Until last week, when changing to another saved/pre-set SiriusXM station on the MIB3, songs would start playing from the beginning (or up to ~2 seconds before the beginning). I believe this feature is called "Tune Start." It stopped doing this. Now when I change to another station, whatever song is playing is at the point where the "live" broadcast (i.e., no longer starting at the beginning of the song). I have been unsuccessful in finding any settings or guides on how to reactivate this feature. Any suggestions?
