NAVTEQ 3D Map Data

Hi,

Anyone use 3D Map data from Navteq for their application? The Navteq Website claims they have data available in Collada but I don't see any information on how you can actually USE the data. The 3D Enhanced City maps are impressive . . it would be great to be able to tap into this stuff.

Any guidance/suggestion appreciated.

I also am trying to figure out how to import realistic map data into unity. Anyone know of any sources or best ways to handle this with unity?
