Recently bought a preowned H2 that has been vandalized. We are in the process of replacing the navigation and rearview mirror. Does anyone know if the backup camera can be wired into the factory navigation so that you can get a bigger picture? Several after market nav. units offered this option. I'm trying to avoid having to replace the navigation and purchase the higher priced rearview mirror with the backup camera display. Also the display screen on the factory rearview mirror seems small. Thanks for any advice you can offer.

 

I have a 05 h2 and the back up camera is wired in to the factory head unit. we have an 06 escalade that has the same deck with navigation and the back up camera works on it

 

I have mine wired into my factory NAV, I have a 2005. I bought a NAVTV unit that helps you wire it in as well you can hook up a second video INput and hook up the DVd player that the kids are watching in the back seats.

 

what brand and what model is ur backup cam, and what model of NAVTV do u have ... i am planning to install them

...is it possible to wire a backup camera to this vehicle's nav screen?
I would love a backup camera but if I can wire it into the existing nav screen that would be great!
Are there cameras out there made for this kind of a setup.
I just recently bought my H3 and I love it, but I am worried any time I have to back out of the drive.
Anyone done this mod?
TIA,
Craig

 

My H2 rear camera is wired to the nav screen. The camera is in the tag bracket in the center of the spare so the field of view is great. Not good for trailer hook up though. It can be done by any reputable auto a/v store or with a good working knowledge of the setup. Really is a lot better than some I've seen.

 

Where can you check it out, if you want to get one?

 

Just FYI cause I looked into this a few weeks ago myself it works like this; they have an NTSC to LCD adapter that goes between the output of your NAV unit and the screen. They then have cabling that will signal the device to switch inputs. The most common setup I saw was a dual input the the backup cam wired to the brake lights and a switch for the second av input wired to the accessory switch. If you have a rear tire holder like I do there is no perfect place to put a camera, if you don't have the rear tire the options appeared to be the middle light at the top or a license plate cam. Definitely looks like a worthy mod.

 

Here are pics of what I found behind my glove-box. I am tempted to say that this is part of some sort of backup camera system, but I can't be certain. The only thing connected id the VGA connector...and if I disconnect that the NAV screen goes dark. I'm a pretty handy kinda guy...I'm just hoping I can get an idea as to the inouts and outputs...then I can do the rest. Anyone seen anything like this before???



It almost looks like in this picture (2nd pic) that there are two video inputs for a camera, and that the "power" leads are power OUT to said camera...and the "relay" lead might be the swith-leg (linked to reverse lights, etc.)
