If we Look up the Cruzen up on any site that offers installation criteria to allow us to remove the existing entertainment System ( OEM HU )
We will be given a List of the recommended Harness and Integration Modules for the Required Wiring for the Installation Of an AfterMarket Head Unit ..
But do we lose things, like the information display for our car? That's the $10,000 question.

It looks to me like the Maestro RR is designed to deal with that. The Maestro SW does list the Cruze - but that's just support for the steering wheel controls.

I lifted this from regarding dealer-grade scan tools:
GM MDI: This newest release GM factory interface tool begins it's coverage in model year 2010. MDI when combined with the Global Diagnostic System 2 (GDS2) software application allows servicing of GM's new Global Architecure Platform (Global A) vehicles. Model coverage currently includes 2010-2013 Buick LaCrosse, 2010-2013 Cadillac SRX, 2010-2013 Chevrolet Camaro, 2010-2013 Equinox, 2011-2013 Chevrolet Volt, 2011-2013 Chevrolet Cruze, 2010-2013 GMC Terrain and 2011 Buick Regal. By model year 2014 virtually all GM vehicles will be serviced by using the MDI/GDS application.

Now guess which of those models listed are supported by the Maestro RR? Exactly none. And the GM number of models supported become fewer and fewer as you get into the more recent years. It seems to me that Maestro hasn't cracked the newer car bus. And, as a result, they are becoming less and less relevant. You gotta wonder what's going on. Maybe time to look for another solution.
