After latest system update my screen randomly distorts whatever is being displayed via CarPlay.  Eg Spotify, Waze etc.  To get it back to normal, I need to leave the CarPlay screen and go back in again, and it’s fine for a few minutes.  Only happens to the Car Play screen- the main system Home screen is unaffected. Any help/advice gratefully received.   

Have you rebooted your phone?

You are not the only one. I have the same issue, also a few others that I know. I have updated the phone, updated google maps for a few times and nothing helps. Phone is iPhone 11 pro. Some have suggested to delete the phone from the car and connect it again. I didn't try that yet.

 

Are you sure it started after car system update? Because I don't remember having any car updates in the last few months and the issue with car play started only recently.

Mine did similar thing after that little update that was barely noticeable. Some systems went screwy too like ACC. Forced a reboot of head unit and all back to normal (long press on )

Car system reboot also doesn't help.

From my experience CarPlay issues only arise when using Google Maps or Waze. Spotify, Apple Music, Apple Maps, etc all work fine, all easily controlled by Siri. Soon after loading either Google Maps or Waze problems begin either with the display or functionality (like G. Maps finding a route but to actually able to start the route guidance, either by voice or tap the screen).

 

Conspiracy theorists reckon its a ploy to make CarPlay look unreliable…

i can confirm issue appears  only when using gmaps. Youtube for example never causes any issues.
