yes, there is no sound when the carplay unit is disconnected.

Looks almost same as mine - i didnt ground any wire - you shouldn't need to, either. Your mmi may be faulty.

I added a rear camera too and didnt even bother grounding any wire for rear camera.

If you haven't yet, try to see if anyone had this problem at this thread - https://f30.bimmerpost.com/forums/sh....php?t=1675929
