I had a factory CD. Since replaced. But I had my Battery terminals off, lost time, presets, but it never asked for codes.
I don't think the factory unit asks for codes.
Might be a manual error. My owners manual and CD for 99 shows the wrong fuse box. Found other minor errors. Probably an error. Besides, who would want to take the Factory CD anyway. Without the amplifier it is worthless. With the amplifier it is still worthless....
edit: Just thought of something...do you have factory alarm....that may require a code and may be attached to radio. I vaguely recall someone having alarm problems and it was a loose radio connection...I am not sure though....anyone else?
