The announcement came earlier this month, but today’s the first day that GM’s OnStar eNav feature is fully operational. If you’ve got an OnStar-enabled GM vehicle (model year 2006 or more recent), you can search for a destination on Google Maps and have it sent directly to your car. Just like Ford Sync! And hopefully less dangerous than Google walking directions.
