If you're thinking that you're going to have to wear those goofy paper 3D glasses to find the nearest McDonalds, that's not the case.

In the near term, it's likely that the functionality will first be available in aftermarket systems, with OEM models becoming available after the tech becomes a bit more mainstream. Actually, Clarion has been selling a 3D nav system in the UK for over a year and Sony and Panasonic have had the tech available in Japan, so it's more a matter of when, not if, the tech will be available in North America.
