A couple of years ago the two days after an update, my car was jumping to different stations. But the stations were all Favorites. Each time I got in the car it would move to another. Well, while its nice to have Favorites selected, I only listen to one 99% of the time, so I cheated the media player. I removed all the Favorites so there was only one selected. It could not jump to another. A couple days later, I selected two previous Favorites and pinned them. The problem had solved itself. Why? How? Got no idea.
