I contacted support before ordering and they assured me this would work with the BOSE system. It does not, not even close. Attached picture below from my 2017 COLORADO. If your connections look like this, this kit will NOT work (Until the correct harness is available). Support mailed me a harness for a 2017 SILVERADO which got me power and reverse detection, but no sound or CANBUS.

Other things to note:
-The screen doesnt fit into the molded bracket, the screen just sits on the front and requires tension from long screws (which werent provided). Tension+Thin plastic eyelets+Hot/Cold cycles, I dont have high hopes this will last. It needs about a 20mm thick rectangular spacer.
-It comes with GPS antenna, but not 4G or 5G/Wifi so you have to provide your own with SMB connectors. Even a 3-way splitter would have sufficed.
-The FM antenna cable isnt compatible with this setup, youll need a different pigtail adapter.

Still waiting for a solution as of Sep 2024

Giving 2 stars because I have been able to play with the headunit and it has some nice features that I hope to have working soon. Support has been decent. But Im still sitting on nearly $1000 of equipment with no solution.

Did not come with the correct wiring harnesses needed for my 2016 colorado
