2007 Denali Nav Swap

[Irish Wake]

Does anyone know if the Denali is prewired for the Navigation? It has the Bose system with rear DVD and the radio has 4 plugs in the back includung the brown connector with a green, pink, blue and one other wire.

I'm mostly wondering about the wires that go between the Nav and the Onstar box to use voice recognition. Are they already there?
Thanks

I'll answer my own question. A 2007 Denali is 100% plug and play. No need to run any additional wires, they are already there including the back up camera harness.
