Boss Audio Marine cd/receiver w/ detachable faceplate. At least it was detachable - when I press the open button in the lower right of the face I get nothing. It will not open no matter what. Manual shows nothing and no return mail from Boss. Unit is 2yrs old, Power is off when I try to open, and there is no cd in the unit. Can't even remove the unit from the dash unless the faceplate is off ... what am I missing?
