I have a 2000 s500. When I purchased the car the radio works fine. My system told me there was no cd changer. I located a broken cd changer in the trunk in the left hand fender well with a amplifier. The amplifier had a big plug with several wires attached and an orange fiber cable plugged into it and those worked. Then the MC 3198 cd changer also had a plug with 3 wires and a fiber optic cable plugged into it. However, the orange fiber optic cable(see piture below) did not go anywhere. It was just a loop that went back into itself and has a tag on it that said tele. The other oranger fiber cable that plugs into the amp goes into a wire harness. I purchased another MC3198 and plug in the power cable and the orange fiber cable that was just a loop. The system does not recognise the cd changer. I then took the orange fiber cable plugged into the amp and plugged it into the new cd changer and the system recognised the cd player, however there was no sound comingfrom the speakers niether from the cd, radio. When I plug the fiber cable back into the amp I get sound out of the speakers for the radio only. It then says there is NO CD CHANGER on the command screen. I have searched the trunk for another orange fiber cable to plug into the cd changer but none to be found. Please help.

 

Hi Raymond:

I figured it out. There was no need for a second fiber optic cable to come out of the wire harness. I had one the was lying loose in the trunk that looked like a loop. I snapped a little silver clamp up and the end of the fiber optic piece came our. So I ran it in series with the one that was hooked up and working to the amp. I plugged it into the back of the MC3198 and the system recongnised the cd changer and it works great. Sorry for all the emails and forums I have posted this nonsense to. I figured it out.

Thanks,
Gary
