this issue, I'd rooted it, installed the CWM recovery menu, and tried a couple different "broadband" software packages that control the radio. That hadn't fixed the problem, but I COULD use Root Explorer with SU rights afterward.
So I downloaded the file for Android 4.0 to the Downloads folder on my GN. Then I created a new folder on the SDCard called backup. I moved the Bluetooth.apk and .odex files that were in /system/app into that directory, moved the .apk file I downloaded from that site back into /system/app, and made sure the permissions were as directed. Then I rebooted the phone.
Once down at my car, I removed ALL Bluetooth profiles from the car, clearing the BT settings completely. And then I deleted the BT profile from my phone. Then I turned on BT on the phone, pressed the phone button on the dash, and paired the phone as before. Only THIS time, the phone paired normally, didn't disconnected, and when I clicked phonebook, it seemed to do nothing as before. But a SECOND click on Phonebook, and instead of trying to download again... I GOT LETTERS to lookup names!!!!!
I tried a couple calls, and people didn't answer, but I can call and use the BT in my car normally!!! OH HAPPY DAY!!!
Took the CR-V in, got my proper plates put on, they washed the car for me (looks great!), and I ran a few errands. Having sat around doing laundry and watching Batman Begins, I wondered about getting the Media option on my Galaxy Nexus to disable like I'd tried in the past. That way, I can listen to the radio, but if I'm using my turn-by-turn directions over Google Maps, I can her Nav instructions through the phone.
I did a BUNCH of searching, and lots of people had similar issues. But one one had found a way to disable the "media" part of the Bluetooth stack. Remembering some people found that killing the PBAP process of the Bluetooth stack in Apps allowed them to sync their phone to their car, I wondered if it would help with my media issue. So I disabled it and went down to the car.
At first, there was no difference. Media went through the car, and nothing was any different. I unpaired the phone from the car, cleared the car BT setup from all devices, and started over. Once again it popped up as it always had, and I tried telling it NOT to pair every time automatically, but don't pop the HandsFreeLink message. This didn't seem to work, as the phone would disconnect and reconnect as it had in the past.
Frustrated, and ready to give up, I cleared the pairing on both sides, and went to put it back how I started. But when I cleared the car and went to pair again, I added my Galaxy Nexus, and waited for the message to come up about pairing going forward. It never came. And ironically, the car was NOT paired for media, just the phone.
Feeling brave, I connected the phone to the car with the media checkbox. It connected, and I was able to play a song through the car stereo. Figuring it wouldn't disconnect, I tried anyway... and it DID! I then turned off the phone, and off the car. Turned the phone on, the car back on, and everything KEPT working!!!
Obviously, I need a little more testing to be certain. But lt looks like I may have stumbled across a setting or something that allows me to use the phone however I wish. And that is a VERY good feeling.
Have no issues in a '12 Civic. You know, other than the recall.
Well, I'm back to having trouble.
Upgraded to Jelly Bean. Love the voice search which works great for me, the speed is still excellent, etc. But even after replacing the bluetooth stack the way I did in 4.0.4, I can't permenantly disconnect bluetooth audio for MUSIC through the phone. I've tried the usual fixes as above, and it just ALWAYS stays connected, assuming the car is on, and bluetooth on the phone is enabled.
SO FRUSTRATING, as then I can't listen to the radio AND use my turn-by-turn directions!!!
The wife and I have been troubleshooting this problem ourselves with weird results.
We purchased GNex's from Bell in Canada at the same time (yakjuux builds). About a month later, we leased a 2012 CR-V. Her phone has always had this connect/disconnect issue, while mine hasn't. We have returned her phone to both Bell and Samsung on separate occasions; all they have done is flashed it and sent it back. Of course that hasn't solved the problem. Provincial law in Newfoundland requires the use of hands-free when on the phone while driving, so this is issue is more than just an annoyance.
I got tired of waiting on Bell and Samsung Canada to get their act together with 4.1.1, and recently rooted my phone and moved it to a 4.0.4 takju build in order to get the system update. No problems with any of that, and it works with our CR-V, same as it always has. We hoped that doing the same to her phone would put this issue to bed once and for all, but after having run hers through the same process this evening, it still does the same trick of connecting and disconnecting endlessly (unless you force-stop the phonebook service, of course).
Now that both phones are rooted, I'm about to try copying my Bluetooth.apk on to her phone and seeing if that fixes anything.
flashed to the Paranoid Android ROM a few days ago. Everything was working just fine until this morning.
I use the Bluetooth in my truck using the phone and a few music apps. Spent all of my morning re-installing the ROM on a clean install. Wiped the cache and dalvik, did everything I could think of and searched for answers. Even reflashed the radios. Nuthin'
I can select the Bluetooth switch to ON but nothing happens and eventually switches back to OFF on its own.
I cannot ask questions on the specific development thread, too much noob, so hopefully someone catches this. Did my BT radio just die overnight on the charger or did something else happen?
I have some questions. (Copy from the old thread)
1. I mean that i read it here, but I'm not sure. At the moment I have very often the bug, that the volume button not works. Mute works, but louder and quieter not. I don't know when it doesn't work, but after a while no function.
2. Since a few days I have the wifi problem, that wifi works sometimes and after a while too, it shows empty bars and shows the connection but it doesn't work. In other case if I start the radio he can't find any WiFi. Why?
3. Since a few days the touchscreen doesn't work. I have set, that i can See if i touch. Then it shows a point. so i can see that the touch works, but there is no reaction. After a minuten the radio shows the bootlogo and have a loop. So i have start the radio new with reset or power off from the car.
4. Since a few days if i turn off the key normally all lights form the radio and display shut down. Additionally board computer shut down too after a few seconds. Now the light from the dvd tray is on and board computer too (after a lock from the car too). I dont know why but I don't know if that is so good (Battery).
All this errors are since a few days. I tried to do any settings but the problem is always here. Does anyone no about that? I think it's an app, but I don't know which one. The last chance (if I get no solutions) is to install another rom? That is really crazy, because it's only since a few days. The days before it works perfect.
I have JY 2.73 with the Malaysk Rom from September (1024).
Thanks
Update: Now i installed 2.59 JY and tried again. WiFi will always gone with no bars. So i turn off and turn on again. At the most cases it works. But the problem is here again. The same with the touchscreen crash. 3G doesn't work. always no bars.
So the previous MCU doesn't work again. Maybe a software error.
Could you please try to measure the voltage alignedto the HU while you encounter those problems? I rellay mean at the radio side (so not at the battery poles).
Such issues could be lack of voltage. If not and flashing does not solve it could be a defective unit.
Just to ensure: You flashed Firmware AND MCU? AM I right wit this assumption?
If not: Try to flash a new ROM first (probably try Malaysk ROM)
Btw: Moved to Q&A

Thx for answer. How can i measure that? Do you know which cable it is? And if the cable shows not the 12V? What can i do to fix the problem?
Sure. I have Malaysk Rom and the MCU JY 2.59.
you would have to get amulti- or vooltmeter and attach that between plus and ground pins at your HU.
If you don't know how you should eigther try to follow another way first if possible or ask someone to do it for you (it's electrics)

Thanks. I ordered a multilmeter. Maybe it's the battery. At the moment the car works really hard if I start it. The radio takes so much battery but the radio is off. So that can be the problem.
low voltage can cause many weird problems but you have to know a new battery might not solve your problem!
If you have low voltag while the engine is ruunning then you have a different problem. eighter there is a connection issue somewhere on the path the energy takes from battery and generator to the HU or your generator might have a problem. But that is open to check when we know if it really is a voltage issue.
Hi,
i'd like to give you an update for my problems. Since the last days I have the problems, that my car didn't start. Now we see, that the battery is nine years old. Now I charged the battery (tomorrow I'll get a new battery) and the first test shows WiFi works for 3 minutes. I know - that's not a lot, but I only can try if I have the new battery. 3G doesn't work - always the same. But that's not so important for now.
At the moment I don't have the volume error. I will test it, If i have a longer car drive.
The problem with the touchscreen is actually. Since a few time, after few minutes the touchscreen is bricked and I see the points that i touch it, but I can't click anything. If I touch ten times, twenty times or often then radio shut down and shows the boot logo... forever... it doesn't boot again. So I have to make a hard reset.
And the last point with the light board computer and the light dvd slot after plug off the key is actually too. It don't shutdown the lights on the standby time from 10 minutes (set it to 10 minutes). I know now, that I can shutdown it completely if I press the volume button for 3 seconds. Than it's turn off. So it's a setting problem from the firmware?
Today I plug in the key - nothing. Radio doesn't start. So I looked behind the radio and saw, that one thin cable is not in the wiring harness and I can see the wires on the cable. So I tried to put it in the wiring harness again. I hope it works longer now. I wrote carjoying and ask for a new wiring harness. Maybe all problems will be fixed, If i have a new.
Hello again,
now I've got a solution for the wifi problem. I've tried to connected wifi - i Known that doesn't work only few seconds and after a few seconds it shows 0 bars on wifi... now I disconnected my 3g stick and LOOK it works... full bars, no losing connection. I connect 3g again and the same problem after a few seconds.
So th3 3g stick (E1750 from Huawei) makes some problem OR the usb cable?
Huawei E355 also not working. Same connection problems with malaysk rom MTCD
Any suggestions?
Hello Guys,
I really need some insight on this problem:
I have a KLD (http://www.eonon.com/Car-GPS/Specific-Car-GPS/Mazda/GA5151.html) unit for some time now, but since September it wasn't in my car because I was preparing an audio upgrade. As one of the last steps I've checked out the HU and I wanted to upgrade to the latest MCU&FW, but the unit wouldn't turn on. Since it's on my "workbench" I've checked the cables, fuse, the external PSU, everything i could, but it did not help. The unit worked flawlessly in the car and on the workbench 2 months ago. Nothing changed. Now it won't turn on, not even the fan at the back of the unit. The screen and the button backlights are also off.
The one confusing part is, when I push the power button with reset for a few seconds, the unit comes to life, and goes into recovery! I can flash a ROM, clear the cache, etc., but when I reboot the unit from the menu, it turns off, then the button backlights flash once, but nothing else happens. The unit stays turned off.
So far I've checked:
- Fuse
- External PSU
- Power button
- Replaced the SOM (The unit is RK3066 originally, I'm using it with RK3188)
- Tried different ROMs
- Disconnected the DVD drive
Nothing helped. I can get into recovery, but I can't boot the unit, no matter what SOM (or what ROM) I use. I would really appreciate some help, because I ran out of ideas.
Thanks in advence!

Ok, the big conclusion is to use the multimeter first. Magically, ACC was not even close to 12v. Switched to another PSU, everything works.
Ok, I installed the new Joying 10.1" VW head unit in my car the other day, and it's working pretty good, however I'm having a couple of issues. I installed Malaysk's ROM onto it and still working through setting everything up the way I want it, but I'm having 2 issues I can't figure out, and they are driving me nuts.
Wifi: Whenever the unit reboots, the WiFi is disabled. I have to manually re-enable it every time.
12-Hour Time: Every time the unit reboots, the time reverts back to 24-hour time.
Anyone know what I can do to fix these issues? Getting rather annoying having to switch them every time the unit boots up.
Thanks

Sounds like the 12+ and ACC connections are swapped.
Thanks for the reply, but the unit is switched on Via Can-Bus. There is no ACC wire. It powers on and off just fine when I start and shut off the car.

Then your 12+ is not constant.
Yep it is, verified with a volt meter, 12volt constant stays hot, even went out and checked after my car had been off for over an hour just to make sure... I shouldn't have said there is no ACC wire, ACC is supplied by the Can-Bus adapter.
As far as the wiring goes, I'm confident all of that is wired correctly. I used to install car stereos as a job for 5 years, and this is the 3rd head unit in this vehicle. I'm an Android enthusiast, and definitely know my way around the system, even though this is my 1st Android head unit I've dealt with.
The 12-Hour time issue was happening before I installed the ROM on it, but the WiFi issue didn't start until after I installed the ROM.
Ok, thats a puzzler then. My observations have been that wi-fi will turn off and 24 hour set every time power is lost on the 12+ line. It seems independent of rom used, would happen on the stock rom and on a older version of Malaysk's I'm currently using.
Well, for whatever reason today the settings never reverted back. I don't remember changing anything, but I did go through every single menu and sub menu in the settings section. Oh well, fingers crossed everything stays set, because this head unit is perfect for me now!
I have the same issue + no bluetooth. I have a YINUO 1024x600 Quad-Core RK3188 and it's doing the WIFI OFF, 24 HR, NO BT.
