I just got an N3 in that I ordered from ebay. The only thing is all I got was the brain, HU, GPS wire, brain to navi wire, and the antenna wire. I need to know what other wiring harnesses I'm going to need to get before I install it.

thanks for all the help.

Well to begin you will need the Wire harness that connects to the AVIC (Comes in the box with the AVIC). Then you will need a Wire harness for your specific car model and year (You will need to order or get from a local installer) and you might need the faceplate for you car (Installation Kit).

You'll also need the rca harness. Probably the cage, and brackets too.

I have the cage and brackets as well.

so it looks like the harness for my car, the power harness for the avic and the speaker harness too??
