Well after having tested these maps, I think the whereis maps are better. Esp for the 3590. Some of the POI's on the map actually display logos of the businesses (eg various banks & petrol stations like 7 eleven, caltex, bp, etc..) on the previous whereis maps. The Navteq ones only display standard fuel, $ logos on the POI's. And the Street Name for Terrace on the whereis is displayed and pronounced properly as Terrace, unlike the Navteq abbreviated Trc and the nuvi pronouncing it as T R C.
