I've tried and tried to find the anwser to this for two days now.
Basically i bought a panasonic DP600 cd changer for the misses cars it has the correct plug and sound like its hunting when i turn the stereo on, but wont work.
i pressed the mode button and turned the stereo on and it says no cdc.
i thought this was the standard changer but i cant get it to work!!!
its a 98 A3 with a concert stereo. any help would be much appreciated!

thanks
phil
