iPhone 11 always starts playing iTunes over bluetooth
I have two cars, and both have Bluetooth radios in the dash. I also drive a car at work (and it, also, has a Bluetooth-capable radio in the dash).
Whenever I get into ANY of these cars, iTunes will start playing over Bluetooth (when the Bluetooth is select on the in-dash radio).
I am using iOS 14.7.1 on my iPhone 11.
Where is the setting to disable this, AS IT IS DRIVING ME NUTS!!!!!!!
