Maybe I'm doing something wrong, but I just upgraded from an Oregon 600t to the 66i and found virtually no trails showing on a backpacking trip through the Wenaha-Tucannon Wilderness in eastern WA state. I remembered using my Oregon in that area and always found trails showing. After the trip, I double-checked this as well as many of the trails in eastern WA and north ID and found many very well-traveled trails that are all on the Oregon are nowhere to be found on the 66i! I understand that the Oregon has the Topo US map vs Topo Active on the 66i, but I would think that buying the top of the line handheld, Topo Active would be at least have equally as many trails represented. Has anyone found this to be the case or is there some feature that I'm missing to show these trails? If it is the case (which is pretty reprehensible), is there a way to add the Topo US maps?
