CD changer, audio is intermittent, or unit does not operate properly. From our experience, this CD changer usually mates with the next stereo in this list. We have repaired many of these changers, they may not work when reinstalled in the car, to return to the shop and work fine. There are two problems with this system, the CD changer is bad, and a problem we have yet to determine either in the vehicle or stereo. Please do not send this CD changer for repair. We DO NOT repair ML Series Mercedes CD Changers.
