Mercedes-Benz and Google are working on a new type of door-to-door navigation using Google Glass. But this would not serve as your regular navigation system it will literally give you turn by turn directions to your destination even after you park your car.

It would work by putting your destinations address into Glass at home, that information then transfers to your in car navigation once you plug your phone into your car. Once you get to your desired location and out of the car the navigation will return to Glass so you can complete your journey. The difference between this and Google Maps is that you would be able to seamlessly switch between both Glass and the Mercedes app for your vehicle. Mercedes is already working on a prototype of the technology and hopes for it to be available to the public sometime in 2014.
