I'm about ready to buy my 1st topo GPS unit. I have a Garmin NUVI 350 for our cars and love it so I'm sticking with that brand.

Just talked to a Garmin "Outdoor GPS" guy & he said the new Garmin Colorado 400 T, due in stores & online in a month or two, is their best topo GPS. The 400T (T for topo) is PRE LOADED with N. American topos as part of the price. Also this unit will take coastal navigation charts - good for my sea kayaking trips.

The 400T is waterproof to a few feet of water, takes a micro SD card (up to 2 Gb) and can use aftermarket software to download trails.

1. Is <trails.com> the best source of these downloadable trail maps?

2. Does Nat'l. Geo.Trails have the software for downloading their trail maps? I like the accuracy of their plasticized paper trail maps.

3. What experience has anyone had with downloading trails to their personal download-capable GPS units?
