So my truck didn't come with the Nav so it didn't have back up camera. I purchased a factory back up camera off eBay for $40. Purchased a 12v to 5v converter from a member here (was an extra that he got it off eBay)
Factory camera

I cut off the factory plug. There were 4 wires. Red, Black, Yellow, and White.
Red = 5 volt
Black = Ground
Yellow = Positive (inside RCA) video output
White = Negative (outside RCA) video output
Wired up the 12v to 5v converter as the sticker shows, and soldered a male RCA end to the yellow and white.

I kinda went with these instructions as to dremel the rear applique
Adding a back-up camera
Outside like OEM...

and inside when I go in to reverse, or I can hit the camera button on the screen and the camera will stay on indefinitely.
