I decided to take on the task of removing my Shaker 500 radio. Removal went fairly easy(didnt break anything yet)... Took the cover off the cd player and removed 3 discs that had been lodged into the unit. However after I hooked it all back up I can see the arm moving but it is still giving me the same error and says "CD ERROR and ALL SLOTS FULL". Can anyone please tell me what I can do. Unhooking the battery has already been attempted thus me Unhooking the actual power harness from back of the unit. I know from my research that most the times you have to send it in to the dealer or buy a new unit. Just thought I would ask if anyone knew any tricks. Thanks Guys.... 2005 Ford Mustang GT Premium 5Speed.
