does anyone have some info on the clarion system in the 2008 cyclone 4012...we just bought a used one, and can not get sound if i put anything in the dvd or cd. we think we need to take it out. possibly there is a stuck cd in there (we get some spanish music that we cant figure out where it comes from)..spoke to a guy at heartland who is pretty sure it is a multiple changer..i can put in a cd and eject it but only eject the cd i installed.nothing else...shows it is a clarion dxz465mp on the tuner one..and another faceplate where you insert the cd's with no numbers. any help would be appreciated. would like to watch dv's when we travel.. thanks. diana any wiring diagrams or anything would be sweet
