The iPhone 12 plus will not work with carplay, but it will connect and I can talk on the phone, listen to spotify or pandora. No maps, text, and whatever else comes through carplay.

When the truck is turned off after I've driven with the phone connected, it will not connect with the phone at next start up. The F350 bluetooth connection must be removed from the iPhone and the iPhone must be completely deleted from the truck. I can reinstall, and it works (without carplay as described above) for the next drive, until turned off.

I travel for business, and the iPhone 12 has connected to a half-dozen different 2020 and 2021 vehicles and operated perfectly.

I connected the wife's iPhone 11, works perfectly. Connected an Android, worked fine.

I've attempted an update Sync 3 while connected to home Wifi, no update.

I've done the master reset multiple times, but it will not remove the original iPhone 6s plus, and it will not allow my iPhone 12 to connect to carplay or stay connected. I've scoured the internet looking for iPhone settings and have put everything where it should be.

It's got to be something simple that I'm missing...
