Mercedes North American R&D head Johann Jungwirth snaps a photo of our reporter testing out the automaker’s Google Glass integration.I put the car in park, unplug the phone, and put Google Glass on my face. Within seconds, I’ve got step-by-step directions to a coffee shop down the street beamed directly to my eyeballs. This is what Mercedes-Benz has planned for the future, and not only do they have a functioning prototype, they’re working with Google to make it a reality. It’s called “Door-to-Door Navigation,” and it’s just the latest in a string of high-tech pushes the automaker has made in the past few years. It started with Mercedes doubling its resources and employees at its Silicon Valley research center, which allowed the automaker to work on a thoroughly revised infotainment platform and develop one of the first comprehensive integrations of Apple’s iPhone into its entry level and youth-focused CLA.“We definitely see wearable devices as another trend in the industry that is important to us,” says Johann Jungwirth, Mercedes’ North American R&D President & CEO. “We have been working with Glass for roughly six months and meeting with the Google Glass team regularly.” And it’s helpful that Google HQ is just a 10-minute drive from the automaker’s Palo Alto research facility.
