I just upgraded from Etrex vista to 64s. If I understood the salesman right this unit has only a basemap, highways, streets etc. with no topo maps on the unit and non can be loaded. If this is the case I need to return for next unit up. I do have the US topo from Garman on CD's that maybe could be loaded on a card and used if that would work. Also does gpsfiledepot have a manual for the 64s?
Thanks for any help.
