Ok im lost! can someone explain what the Navtool is and does?

 

Very Cool. Can't wait for the write-up, sir!

 

its a video coverter that uses wire that runs from navigation unit to the touch screen. at a flip of a switch or when reverse lights come on it cuts the feed from nav and replaces it with feed from camera or other video signale.

i posted most of the write up yesterday

edit: in here

 

So it injects the measuring lines onto the display using the original rear camera or is a aftermarket camera used? I understand the video function but im really interested in the "lines".

 

*it uses rca video signal, so any camera with RCA for video cable will work



think of a nav tool as a "T" in a wire

and when the "T" is activated it changes signal from one video signal to another.

 

nice, verrrry nice Roman

ok, hope I didn't miss it, but I looked over the whole posts 2x and didn't find an answer:

what camera is it?

 

What I got is in this thread
