I have a Nav Lite...used...on the box itself what are the yellow, blue and black wires for? I know the red is main power lead but what about the others. I need to know a.s.a.p

 

You have a what? an Avelectronic nav lite? what is that? is it a GPS? can you find us the website?

 

Its a kit that allows video on the nav screen.

well i'm going to guess that the black is a ground

so then the other 2 are probably the video out. the 2 Rca's on the case are probably the inputs - although i am just just guessing

 

Nevermind i figured it out...yellow = ebrake so i just have to ground that. Works now. Dont know what the blue wire is for but obviously i dont need it.

 

Who knows what the blue wire is for...now its buggin me just not knowing ;\

 

OOoo i bet its the reverse line so it knows when to turn on the reverse camera. You have to wire that to the + on the reverse lights in the trunk, or find the wire that goes back there in the wire harness under the dash on the drivers side

 

I haven't done anything with mine in over a year but WikkedOne is correct. The blue wire was for connecting to the reverse line, so that the nav lite will automatically switch your display to the rear cam input when you shift into reverse gear. If you are not planning on installing a camera though, you could also just ground the blue wire to a switch and connect something else (XBox, DVR, whatever) to that rear cam input instead of a camera...though I never tried that since I wanted a camera.

On my setup, I had the reverse cam going to both the nav lite input as well as one of my DVD player's inputs, so I could switch to the rear cam even when the car isn't reversing by using the DVD player's remote control.

 

See thats what im planning on doing...just hooking up the reverse cam straight to the DVD player...since it has the inputs, might aswell use them.

 

don't know if this help:
