i'm a noob at all of this so i'm a little confused here. i already unlocked the nyc maps and everything and i tried to put it in the same directory as the default north american map and that didn't work then i tried putting it in a new folder called "map" and that didn't work either. Am I missing something here cause I already put the north american map on there with no issue at all. Btw I have a nuvi 1350t...
