Hi, I just got a Avic-D1 w/o the harnesses, and I'm testing it out to make sure everything works. The problem I'm having is for some reason, the navi disc won't eject. Since I don't have the harnesses, I have the 12 volt, acc, and ground wires connected to a computer power supply right now. Is there something wrong with the headunit, or do I need to attach another wire? Also, does the parking brake wire use ground of +12?
Also, does anyone know where I can get navi discs without having to spend $250 for a set from Pioneer?
Thanks in advance.
