i have a jap import car and don't realy care about hte radio but i put a sony cd changer on it with a pre-wired harness and the head sees the changer but won't play any disks do i need to do any set up tweeking or anything sorry for being thick but i work with computers everything is just plug n play lol
Do you know the model number of both the Head Unit and the CD changer? It would be helpful for us to look up what wiring you have and consider how you wired it, or even if you HU can support a cd changer setup as you have it? Lots of determinations, please post the Model numbers
