I have a 2013 A3 with MMI (low?), it is the smaller screen on the display. I have been able to connect my iPhone 7 via bluetooth, no issues there. However, I am unable to connect to the car via an AMI cable, the car is not registering the data connection at all, but it is charging the iPhone. Is this issue due to the fact that it is a non-OEM cable, or that more recent Apple devices will only send data using Apple approved cables? Has anyone experienced something similar?
