I have a iPhone 5 with iOS 10.1.1. I have about a hundred songs on it that play fine through the phone but won't play in my car even though my car has Bluetooth and I receive phone calls perfectly in my car. I also have a couple of apps (pitch pipe, for example) that play find on the phone but again, won't play in my car. Do I have a setting missing somewhere? Thank you very much for your help.
