Google I/O’s shaping up to be a hell of an event this year. We just received word that OnStar will give a sneak peek at new functionalities it’s developing for its version 2.0 Chevy Volt app with the help of Google. A major new addition — to be demonstrated on Android, of course — will be a navigation tab on the app’s home screen that can identify your position relative to your Volt’s location in Google Maps. Something that should prove handy in tracking down your car in the airport parking lot. Owners can then use their smartphone to enter their destination before even entering the vehicle. When it’s time to drive, your Volt will already be setup and ready to guide you to the spot using OnStar’s turn-by-turn navigation. Alternatively, users can follow the voice guidance provided by Google Maps Navigation if they prefer. Unfortunately, these 2.0 addition won’t be in the app at launch this fall. Full press release after the break.
