The cd player has been kicking ass for 15 yrs now. Even though I have lots of aftermarket equip., this stereo sounded so good I decided to leave it in. All I had to do was add a sub and it was cranking! Recently the cd player stopped working. Only the eject function worked, displayed the time and shut down completely. I replaced it with a cd player I yanked from a PT Cruiser with matching part no.'s. It behaves the same way. I was told that the problem could be with the truck itself and maybe the external amp is the culprit, if I even have one??? Can anyone shed some lite on this issue? Thanx either way!
