Xtrons PB78TRVP - VW - MTCB Android Head Units Q&A

Hello everyone,
I have two questions regarding my head unit looking for your help.
I've been using the head unit XTRONS PB78TRVP for almost one year on my VW and since new I have been noticing that I am unable to control the audio volume balanced with all the apps, specially while using the radio.
The issue is that while using broadcast radio, the audio volume is too high, not balanced with the rest of the multitasking applications running in parallel.
As an example, if the audio volume while playing a radio station is set two 4, the GPS application volume when pops an audio message can't be heard as the GPS application message is very low, even if the music from the radio is temperarly muted while audio played from GPS is being heard.
This behaviour is the same independent from what GPS application is being used.
Remembering that this is happening only when using the radio as if the music is being played from an MP3 list or CD/DVD, the audi volume is balanced with the rest of the applications (including phone).
This head unit has currently installed Android 8.0. Is it possible to be upgraded?
Thanks in advanced.

Hello,
Isn't there anyone capable to help me?
Thanks

Hi. I have the same unit. Go to settings, Car setting, Factory settings and type 126 for the pin. This will take you to hidden settings where levels can be adjusted.

A2DP - Automatic Stereo Audio

I have searched around XDA and haven't found a solution to this yet.
I have a wireless transmitter to play music in my car. When I turn bluetooth on it automatically turns on 'Hands-Free' but doesn't turn on 'Stereo Audio'.
Previously on my Kaiser (with a different car kit) turning on the transmitter set it up automatically.
I have tried AutoA2DP (from http://forum.xda-developers.com/showthread.php?t=530932) but I'm not sure it worked - it certainly hasn't achieved the effect I want (although it does seem to open Media Player when I connect now).
Anyone found a solution on the TP2?
Cheers,
I did have take a quick look at my TP2, because I had no problem with the connection. My car radio (Sony Xplod) gives 2 icons... 1 from the hands-free and the other of my Audio. I've looked in my settings for you, and found one option what must be checked. It's something like: Make a seperate connection for handfree and audio! (I'm guissing to that sentence becuase I have a dutch ROM!)
Hope it helped you!

EDIT:
Just did take a closer look into my car, and now it also didn't take the extra connection with my sterio audio. This is the solution:
Go to Com Manager
Press Setting
Press Bluetooth
Take the second tab
And tap than Sterio Audio
Now He's saying he's trying to make a connection e voila! Now it's playing music true your car audio!
(This is the way with TF3D2!'

Yes - I've been doing this every time I get in my car - I just wish there was a way of doing it automatically (and then preventing the message 'You can't control audio via this headset' or similar).
Cheers,

Hi,
Same problem in my car. Same car radio working with two (Sony Ericsson) phones I used before. They always connected immediately (both 'Hands-Free' + 'Stereo Audio). Strange that the TP2 is not comfortable with this simple task. Indeed, I think the option "Connect separately to Bluetooth hands-free and stereo audio services" should be unchecked but despite this option, the TP2 is still waiting for the appropriate tap. Going to BT settings and tapping 'Stereo Audio' each and every time is frustrating and uncomfortable.
Added subscription to this topic.
I'm a bit frustrated too with the AD2P auto connect problem.
I have a Sony MEX-BT3700U Car radio.
When I sit in my car, the handsfree function connects automatically with no hassle.
But not the Stereo Audio (A2DP) function. I connect it via the Bluetooth settings. After that it works great.
The problem is I'm always focused to activate AD2P manually first before I drive and forget that I have yet to start the car. So I have to start over. Going to settings > Bluetooth Settings etc. etc. ANNOYING!
So. I tried A2DP Toggle in combination with A2DP Auto Connect. Doesn't work.
Went searching for hours... But nothing. Think it has todo with the different BT Stack compared to other HTC's.
Still hoping for a solution.
@Ramsfan_Jim: which wireless transmitter are you using? I'm thinking of buying one to use w/my TP2. My factory head unit (VW Monsoon) doesn't support bluetooth.

I originally used a Venturi Mini - which had the advantage that it automatically set up handsfree & audio transmission as soon as I turned it on, but unfortunately it broke (repeatedly) with regular use.
I now use this one http://cgi.ebay.co.uk/Car-MP3-FM-Transmitter-Bluetooth-Handfree-w-2-Remotes_W0QQitemZ250445424484QQcmdZViewItemQQptZLH_DefaultDomain_3?hash=item3a4fb5e764&_trksid=p3286.c0.m14&_trkparms=65%3A12%7C66%3A2%7C39%3A6%7C72%3A1683%7C293%3A7%7C294%3A25 which is much sturdier - and seems to have a stronger signal. However, I have to change the bluetooth settings on the TP2 to enable Stereo Audio each time I connect.
Warning - this is a much bigger device, so dependent on where your cigarette lighter is in the car, it may get in the way. I had to buy an extension lead to move it so I could use the gearstick!
Newsflash.
Found out how to auto connect to my bluetooth car radio with my TP2.
I have a radio channel bar (or whatever it's called in english) from one to six. There's a "pause/play" description small above the number five. I accidentally pressed it and it suddenly connected my phone through AD2P.
So just press play and it gets connected. So no software needed for me.
I don't use a BT car radio but I do have a stereo BT and a regular BT headset. The stereo BT has both Handsfree and A2DP profiles. But since I use the A2DP only, in my Kaiser under BT Services I unchecked the Handsfree profile and now my stereo BT autoconnects every time.
ChriX84: thanx, very interesting information, will try it tonight in my car !
Another interesting info (might be useful in terms of a .cab file preparation...): a "BT Mono" (i.e. not Stereo Audio (A2DP)) with a very low volume signal is obtained (in my car radio at least) when pressing the "Play" button on the media player (Core or WMP) while still having Stereo Audio option switched off under the BT settings.

This worked for me too. Was bugging me to the extent where I wasn't bothering streaming audio any more!
Nice tip
I always burned new mp3 cd's or connected my mp3player/phone through a aux-cable.
Bluetooth Stereo Music is a huge step forward for me. The ease of using one device for everything. Calling, playing music without any cables. Thank god for that invention.

What exactly is a radio channel bar? Do you mean like a media widget or radio widget?
Personally this a2dp bug is a deal breaker for me. I primarily use my device for audio streaming.

The bar with all the channel buttons. 1,2,3,4,5 etc.
Above or under those buttons there are little symbols with play/pause etc.

Audio Issue with Dasaita 10.2" Android 6.0 unit - Mitsubishi Lancer Evolution

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!

Audio not being muted by Nav software

hi,
hoping someone can help.
i bought a Xtrons android 7.1 unit for my Skoda Superb in ebays 20% sale after christmas.
Its stayed fairly standard so far, other than me uninstalling the original DAB app, and installing the Zoulou's excellant DAB+ App to work with my DAB dongle, since then i have install the copilot sat nav app from the app store.
my problem is that when copilot deliver voice directions, the DAB+ app isnt being muted or lowered in volume, so its getting a bit of a mess when its delivered mu;ltiple instructions or long ones when someone else is talking on the radio.
Has anyone got any ideas what might be causing that, i have gone into the xtrons setup and changed the default nav app to co-pilot, and tried changing the settings for muting the audio, but they dont seem to e making any changes.
thanks

Did it ocurred with the original DAB app?
does occur obly with DAB app, or with other apps?
Hi,
I didn't have copilot installed until after I installed dab+.
I'll try Bluetooth and normal radio in the morning and get to you.
Thanks
Hi,
I tried copilot with audio from Bluetooth and fm radio, the audio from those sources isn't muted or lowered when copilot delivers a direction.
In the android contol panel nav section I tried mixed set to 1 and 10, and separate, with no differences.
Any ideas?
I think I had problems with Copilot as well so ended up using Waze

try other Navigation software like Tomtom or Sygic or Waze if that still occurs. Try first with the option of default navigation software unselected and secondly with the specific app selected
If worked it seems a Copilot specific issue

Strange audio streaming PX3 Radio+IGO+Media player

Hello,
As far I have learned from this forum about my PX3 i don't know how my HU is managing with audio streaming. I've recently made update from Malaysk 4.1 to 5.2, but thats no ROM issue (i think) So here we go:
All options with the same system volume level!
Navigation setting in system settings set to "Mixing" and "mixing ratio" at 10 and IGO itself setting on max volume (for all the time without any changes).
1. When radio app is off and IGO navi on, prompts can be heard from all speakers loud enough.
2. When radio plays and IGO on, voice prompts can be heard from front speakers only and are quieter than radio itself. Turning radio app off, voice of IGO can be heard again from all speakers and louder.
3. With Music player on, source USB drive, music is significant quieter in compare with radio.
4. With that quieter music from USB, IGO voice becomes louder approx. double than music player, so when You listen to music on road with volume up, IGO can blast ears/mind.
The most strange thing is difference between point no1 and no2. With changes of firmware it didn't change nothing.
Any suggestions?

Android car head unit GPS voice problem

Hi Everyone!
I bought a cihnese head unit recently and all is working so far, but the navigation voice is controlled with the system sound settings, so if I turn de wolume down I also turn down the volume of the gps and I can not hear the voice of the lady / gentleman who tells me which way sould I go. I serached a lot, and found some very old (six years) solutions and new ones, but none of them work. I tried to volume up when the gps is speaking, I tried to switch Sygic to bluetooth then turn up the bt volume at the units factory settings. So as far as I know the gps navi sound and my system sound (which controlls the music loudness) is bind together and sadly the gps volume is too low. Maybe I missing something. I think this is an importatn feature, but my headunit does not have that. Can you guys give some new advices? It is an octacore android 8.0 if this matters.
Thank you in advance!
I have the same issue... Like Heptameron, I did not find any solution ! Can anyone help us with some advice?
Thanks !
Nobody ???
Same here, can't separate the two volumes.
Thought I had turned GPS voice up but then blew myself out of the window when I enabled the FM Tuner!
Spent hours on this.
"Latest" Chinese Android 10. head unit and IGO GPS. Not connected to my phone. Want it "simple" for now!
Anybody?
