Garmin BC 30 WIreless Backup Camera and 2006 GMC Envoy Denali

We purchased new Garmin Nuvi 2589 and 2599 LMT devices for ourselves.  This post reviews the installation process of the BC 30 Wireless Backup Camera on my wife’s 2006 GMC Envoy Denali.

Here is the plan:

There are 2 installation methods.  Constant power, where you need to switch to backup camera when you want to use it, and backup power where the unit automatically takes over the screen when you place the transmission into reverse.  The second is preferred, and involves simply tapping into the backup light circuit on the rear of the vehicle.  The downside is that if you are pulling a trailer or just want to see what’s going on back there you cant use the camera while driving.

The solution of course is to add an in-dash switch/button to turn on the backup lights circuit while you are on the road.  This can be a good thing since it will light up the area behind the vehicle to see what is happening, but could also get you pulled over under the right circumstances.  This should prove useful when I pull a trailer and wonder what the hell is happening to the load when traffic is heavy.

Read on to see how I accomplished this feat of engineering prowess.
