Wiring Diagram and Harness Needed

[Trailblazer 2004]

I have a GMX222BTNAV1 (DELPHI 25801749, GM 25801749) NAV radio. Can this radio be installed in my Chevy 2004 Trailblazer?

If so, is there a wire harness for it that will make it work? How can I acquire a wiring diagram of the 4 connections on the back of the unit?

The radio of off a Buick Lucerne.

Along with the correct kit I would think so, look on eBay for wiring harness for your vehicle and din kit matching the radio you plan to install right ?
