<< Google’s Android would allow GM customers to pair their vehicles with almost any brand of smartphone. While Android would offer GM serious competition for Ford’s popular Sync, which was recently expanded into a set of services now called MyFord, MyMercury, and MyLincoln, the Google hookup wouldn’t be an entirely parallel competitor with the Microsoft system. For example, Android could allow GM vehicle owners to open, start and/or adjust their cars and trucks, something Microsoft hasn’t done for Ford.

Google would allow better two-way communication between a smartphone and the car. Google’s operating system also would render useless GM-owned OnStar’s turn-by-turn navigation system, because Android would use its own GPS map navigation. This could be a sticking point in negotiations between Google and GM. >>
