GM’s Onstar iPhone and Android apps are now available for download completely free of charge.  If you so happen to own a compatible OnStar enabled vehicle (2011 model) you’ll be able to remotely unlock the doors, start the vehicle, activate the horn and lights to find the vehicle and contact an OnStar advisor for road side assistance or schedule an oil change.  Those who purchase the new Chevy Volt can manage the car’s charge status as well as control the charge mode.

And that’s not all.  The OnStar app will provide real time info about the car’s tire pressure, lifetime mileage, remaining oil life and view fuel information, such as miles per gallon and fuel remaining.

Lastly, the app will allow you to set a meter timer and remind you of where you parked your vehicle.  Of course the latter feature just sounds more like a simple ‘drop pin’ function found in Google Maps.  Ideally you’d be able to find your OnStar vehicle by connecting to it.
