Hi John,

Sorry about the delay in answering this question.  If you look at the front face of the head unit, between the ATT/power button and the volume buttons, you'll see a very small, recessed button that's meant to be pressed with a pen tip.  This is the "reset" button for the head unit, and sometimes pressing this button can clear up odd problems like the ones you're experiencing.  It will also reset all the head unit features to the factory default settings, so if you have the EQ and sound settings adjusted the way you like them, you'll need to adjust them again after you reset the deck.

Hope this helps!
