After recent update my CarPlay does not work anymore. Any suggestions

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

• Press and quickly release Volume UP button
• Press and quickly release Volume DOWN button
• Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF).

same issue iphone 13. updated to 15.6.1. i attempted: force reboot, forget device on phone, forget device on car, nothing worked so far. wired carplay works, tho.

Do the Force ReStart procedure again on your iPhone again. Furthermore, is your iPhone 12 Pro Max fully updated to iOS version 15.6.1 ? If NOT then please update your iPhone and then try CarPlay again in your car(s).

You are welcome. Glad you have the issue resolved.
