Roadnav does support the open map standard, which means that it can be used internationally if there is coverage.
The open map standard, OSM project, is still very much in its early days.

Whilst a lot of the busier roads in Europe are covered they are still not 100%, indeed in some instances far from it. Map data that is recovered as part of a business process by Navteq and Tele Atlas naturally has to be paid for, by us and our users, but the detail and coverage is higher.
TIGER data is detailed but IMHO is nowhere at the level that Tele Atlas and Navteq supply, especially when you take into account all the extra features they add on.
Long term, as the OSM project grows, then we'd expect some changes to take place. Of course how to deal with the licensing model is another hurdle! ;-)
