Have you checked the Chevy website for more information? Isn't there an actual manual where it goes into more detail about how to do this? Typically, you can get assistance from your dealer.
Did you read what you just typed? "advanced voice control" is ALL that says. It has nothing to do with getting your phone screen onto your car screen, etc.
FYI, this sounds a lot like Ford's (Microsoft) SYNC, which just allows you to do things like dial your phone and other rudimentary stuff, but can't get stuff on the screen. The car imports your contacts so you can browse them on the car's touchscreen, but you aren't actually doing anything with your phone at that point. Bluetooth only is what it sounds like and the actual functionality of that is very limited.
