Mine cycles through the radio station favorites that I have set and when it gets to the end it goes to the next thing in the favorite list which is one of the streaming options. Once it’s in the streaming portion it will not go back to the radio with the back press, I have to manually re-select one of the radio stations on the screen.

As long as it’s on a radio favorite, I can move around back and forth through those using the steering wheel button. I am more careful now about going past the “last favorite station”, but when I do I know I can get back to it through the screen interface easy enough.
