The CD changer in my glovebox decided it was time to die. I have managed to obtain a replacement which when plugged in seemed to work. It loaded disks and ejected disks - so far so good. Unfortunately when trying to play the disk the problem became apparent. The disk starts to play, the time on the display moves normally but - 1st second music, 2nd second silence, 3rd second music 4th second silence . . and so on. Can anyone tell me, is this because the player needs coding to the vehicle or is the replacement player also faulty?
