Road Top CarPlay Issue
I added the Road Top CarPlay kit and am finding that if I am connected to both the car's BT and the Road Top BT and have an incoming call while in CarPlay mode, the caller can hear me but I cannot hear the caller. When checking the connection on my phone for the call, it is defaulted to CarPlay. I must switch to the car's BT to hear the caller through my speakers. If I "forget" the car within my list of BT devices on my iPhone, everything works well when receiving a call. If I add the car back in to the BT list, it messes up again. Road Top's solution is to delete the car from my iPhone list of BT devices. But, if I happen to be switched to the factory COMAND mode, I lose the hands-free calling feature unless I switch back to the CarPlay system.
This is something I can live with since the only reason to have my iPhone connected to the car is for hands-free calling anyway (and I guess BT audio which I have never used in the factory mode). If I could configure the connection priority to be the car for all calls, that would be perfect. But I haven't been able to figure that out.

Apparently, after reading other posts after searching "Road Top CarPlay", this "issue" is a long-standing one and the fix is to disconnect (forget) the car's BT connection. Not sure if it is an issue or a "feature" of BT.
