k, first off... if you start the car/insert with tuner mode already setup, if you do a longpress-knob to switch sources, if you're in track view, there wont be any dot to signify where you are in the song. second, if you have set a1=AM station, and a2=FM station, doing a longpress-knob to switch to tuner will always result in the FM station being played, even though i was previously listening to the AM station.
