Hey guys,

I am hoping someone has seen this before. My 2000 S430 Comand system produces no audio and displays "no cd changer". I am pretty good at troubleshooting most mechanical things but with the D2B system on this car I have no idea where to begin. I did test the amp for 12 volt across the fuse and the COMAND sytem fuctions as normal - just without sound. Does anyone have any ideas on where I might start looking?

Thanks!

Brian
