So I have a full CD changer and the car was in the wife's hands and by the time I got it back, she had switched it to FM and when I switched it back to CD, I got a CHECK CD message, followed by a CD OUT message and nothing. I tried to switch discs, but got nowhere. More CD OUT messages. Tried to eject and just CD OUT messages. Any clue what happened to the changer? Should I repair or rip it out?
