This happened to me 3 days ago! I called my dealer and they said I needed to come in as it might be an "electronic issue", which was incorrect as when I got there a service tech told me this is a bug that MB is aware of. He said it's that the iPhone has so much info and the MB can't process it all. (?) Just shut down the iPhone and restart it. It worked! Good luck!This just started a few days ago. I tried using different phones, and a new wire, no luck. Any ideas short of going in to the dealer for a reset?
I am having the same issue! I have an iPhone 12. Have you had any luck with a resolution?
This worked for me, been driving me insane! Thank you for postingConnect your phone to the carplay via cable. While connected do a hard reset ( difference iPhones have various way of doing hard reset, so do a quick google search for your phone)
When doing the hard reset keep the reset buttons pressed in until you see the Apple logo appearing.
this should fix the scrambled CarPlay screen.
