Memory-Map is slow as a hard shit.
Very annoying application to use. Try to use the 100K Topo or 25K topo maps with Memory-Map and come speak with me again after that. I wouldn't recommend Memory Maps. 5 pukes on the rating scale is more appropriate.
* Mud Maps (expensive) but more usable.
* GPS Kit is also worth a mention.
