I've been searching all over the internet for days now trying to figure out what each pin on the back of the navi is used for. Specifically, I'm looking for a Video + pin, Video -(shielded), and rear camera detection pin, and if there are any grounded or 6v pins that aren't already being occupied.

Yeah i've used that guide for the whole install, except the part that confuses me is that to get video you would need at least 2 wires and he installed it using just one. Unless its an RCA I don't see how its possible to use 1 wire for video. The camera I have has a Video + and a video -(shielded). Unless pin 3 and 6 are video positive and negative and the switch he attached to a constant current so the video is always on and not just when it goes in reverse, The navi would be smart enough to only activate it when it goes in reverse. If that's the case, which one between pin 3 and 6 is video + and video -?

It makes since tho cuz all the navi is looking for is a voltage on pin 6 (or 3) and I just attach my +6v wire to a reverse light or something and attach my ground wire to a 6v source and it should work.

 

I dont / didnt know then either. When I first installed it I got nothing but a black screen. I pulled it out and flipped the connector and then It came on. Only in reverse of course.

 

I'll try that on monday, hopefully it works, Thanks for the input
