I have a 2002 C4S. . .is there a simple way to tell if it is a MOST bus, or if its a regular analog (albeit Bose) system?

 

Sorry, I can't answer the question, but I love the avitar pic! I'm in CLT, too. Looks like you're somewhere over near Gateway Ctr in the pic, that right?

 

Yup, I used to live in Gateway (I bought a place in 4th Ward about 6 blocks from Gateway) but the top of the Gateway garage has a great view.

 

I *think* that it's the '03 models onwards that use MOST....ie CDR23 Becker stereos...I've got a CDR-22 (aka as a CD-22 in the US) which is definately ISO, not CAN Bus...have a search on PistonHeads, there's quite a few queries about stereos (incl loads from me, I'm afraid!)
