Ok, so here's the deal. I have a rooted T-mo G3 (D851) on a stock rom, out of the box it's been awesome to use with my Pioneer AVH-X2600BT head unit in my scooby. I was messing around with themes a short while ago and then the bluetooth stopped working intermittently. From what I can tell the mix-rate of the A2DP stream changes from 44k to 3hz and all you hear are beeps at multiple amplitudes. The beeps are playing out of the buffer in the head unit until it empties then it resets the connection to the phone. It still plays out these beeps until it's empty even if I disconnect the phone from the head unit.
I don't have this problem with two other iPhones. And previous to my screwing around, it'd work flawlessly since a bought it (launch day.)
Could I have screwed up a mixrate setting someplace? I do have a custom mixer xml for boosting headphone port and speaker audio but I never touched the settings for the bluetooth driver.
This behavior is intermittent and it matters very little what content I'm playing through it. I do notice that when this is happening, no metadata or control is capable through AVRCP either. (i.e. Pandora app can't connect to the phone, no album art, etc)
Sometimes it'll stop doing it and play normally for the rest of the session (drive) after a few minutes and everything is normal. Sometimes it doesn't do it at all and sometimes I can't get it work normally at all.
Here's a video showing the behavior:

Reset your Bluetooth on your headunit and pair it again with all your bluetooth devices.
I had a similar problem with my LG G3 and my Pioneer AVH-8500 where my Pioneer will not recognize my LG G3 anymore but recognizes my Note 3.
I fixed the problem by resetting my Bluetooth on my Pioneer and had to pair all my devices back to it again.
You will have to look into your Pioneer manual on how to reset your bluetooth.
Edit: I just remembered something.
Did you happen to update or change your firmware.
Some KitKat firmwares are missing the Bluetooth Metadata and will not function properly.
Use autoaudio download it from playstore. This fixes my problem on metadata
Hey thanks guys.
I reflashed the bt radio in my head unit and the problem so far has seemed to go away. Metadata and everything works again.
I appreciate the heads up from another pioneer user.

How exactly did you reflash the bt radio? I have the same head unit and am having problems with it dropping the bt connection to my G3
I just got forced to upgrade my LG G3 to Android 5.0 and it completely screwed up my Bluetooth audio connection in my car.
Bluetooth sync to home audio playback is fine, but BTooth audio is completely corrupted with the Pioneer AVH-X2600BT.
I cant find the instructions on how to reflash my stereo firmware to reset bluetooth settings. I cleared my bluetooth devices in the stereo setup, but to no avail. Can you point me to instructions on a reflash?
I am having the same issue. I have 2 other bluetooth devices that my G3 will connect to and playback is fine for as long as I have battery life. But when connected to my Pioneer AVH-x2600bt, I get constant skipping after 2 minutes of playback. I can pause it for a couple of minutes and when I start playing again it's fine for another 2 minutes. I have done a hard reset on the Pioneer and reconnected my G3 but no change. I have unpaired and cleared all of the bluetooth data in my phone and reconnected, no change. All of the Kit Kat OS devices I have still work fine with the Pioneer but none of the Lollipop devices work. I emailed Pioneer, their reply was for me to take my deck to a service center. That will do no good. One of two things needs to happen, Google needs to update their bluetooth firmware or Pioneer needs to update the firmware for the AVH-x2600bt. Until one of those two things happen I guess I'll be using stone age technology, an auxiliary cable.
Thank you, that is all.
Hello
I can't sent the music to my car radio according to the version of Android. In version 5.0 with different kernel that doesn't work, and with 5.1.1 (blisspop) it works. I 'm preferred the custom rom because I like some features. Someone have a solution or an explanation of why?
One last cry for help before I drop-kick my head unit into the lake!
Do you have an MTCB or MTCC RK3188 HU that connects via bluetooth to an android 7.1 (Nougat) smartphone and allows you to make/receive calls via the HU?
If you have, what HU ROM are you using and do you need any additional apps to make it work?
I have an MTCC RK3188 HU which worked perfectly with my Xperia Z3 for calls over bluetooth but I can't get it to work with my Xperia XZ Premium and I've tried loads of ROMS, MCUs and bluetooth/MTC service apps.
Desperate! Help! Please!
I don't have the quad core rk3188, but I have the dual core rk3066 headunit(MTCB-JY). I did sync my nougat phone (Oneplus One on CyanogenMod), and answered a phone call through the stereo. I had my mom call me to test it. She said it sounded like I was far away from the mic (using the built-in mic on the front of the HU),I was less than an arms length away from the HU. 08122014
The headunit is using the stock shipped rom with a build number of 08122014 running 4.4.4, MCU 2.16. I used the Bluetooth app that was installed on the HU to sync the phone and connect the phone to the stereo. I didn't try calling out, but I answered a call using the stereo. The phone played it's ringtone, but the stereo did a normal phone ring.
I did just update my HU using the Malaysk rom build for my stereo and updated my MCU to the highest version. I haven't tested the phone capabilities yet.
Hello, I recently installed the above Android unit into my 2014 Mitsubishi EVO with Rockford system. It came with the can bus decoder MT-SS-03 for 2014 Outlander. I set everything up in the factory settings menu but I'm having a major audio problem that sadly is ruining an otherwise awesome experience.
If I listen to any music at high volume all system audio cuts out completely for 5-10 seconds at a time. I've found this problem is directly related to the volume. The louder it is, the quicker the audio will cut out. I've double and triple checked all wiring and pins, updated to the latest MCU 2.59, Android system (8-3-2017), etc.
I'm out of ideas on what to try next but hoping someone here can shine some light on the situation. Thanks in advance and looking forward to putting an end to this issue!
I just received my new head unit from Phoenix Android Radio. I finished installing the unit but there is no sound. No audio from radio or Bluetooth. No interface beeps. Nothing. I fairly sure it has something to do with the factory amp installed in the Si but I setup the factory amp bypass. Not sure if I've missed something or did something wrong. The settings "look" right in the menus (cambus seems to be set correctly).
I have photos of my wiring setup but I can't post the links to them (I'm too new here, I guess). I'm not sure if I can post them in a reply but I could use some help. I'd appreciate any advice.
Hello all!
Edit: if you're not interested in the Story, and just want the solution, scroll to Chapter Four
This already has been quite the journey, in fact I went way deeper down this rabbit hole than I'd like to admit, so here is the story:
General info:
Car: Audi TT mk2, 2011, has Bose audio and hands free talking, previous stereo was the RNS-E
Headunit: Xtrons PB78ATTRP, PX5
So the problem was/is, the unit only outputs Sound in these apps:
-Radio, A2DP, Phone Calls, CD-Player, Music or Videos that are loaded onto the micro-SD
I contacted the Xtrons support, apart from being very unhelpful and not doing anything, I later got them to send me a new can bus-adapter (will come into play further down).
So because they weren't very helpful, and i really liked the unit, and with basically no alternatives (Xtrons units claim to be plug+play with the Bose systems, which no other manufacturer I came across claimed), I decided I'd try to hunt it down myself.
Chapter one: Updated the unit to the newest Xtrons firmware + MCU, that did nothing. Updated it to lots of different MCUs, didn't do anything either. Installed Hal9k, no change. Different MCU again, no change. Went on many searches on google, and found people with similar/same problems, but no solution. Then came across something entirely different ,but it gave me new ideas.
Chapter two: I reset the unit a few times, back to Xtrons, back to Hal9k, no change, then I came across the factory settings: you can access those in the car settings all the way down, then enter 126. Standard setting for the can bus profile was, I think, 23 AudiA3, A4. Changed it to anything different than that, and voila, sound now works like it should (although the Bose amp is now always on, when the stereo is on, giving out a little white noise). However, a new enemy emerged: now the steering wheel controls, of course, stopped working.
Chapter three: Tried many different settings in the factory-can bus settings, of course, no difference. At this point, I figured the only thing that could be wrong is either the can bus decoder box or the MCU. So I got that new box from Xtrons, and nothing changed. More internet search fopllowed: I found out some MCUs work across different manufacturers, Xtrons being "GS" for example. So I tried some different ones, and found my can bus box, being a "GS", wouldn't speak with those MCUs. At this point, I got sick of it and figured I'd learn to live without steering wheel controls.
Chapter four: a month or two after chapter three (Today), I figured why not give it another try. So I did another google research on people with can bus problems on PX5 and found this Thread.
So i did what he did, and: IT WORKS! (sort of) Now I have sound in all Apps, and working steering wheel controls. The amp is still constantly on and makes white noise when no music is playing, and i cant completely disable the can bus app, only force stop it, resulting in probably having to force stop it if it somehow starts itself or the unit reboots (if it only sleeps it's fine).
So now, I finally know where the dog was buried so to say, I guess to really fix this id need an update for that can bus-app, which probably Xtrons won't provide
I hope this helped everyone else with that problem, and I'd appreciate any ideas on how to proceed with that can bus-app
have a good one,
Hello, today is your lucky day
I have a 2010 audi ttrs and a Xtron TE706PL with Rom Hal9K ... and i have can bus original from Xtron.
The radio is a universal Xtron one, but i have buy the can bus from radio Xtron for TT Audi.
I have choose in factory the audi A3.
This is not the first android car that I ride.
I have put mcu modified GS, for better sound and it is better with the bass.

For the problem of the amp remaining simply connect the cable vag com and select "1 via remote wire", which will tin the amp with the +15 contact.
For the problem of noise parasite, just go down, with the vag com, the level of the amp, but you can if you want raise the level of the Xtron radio, I'm at -6db for the amp bose.

Hello,
By changing this option, the original bose amplifier will shut off when you turn off and take off the car key.
