I am using Mapsource 6.16.3 patched. Using Maptool I can select my maps and on the left I can see the amount of megabites selected. When I select the "send maps" icon, Mapsource sees my USB stick and I click on send maps. Now I see a window saying "building mapset" and when this is completed I see for a brief moment "transferring Mapset". However the "transferring mapset" does not appear to happen. Following that I get a window saying "The data was successfully sent". When I check my usb stick there is a Garmin folder with only a small file inside named "gmapsupp.img". The file is size is only a few k's and much smaller than the data which should have been sent. When I try to send the same file to my Nuvi 760 it works just fine. Any help would be much appreciated.
