We have a 2004 996 TT. Our CDC 4 changer died. We started getting TV, CD changer, AMP, errors on the PCM 2 headunit. Of course the MOST loop is not completed so we have no audio. We purchased a replacment CDC 4 and assumed that when we installed the unit all would be restored. The new unit appears to be dead on arrival. I'm hoping that's not the case, but afraid it may be. My questions are : There are three cables in the power connector that attaches to the CDC 4, I believe I saw somewhere that ground is through the chassis which of the three cables provides power, I'd like to connect the suspect DOA unit to an external power source to see if it's functional. (note : I verified the CDC 4 internal glass fuse was intact) Is there a fuse on the back of the PCM 2 that could have blown. I do not have the Radio code for the PCM 2 if I remove the Radio is the only way to recover a PCM 2 code via the dealer ? Would a MOST fibre loopback restore audio to the car ? Any help would be appreciated ! Thanks
