"Just got back from a Thanksgiving trip from New Jersey to the area around Silver Spring, MD, Reston, VA, and Washington, DC. I ran both OnCourse Navigator 5 and TomTom Navigator 5 and both had the most recent NavTeq (OCN 5) and TeleAtlas (TomTom 5) maps. Well, there was no real comparison. In that area the NavTeq maps were clearly superior to the TeleAtlas ones. Construction is pretty much a constant activity in that area of the country and so no map source will ever be completely accurate, but when you ran both of them side-by-side it was immediately obvious that OCN5 was far ahead of TomTom in the accurate display of road conditions. As much as I love to have TomTom on my Treo 650, this was one trip that I had to rely on OCN 5 for directions." --by Paul Biba
