I'm looking to add a CD Changer to my 95 C220. Using the posts on this page, I found what I think is the CD cable in the trunk - but it's a 25 pin RS232 (drivers side tire well), not a 10 pin. The head unit is capable of controlling a CD changer. Is this really the CD cable, and can anyone point me to a location to find a changer? I've been to Crutchfield's and SoundDomain's sites, and they only seem to have the 10 pin adapter cables.

Thanks
