For no known reason at all my wifes 6 disc cd player stopped working. The car is 3 months old, it seems to have power because we can eject the CDs that were in there. Nothing is on the readout including ( security code). The security light is flashing while we drive and im not sure if it did that before, or it just did that when the car was off. I checked the 20 amp radio fuse under the hood and it fine.... any ideas???
