I'm looking at the GPS again. The Monterra review seem to be expensive and terrible. The Montana appears to be the most mature developed Garmin product. I did see this neat Android application called OruxMaps
http://www.oruxmaps.com/index_en.html. It is free and showed the trails that I ride on by name! Impressive! Now the not so great - it doesn't navigate. It knows where you are and can cache the data you need when you are connected, but won't tell you how to get there. I guess it's okay if you know the area and just need your location. Personally I don't like to have one system for everything on something this critical. Also not useful for riding on the road. Rusty how did the Montana hold-up this year?
