OnStar Telematics, a division of General Motors, is currently installed in over 6 million GM vehicles, and offers drivers a variety of connected services, including turn-by-turn navigation, automatic crash response, stolen vehicle location, and more.

Until now, the only way to get OnStar services was to buy a GM vehicle. Well, no more. OnStar unveiled a $299 standalone mirror at the Consumer Electronics Show last week that will bring OnStar's connected services to any vehicle.

Since the mirror is powered, and has integrated Bluetooth for hands-free calling, you'll need to have the mirror professionally installed. Installation is estimated to cost around $75, and subscription to OnStar's services will cost $18.95 per month, or $199 / year.

OnStar's mirror will be available exclusively at Best Buy in the Spring 2011.
