I use eTrex Vista, which is a cheaper model than 60csx and I use OSM data + separate contours without problems. The order of loading maps is important (when you look at the list of maps on your GPS unit, contours maps should be at the end of the list). And I think certain maps have some sort of "transparency" setting turned on, and some do not, but I'm not sure. I use contours which were generated with DEM2TOPO tool (I didn't do this myself). > Can anyone help with this?
