This software is awesome. I have a Garmin Nuvi 350 and the Nuvi is better in most cases except for building your own maps. It is very simple to build maps for this application. Just download GoogleLeak and it goes to google maps, yahoo, etc and downloads the maps and formats them correctly all you have to do is copy them over to your SD card. This is perfect for building topo maps for backpacking, the battery also lasts a lot longer than my Nuvi. Can't beat the price, all for a grand total of $0.00.
I give it
