Is there to hook up a zune to a 02 Camaros stock radio without losing the ability to use my 12 Disc Cd Changer?

 

Your best bet is probably an FM transmitter.

 

Your best bet is to get an iPod Touch or iPhone. ;-)

Seriously though, get a USA Spec, it support iPod/iPhone + has RCA cables, or go for the Parrot

I think the 12-disc changer simply plugs into the back of the head unit. idk what kind of plug it is, but you could possibly just use a splitter and have one cord to the changer and an audio jack to plug into your Zune (or any MP3 player, for that matter).
