Music will not play through USB on Iphone 13 pro updated to 15.1.1
I have a 2014 Chevy Equinox LS that will not allow Bluetooth for Music streaming and only will use USB. When I connect my iPhone which is on iOS 15.1.1 to the USB port it shows as charging but does not recognize the phone itself. I have a 2018 iPad Pro that I has not been allowed to update and it is on iOS 15.0.2 that works fine when plugged in through the USB and is recognized immediately and plays. This car is not a Carplay device as GMs prior to 2014 did not have Carplay enabled radios. What do you guys recommend? I would be interested to see if I could downgrade back to 15.0.2 if the phone works with the USB. I have tried several different lightning cables with the iPhone and all do the same thing. The device is not recognized by the car in this version of the iOS!
