| Your 03 CLK CD changer is fiber optic, on the back of the unit, there are 2 plugs : 1 smaller is for power, the larger with 2 ORANGE fiber cables must be insert tightly to the plug. If the CD play without sound, you may have check the fiber plug (whether you break the fiber cable while pulling it out the glove box ?). If you checking out everything OK (no breaking fiber cable), then the laser head is bad (can not read the CD), time for the new CD changer, your car (glove box CD changer location), only fit the MB # MC3010 (the MB #MC3198 also fiber optic, but it's too big for glove box location). Dealer price is very high ($600-$800), on EBAY is cheaper (may be $200-300), but the risk is : the unit may not be on a good working condition, like skip a track...), there is NO warranty on Ebay. Good luck. |
