Well, I didn’t go with a wireless model and my 2010 4x4 WT/LS does not come with a head that has a screen and I didn’t want a separate monitor to hang on the glass or mount to the dash so I went with the camera and rear view mirror screen. I purchased the Auto-Vox T9 which is an older model but I didn’t know that when I got it off Amazon for about $110.
The thing that I did differently was to skip mounting the camera to my license plate or on the bumper somewhere and actually purchased a tail gate bezel ready to accept a camera. I rigged in the Auto-Vox camera which is NOT exactly like a stock factory GM camera by enlarging the square hole in the bezel slightly to allow for a little more of a tilt due to the fact that the camera does not have the same spread angle as the factory. If you use the slot as is, the camera shoots down too much.
Running the wires was pretty ez, camera had one cable/plug and a red wire to tap into the back up light circuit the rest ran towards the cab. I ran the cable inside a 3/8” black plastic corrugated tube jacket because it was going to be exposed under the truck. I followed the trucks main jacket of wires towards the cab/eng. compartment and zip tied to it.
When I got under the cab, I found a rubber grommet under the drivers seat and I poked a little hole and ran my cable though and up under the floor covering.
From there I routed the cabling towards the plastic trim that is next to the e- brake lever then up and into the fuse compartment to the left of the dash.
I had to run a separate wire that I added to the red wire for ignition on power that comes with the cable. I did this because I had to run to the fuse box under the hood.
There was no ignition power on fuse inside the cab that I could find. Running that additional power length of wire through the firewall was the hardest part of the install for me.
I like the whole system except for two issues that I have.
One is that the glare that I get from having a regular cab with no tinted windows is so harsh that it makes it hard to see the video playing on the screen even if I try to adjust the contrast. I think if I create a hood or cover that I can mount over the top of the rear view mirror I think that I would be able to see the image better.
Second thing is that if you don’t run the video all the time which I have mine set up to shut off after five minutes and if you use the so called mirror reflection, it’s not that great. It’s ok and I’ve gotten used to it but it’s not bright not like a true mirror.
Oh, I forgot, if you rely on back up grid lines, the T9 has them but they are a pain in the arse to adjust and set up as you like.
There are a couple of videos on YT that show this model in action if you’re interested.
Have fun selecting and installing.
