My nav stereo has this strange habit of tuning into 103.1 FM when I start the car. It doesn't seem to do it when I was last listening to the CD when I shut it off, and it seems to do this more often when I haven't driven the car for a couple of days. I'm not sure if this is related to the TP programming, but I believe that is turned off in the options. Has anybody seen anything like this before? TIA.
