use this thread:

http://www.internettablettalk.com/fo...mapper+terrain

and you can get the maps from each of the repositories. some may have more detail than others. you may have to play around with the different ones. for the most part, maemo-mapper is the best gps solution for the NIT, free or not.

for the most part, if you can go to maps.google.com and see what your looking for, you can see it in maemo-mapper. good luck.
