Looking for model suggestions for a GPS unit for a canadian.Alot of units only have USA maps or mapping sites that don't include coverage for me.trails.com only shows 6 trails in the areas I go to,and their are ALOT more than that!! Anyone know of sites that cover all of the rockies in AB/BC? What units are fellow canadians using? Never used one before,I'm old school..map,compass,familiar areas,and 2-way radios.Also, there's NO cell phone reception in these areas,and have heard some hikers have had their GPS units lose signal in some spots.
