from Mapwel help
Mapwel is available in free demo version for evaluation purposes. Demo version truncates map uploaded into GPS (unless it is Mapwel_Island.MPW test file) and it has also the multiple files upload option disabled.
Sample Map To test the map into GPS upload and to see how the finished map looks in the Mapwel, use the Mapwel_Island.MPW file in the MAPWEL/FILES folder. You can upload this map into GPS without truncation even if you have unregistered version of software. Note: map elements like areas, lines and symbols appear gradually as you zoom-in the map in GPS. Use the Setup/Map/Detail menu in GPS to set detail level.
