Back up Camera Re-WIRE?

I have a 2013 Limited Toyota Tacoma. Is there a way to re-wire my back up camera so that it will show on my navigation screen instead of just the rear view mirror, when I reverse ? Any tips please let me know thanks!

 

Its possible, just trying to find out how to do it. I know there is a harness that plugs into the back of the head unit but I have not figured out where to locate the wire to the rear view camera to tie into. These guys do it but wont tell how! http://youtu.be/h-6RGtybtUU

 

I know there's a write-up on here somewhere...

 

I've looked. I found two threads but no clear answers other than buy an adapter from nav-tv.

 

I thought it was one or the other? I actually want it to show up on my rear view, but it only displays on my Nav...

 

I think it's as easy as locating the video feed wire in the mirror harness, and tapping an RCA cable into it, then running the other end of the RCA to your head unit's camera plug. If you are talking about the factory navi, I'm not sure which wire is the video feed. I know on my Pioneer F700BT there is a clearly marked female RCA for the camera wire to go to.
