anyone know of any aftermatket headunits that will work with the factory 6 disc changers? Or know where I can get wiring to connect the changer to a new unit? I hate to get rid of it because its a good unit, has never skipped once on me. I feel that its really worthless to scrap it and go buy another whne this one works fine. I'm assuming that the radio units are made by Sony since it looks like their design. Any help would be great. thanks.
