The system simply expands and enhances what Mercedes-Benz's system has been doing for the last few years, integrating Facebook, Google Point of Interest searches and now Google Street View into the current COMAND interface.
There's a full-scale browser controlled by the central COMAND knob, but as you can see in the video below, a combination of spotty data access (the CES show floor needs its own spectrum) and some odd user interface characteristics makes for a clunky experience.
Data issues aside, the biggest problem is using the outmoded concept of a pointer to select things on the screen. That's fine for PCs, but using a five-way controller to pan and click around a page is infuriatingly frustrating. We hope that the kinks get ironed out before mBrace2 arrives on the all-new SL and the rest of the 2013 Mercedes-Benz lineup.
