With my current vehicle I have had a iPhone XS and IPhone 13P neither had any issues with my vehicle.
Connect to Bluetooth and drive on.
I have a launch iPhone 15P and since day 1 I’ve had issues with it just randomly disconnecting.
Connects back no problem.
Phone isn’t in a case. Connects to my watch zero issues.
Any ideas?
