ok I have the alpine chm-630 I tried to get it installed this satarday when we plugged it in, the cd changer seemed to be working perfactlly, but when we pressed the cd button did nothing, as it did nothing before, It didn't say NONE or anyhthing it always just stayed on fm/am or cassate or what ever else i was on before. whats the problem!!???

 

which year/model mercedes do you have?

 

Hi Sovietbenz,
if you 've got a factory installed Headunit, you won't succeed, as the Mercedes-Benz-Headunit only supports Mercedes-Benz CD-Changers. The correct way to connect a CD-Changer is a D²B optical fibre. If you need partnumbers, let me know.

 

Some head units need to be reprogrammed to recognize a changer. I assume that you installed it correctly, because you can't install fiberless changer in fiber bused Benz.
