Apple CarPlay keeps disconnecting

Random CarPlay disconnects are most often caused by the cable connection, the phone software, or the head unit software, and less often by a hardware fault.

Some steps you can try for free: use a short, certified cable, check the car's USB port for lint (a phone's own port collects lint too, which causes intermittent contact), update the phone software, and in the phone settings, forget the car and pair it again. Also check whether the problem happens in more than one USB port.

If it continues, a dealer can check whether a software update is available for the audio and navigation system on your vehicle. Updates for connectivity issues are common. If an update does not help, they can test the USB port and wiring.
