Android screen Phone call routing problem
Hello,
I've recently installed this screen from aliexpress : 12.8" Car Multimedia Player For Mercedes Benz C-Class W205 GLC 2015-2019 GPS Navigation Android Radio Auto Carplay 4G 360 camera - AliExpress 34
It generally works as expected. But I'm having trouble with phone call audio routing.
Setup is as follows:
Android phone connected to cars HU for calls by BT.
Same phone connected to screen by BT for android auto, music etc.
When dialing from android auto, calls go through BT to car and eveything works like in OEM system.
When using screen's phone app, phone switches BT output to screen.
Anyone has any idea how to make it redirect call to cars audio system ?
I realize that there are two separate HFP BT devices present, but when I disable phone option on screens BT profile I lose the option to dial directly from the phone.
Looking forward to any ideas.
Cheers.
