The free OnStar RemoteLink app is now available in the Store for Windows Phone 7.5 and 8. The app lets GM owners check the tire pressure and the oil and fuel levels (something drivers do more than a half million times a month with the app). And if you lock yourself out, RemoteLink can pop the lock for you or start the car. The app requires an OnStar subscription and works with any 2010 or newer Cadillac, Chevrolet, Buick, or GMC vehicle. Download it now.
