    G'day gelun, welcome to GPS Power.

    SP2720 has about 1.7GiB total usable internal memory i think. 672,100KB is way short of the 1.9GB you're trying to upload and even if you clear everything else off it's still not going to fit on there if i'm correct in recalling 1.7GiB and anyway maps are flashed to 'regions' which also have limited size which can't be exceeded regardless: Primary map to region 49 [hex 31] and supplementary map to region 10 [hex 0A], they seem to share flash memory space and i think it's a maximum of 1.1GiB if i recall correctly. Also an oem map can be flashed to region 50 [really tiny only 1MiB]. So, you'll need to reduce the size of the map to less than 1.1GiB even if you remove any other detail map.

    Thanks Neil for the information about Garmin StreetPilot 2720.
    Found that post #3 from “ultrasheer” in this thread explains it all.
    Creating .img-files with Mapsource and then proceeding with the WebUpdater-script in #3 shows that a file size of 1 815 168 kB fails while 1 796 064 kB works fine. After that both Mapsource and MapUpload(freware from wwwDOTmapwelDOTnet) reports Total Memory = 1 799 256 kB and 13-13.5 MB free space. MegaByte! Not much”
    Testing with a new small, 10.5 MB, .img.file with script as in #3 will erase everything in SP2720 and now Mapsource can move the large area into the 2720.
    Seems to me that WebUpdater.exe can unconditionally overwrite maps already in the 2720 while Mapsource/MapUpload can not.
