I want to add an amp to my 06 GMC Envoy XL Denali with factory navigation. I have been searching for a wiring diagram so I can tap into the rear speakers behind the navigation head unit for the low level input on the amp but have unsuccessful. Also what wire would I connect to for the remote wire to turn the amp on/off?

You will need to find the factory subwoofer and use the wires that lead to it. Try looking in the console.

When you removed the radio, did you see the typical Yellow, Brown left rear speaker wires? And the Dark Blue Light Blue right rear wires?

You will have to find a fuse in the fuse box that has power only when the key is in the run position. Usually the Windshield Wiper fuse.
