As you select maps, look at the bottom of the Maps Tab to see how many map segments you have selected.

If you need help on that front, PM me.

I've done an experiment with my TOPO 2008...and VERY roughly...on average, a "map segment" is 0.5 megs...so if you multiple 900 x 0.5 you only need 450 megs of memory...i.e. one of the big 512 garmin memory sticks that already exist.

Does City Navigator or some other mapsets average out to 1 or 2 megs of memory per "map segment"? This would make a memory stick greater than 512 meg valuable. What am I missing here?????
