The Model# is 39100-SV1-A0000, Ref# is CQ-LH14102 on this unit. Right, so, it has a round plug in hole in the back that says CHG. I'm aware that I can get DIN (or nearly DIN) sized add-on cd players that'll plug into there, but those don't seem too easy to come by. Has anyone got a pinout for this? I can provide a picture/drawing of the port if that helps any. Is it a matter of jamming a few paperclips into the holes and connecting those to wires and taping it all up, or will I need a harness?

I'm trying to make it so I can connect my cd player that I have wired into the glove box (which I'd hardwired into the speakers while I was trying to get a security code for the radio, which i now have, much thanks to SOHKeg)... I'm not quite sure if this is possible though, but any help would be great.
