The OnStar RemoteLink app allows you to start the truck, lock/unlock doors, blow the horn & flash the lights, check fuel level, fuel range, average mpg, odometer reading, tire pressure, oil life remaining, and OnStar hads-free calling minutes remaining - all from your cell phone. You can also search for destinations using Bing maps and send them to the nav system in the truck. It also has buttons to call Onstar. GM Roadside Assistance, or your preferred dealer. It's pretty cool
