My phone pairs successfully with the Tekna audio system of my 2015 Qashqai. All of the music, radio, podcast et al apps work.
Initiating and receiving phone calls as well as WhatsApp voice calls used to work without problems since I bought the car in 2015.
A couple of months ago I received a phone call and got no sound when I pressed the answer button, I didn't hear the caller, and he/she didn't hear me either.
Since then all phone calls connect but there isn't any sound received nor transmitted.
When I break the USB connection, the call is working, but than I need to hold the phone in my hands, and that's illegal (in Belgium) and far too dangerous when driving.
Note that receiving and initiating WhatsApp voice calls continues to work.
My phone is a Nokia X20 model TA-1341 and runs Android version 13, Build nr 00WW_3_470_SP01.
I use Google's Phone app, last update apr 5, 2023, version 103.0.522355693-publicbeta
I can't think of any setting that would cause this behavior.
In fact I wonder whether it is the phone or the car that is to blame...
Any suggestions would be wholeheartedly appreciated, I am desperate as I miss all incoming phone calls: I can pick up but don't hear the caller and neither do they hear me..
