I think it needs +12v, I wired it to the yellow/white wire next on the bottom of the liftgate, right infront of the spare tire. the signal was pulsating, on/off and so forth.

it is called Pulse Modulating Wave.

you can use either latching time delayed relay, a capacitor ( i do not know the value), or run the wire to the front of the car... one of these methods will give you a nice screen...

all thats preventing me from getting it to work is a steady power source... also the navtool itself, i have it wired to a constant 12v. any locations for a switched 12v?

there are many locations in the car for a switched 12V source - where is the navtool located? what is the power draw of the navtool?

I placed the navtool on the bottom of the navigation computer. I got power from a 3 pin connector nearby which looks like the 3 pin aux connector behind the nav screen
