Problem with Bluetooth PX5 - MTCD Android Head Units Q&A

Hello, i have a Xtrons model PBX79TRV PX5 and i recently installed the newest MCU version(MTCE_GS_V3.44) and Hal9k Mod v4 ROM. But now my bluetooth is not working correctly. I can Pair and start a call from the phonebook and also listen music with A2DP, but when i am in a call with someone I can not hear anything and they can not hear me. The microphone and audio output are not working. I tried to revert the MCU to the original version(I found 3.17.4), and I also tried all bluetooth drivers from the factory settings, but no success.
What can the problem be?
Here is information from my original software when i bought the device:

Which AM/FM radio app do you use on your MTCE head unit?

This is what About says for my Dicola CHS7047X:
Manufacturer: rockchip
Model number: PX5
Android version: 8.0.0
Android security patch level: October 5, 2017
Kernel version: 4.4.93+; [email protected] #121; Fri Jan 26 10:41:07 CST 2018

CPU: 8 core 64-bit CPU Coretex-A53 @ 1.5G
The one that came pre-installed is com.microntek.radio v2.4.0.
Are there any alternatives?
I'd also be interested in knowing any alternatives.
All units seem to have the same radio application installed, but since I can't root my Xtrons Oreo unit, I have no idea what radio App it actually uses.
Unfortunately searching the Google Play store, for "Radio" apps, its very difficult to find any radio apps which actually control an AM / FM radio.
Its probably a custom App.
Can you post the APK somewhere, so it can be decompiled ??
hi look for alternative application for pumpkin radio PX5, MTCE, android oreo. is there any?

Sound only coming through the front speakers

However, when I use the standard stereo that came with my Peugeot 308, the rear speakers come back to life.
Basically, it's not an issue with the left speaker or the cabling.
I have tried using the Balance app but to no avail.

Thanks four your help!
Let's bump this thread since I also have an older KLD head unit which I'd like to update. Mine runs on Android 6 and I'd like to know if an upgrade to a newer version is easily done. Also I'd like to know if I lose all button settings (on head unit and steering wheel) if I update the MCU.
