Everything was working great until I upgraded to the s22. I've reset my phone countless times. Reinstalled all software and firmware you can think of. I have tried all the troubleshooting that's been recommended by the forums. As I am going through the main set-up when your phone is first plugged in to your car. After i pressed continue the phone says, that I need to refer to the car to complete the set up and my head unit it blacked out. S21 still works fine with no issues. I have a pioneer.
