Stop Airpods from switching to car radio
When listening to music on my Airpods, my iPhone automatically switches to my car radio when I get into my Ford Edge. How can I stop this from happening?
Part II - if I can't stop it from happening, what is the quickest way to switch back to the Airpods? I have tried asking Siri to do this but that didn't work. I know about opening the Control Center on my iPhone, but that is cumbersome when getting in and out of the car frequently.
