Hey Nick:

the radio is bad in this car. that error message is for the cd changer in the radio. Dealers do not repair the radios. We send then out to be repaired or order an exchange radio from an AC deloc repair center. with 39K on the car it's out of warranty so it's a repair that is going to cost you to get the radio replaced. Usually the radio's are around $250.00 + labor to replace it withc is in the area of an hour to an hour and a half labor. This issue usually happens after the battery died and the car has to be jump started or the battery was/is real weak when you start the car. Good luck :)
