Are you sure? 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).
