My 2008 GTS shows the date one day later than current (it is showing today as the 25th but it is the 24th). I see the place in the PCM menu to theoretically change it, but there is no actual place to do this. I can change the date format but not the date. Anyone have any ideas? The owner's manual shows exactly what is on the PCM display, so I don't think that I am missing something.
