not just NavTech (Score 1)

MapQuest's map data is not all from NavTech. Some is from GDT (Geographic Data Technology), who also supplies the geocoding data used by MQ (as of '99, and as far I know). Maps in large cities are generally NavTech (where it has better data), but those from more rural areas are generally from GDT. (This is in the copyright info on the lower left part of the map).
