Just installed an AVIC Z2 this weekend. I had to check out the other topics to find the VSS wire. I found it on this thread, they also talk about using the factory camera on an aftermarket head unit. I may do it in the future because the nav screen is soooo much bigger than the screen that Toyota gives you. I am also thinking about installing a second camera in the grille so that I can get a better idea where the front corners of the truck are. Eh, when I get around to it.
