Hi there
I have not used memmap, but I do use fugawi. What do you want to know?
I use it to plot caches, transfer track logs,waypoints and routes from my garmin legend. Fugawi is supposed to run through a pda connected to gps, but i don't have the cables to do this, therefore cannot say how well this works. However using it up until now, every waypoint has been spot on. Anything else you would like to know please ask. Gary
