Even though the stand-alone OnStar system isn’t tied into your car’s electronic system for crash response, an accelerometer in the mirror will trigger a crash response if the car comes to a sudden stop similar to that of a front, rear or side collision. This likely won’t be as accurate as the system equipped in GM vehicles, but there is a red cross-emblazoned button on the mirror that drivers can press to call the service.
The blue OnStar button is there, too, to dial up turn-by-turn navigation, roadside assistance and hands-free calling. You can buy minutes from OnStar and use the mirror as your phone, assisted by an operator. Or you can use the mirror’s built-in Bluetooth to pair with your cell phone; a microphone and a speaker are in the mirror.
We wonder if competing manufacturers or their dealers will start offering the mirror as a dealer-installed option. Let us know what you think. Would you be more interested in the OnStar service if it were available in any car?
