CarPlay freezes and quits

Test it with another iPhone if you can. It's unlikely this is an issue with the phone, however, unless you're also having other issues with your phone.

It may also be the cable. Use the lightning cable that came with your phone or another genuine Apple cable.

If it fails in the same way with another phone, the issue is with the head unit in your car. It may be to be re-flashed or replaced.

This certainly is not typical behavior in any CarPlay compatible system I've used.

• Reset the infotainment system
• Use a different USB port or cable (or both)
• Disable any restrictions on your iPhone
• Toggle Bluetooth off and on or turn off Bluetooth entirely when in your vehicle
• Delete old Bluetooth connections no longer used
• Remove any vehicles from CarPlay settings that you no longer use or need

I've tried all these things as well. I have the same problem with my iPhone X on 2 cars - Ford Edge and Honda Civic. Seems to have started after iOS 12.2.

Symptoms include: music stops playing, and sometimes restarts; map updates freeze and sometimes resume. If CarPlay is locked up long enough (1 to 2 minutes or so), then it crashes completely and disconnects from the car's infotainment system.
