When I get in my car and attach my iPhone (7 plus latest iOS 10.2.1) as soon as everything for CarPlay loads it will switch whatever I am listening to (usually a song I like on S/XM or Apple Music) over to pandora which I rarely ever use. I switch back to what I was listening to and next time I get in my car same thing. It just started doing this a few weeks ago and I was hoping it would stop but it continues to do it. Is there a way besides deleting the app that I can stop this?
