Looking to install a back up camera in my 2011 Sierra 1500 SLE

You can get a Pioneer Display System, Some come with Cameras some just have hookups for it, and any basic 20$ camera will do, you can mount it to the truck, to the licnese plate frame e.t.c and it will turn on when you shift into reverse.

I bought a wireless that replaces my mirror. Works well for parking and backing up to trailers
