iOS 15.2 on iPhone 12
Just bought Audi Q8 2021 and was trying to connect car play to use google maps on my iPhone 12 pro.
After two days of frustration went to Audi dealer and technician there told me that iPhones 12 and 13 cannot be connected. On his iPhone 11 he had the same iOS 15.2 but his phone was recognised by my car right away. Maybe new iOS 15.3 will fix this problem.
