I have a problem with the faceplate movement on this Dual CD770 I just installed in my Jeep. When I first powered it on and went to open the faceplate to install a CD, the faceplate jammed against the dash. I had it installed too deep so when the faceplate tipped out and began to move, it jammed against the dash. I turned the unit off and manually moved the faceplate back to it's stowed position and removed the unit to adjust the installed depth. I now cannot get the faceplate to move. Is theere some way of resetting the faceplate to get it to move again? I have no manual for this unit.
