My head-unit all of a sudden while I was driving listening to music set at a very low volume, flipped down (but not back so that the black part was showing) and turned the power off on itself. When I detach the faceplate it flips back like is when car is on. When I reattach the unit it just flips back down in the insert CD position. (I have a CD in the unit atm). Tryed reset button and no dice. Anyone?
