I have a MTCM KGL5 v2.55 android 4.4.4 headunit and the radio and gps sound first became scratchy and distorted but now has stopped working. If it is cold it will be scrstch and distorted but off if warm. The dvd, bluetooth. Sound is just fine. Anybody have any idea what is wrong andhow to correct. Help appreciated.
That is supposed to read mtcb and my antenna ground inside is well connected so that is not the issue.
I went into the factory settings and in the audio section. I set the radio to 1 from the original 16 and now the radio plays well.

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?
Hi All,
I have recently experienced an issue where the sound has stopped working (not going through car speakers) when in music, video or navigation app.
This used to work perfectly.
Sound works normally when CD inserted
Sound works normally when using radio app.
Video app plays video - but no sound.
Music app plays the mp3 tracks - but no sound - can see the progress bar moving along (music (mp3) on SD card - 8GB formatted FAT32)
Also have issue with the BlueTooth - connects to phone but seems to be around wrong way - it appears the head unit thinks it is in phone handset mode when it is not - as result can hear people talking through the car speakers but they cannot hear me unless i toggle handset mode, but then people can hear me talking, but i cannot hear them...
I suspect for whatever reason the audio out is being directed to Blue tooth or whatever
Has anyone else come across this issue, and if so is there a solution?

Have you tried making your phone and the head unit forget each other?

Yes I have - same result
Have also tried
- resetting unit - factory reset
- pulling the power on unit for
Whatever the issue it appears to be persistent between boots....
Now there is another issue - won't display the feed from the reversing camera
The head unit switches into camera mode, but displays message "No Signal"

To offer you the best customer service, we will send you the return address for full refund of your order.
I also have a Pumpkin KD-C0224 head unit and it works really great, does way more than you need it to do. (http://www.amazon.co.uk/Pumpkin-Capacitive-Multi-touch-Navigation-Multimedia-y/dp/B00OB90SOY/)
1. About the sound issue, perhaps there is something wrong inside of the unit.
2. About the Bluetooth, you can try settings-》backup&reset, then do the “factory data reset to see if it can help.
3.About the "No Signal", I have encountered this issue and Pumpkin sent a video instruction http://www.youtube.com/watch?v=lu8maRNrtlk
PS:You can ask for help from Pumpkin and customer service has been very good.
Android 4.4.4 Car Unit S07 sound problem
Hi to all,
I have a similar problem. My device is a Universal 2-DIN, Model: S07
Lately I had a problem with sound coming from sd-card. The quality of sound was good enough for some time and few minutes later, the sound coming only from one speaker, then transfered to another speaker then the listening becomes very bad and suddenly comes back very good as in the beggining.
That was in the past because now there is no sound at all.
More specific:
I have sound in Bluetooth, CD-DVD, Radio and the touching clicks (on device).
No sound at all from the device such as NAVI apps, in 2 sd-card slots and 3 USB's (2 back, 1 front). Of course I see video but without sound and the music plays mp3 once more without sound
I have already done the following:
I opened the device, unplug and plug-in again all the ribbon cables. Factory reset in Android 4.4.4, upgrade to 5.1 lollipop with reset to factory settings again, and finaly downgrade back to Android 4.4.4 with reset to factory settings again. The problem is still the same.
Is it damaged ribbon cable ? or other hardware problem ? because I don't think that is a software problem. Any opinion is helpfull.
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!
Hi guys, hoping you can assist...I've had an Xtrons unit installed in my Audi TT for about a year now. One day as I was driving, I was listening to music from my phone via A2DP. Midway I switched my phone to my bluetooth headphones so I could listen on those in one ear. It seems the phone stayed paired to the head unit but the music was coming through the earpiece fine, no sound off the headunit.
Ever since that day, I've had no sound coming out of the head unit at all. I've done a factory reset, unpaired any bluetooth devices, and just tried listening to radio, but no sound comes out at all. I thought maybe the amp fuse was blown so checked that and it isnt that. I've pulled the unit forward and no cables are loose
I've contacted Xtrons to try and see if there's a new firmware in the hope that will fix it. My current build is shown below.
px5-userdebug 8.0.0 OPR5.170623.007 eng.hct.20181206.171300 test-keys
Has anyone else experienced this? I'm hoping its a software issue and something didnt blow inside the unit itself. Everything else works fine, just no sound
Here you are a complete repository for mtcd units.
Select px5 and android 8 (oreo). Select any manufacturer (all rom are compatible)

Hi everyone. I ask you for help because I am a GOLF 5 owner with an Eonon GA5153F installed (which should be an MCTB) originally with Android 4.4.4 which I then brought to version 5.1 with a rom
The problem he has always had is related to the audio quality in calls. Until I used it, I used the hands-free phone and that's it, but now that my wife uses it, I prefer to be careful while driving and therefore call and do everything via the car radio. The problem is that the audio I get is really HORRIBLE. Practically whoever is on the other side of the phone hears nothing, hears 1 word every 5 and at a very low volume (I've already gone to the factory settings and turned up the bluetooth but nothing changes).
I've read that many of these Chinese have made hardware changes, removing the capacitor and resistor on the bluetooth module or similar, but I can't find anything about my car radio. Have any of you done this? Does anyone of you have photos, videos or something that tells me on mine which component I have to desolder, which track to open, or what to do?
Please because the quality that this car radio has on call is really a shameful thing!
Thanks a lot to everyone
P.S. Currently I have connected (in the back of the car stereo) an external microphone (the one that was inside the car stereo package)
