plastic stylus trim ring gps antenna speed signal extension lead reverse signal extension lead Hey As far as the parts go, the plastic stylus is useless (most people just use their fingers), gps antenna is req'd for GPS so yes get it, reverse signal lead is only needed if you have a rear view camera, speed signal extension lead is highly recommended as it increases accuracy for GPS so I would get it if I were you, and I'm not too sure what the trim ring is. Hope that helps

So I have my original nav discs that came with my D3. All they say on the discs are DVD Navigation Disc for AVIC-D3. No model numbers or anything on them. I am trying to sell them on ebay, but some people are asking if they will work with other models. When I stick the west disc in my DVD drive on my computer, the disc name is CPJ1182_x_x. Would these discs work on other Pioneer head units such as the N3 or N4, or only on the D3? Thanks in advance!\
