Turned on my GPS today and got a message saying memory almost full. So, started looking through all the trails I've accumulated over the years to see which ones could be dumped.

After going through about 5 route previews on a 3 inch screen I decided there has to be a better way. Currently running Lowrance ifinder H20 if that helps and looking at there site I can purchase some mapping software, but there has to be something free out there.

Anybody got some suggestions on mapping software that I can use to download my maps to and review?
Also, I would i pull them off the internal storage onto a memory card?
