Carplay stopped working
1. iPhone - go into Settings-CarPlay - and erase the current MB setting - reboot phone
2. on your MB - if you want to save station presets and other info - insert USB stick or SD card - go to System settings - choose Export Data and copy to that media - Remove media - then go to SYSTEM Settings - Reset to reset system to original defaults - then reboot MB (off-then-on)
3. Rebooted MB - restore settings if you have saved them - insert media - go to System Settings - Import - once complete - remove media and reboot MB
4. Connect iPhone again - it will be recognized as fresh phone CarPlay setup
This should clear this up - if CarPlay fails again you will need to see your dealer for reprogramming - there are "some" iPhones/CarPlay that have not been doing well since OS12 update
