I purchased a gpsmap 76s the other day, and wonder if your able to upload Delorme map softwared to it. I like the looks of the Delorme Topo USA 4.0. I called Delorme sales tonight and they told me if I loaded their atlas metro software I would be able to load their Topo. About everything else I read says I can only use Garmin's mapsource. Anyone know for sure??
