My etrex vista hcx with the right osm basemap installed sees all the paths, bike lanes, alleys, and general goat tracks everywhere. No elevation data available from the map, but thats ok. I get a hill graphic and that tells me I'm likely to be going up and the bariometric altimeter does the rest. I set it show elevation in one of the data fields. Phone gets used for nothing but taking pictures. The routing funcion will even find addresses and direct me there.
