NAVTEQ and TeleAtlas both provide mapping data to GPS manufacturers, online mapping services, and generally any other application that might need street-level mapping data. The conventional wisdom has always been that NAVTEQ is "better", but more expensive, and TeleAtlas not so good, but cheaper. Here is some more specific data:
One of the most common complaints I hear about GPS navigation is "it took me on a crazy route", or "my destination wasn't even on the map!". These complaints are always the result of mapping data, and really don't have much to do with the GPS unit itself (which is why I almost never point out mapping inaccuracies in my reviews, since all GPS devices using TeleAtlas or NAVTEQ will share the same mapping deficiencies).
NAVTEQ and TeleAtlas will both always have mapping inaccuracies. However, currently NAVTEQ is the better choice (in the USA). I think it speaks well for Magellan and Garmin that they are willing to pay for NAVTEQ mapping data. Frankly, when choosing a navigation device, I can hardly think of anything more important than having current and accurate maps! Until I hear otherwise, I say NAVTEQ is the way to go.
