Have you tried if there is a difference whether the gmapsupp got created 
by mkgmap, sendmap or Basecamp/Mapsource??
Maybe mkgmap makes some mistakes when creating the gmapsupp, and on big 
files it doesn't work. Note however that in any case a map like whole UK 
will take quite some time to import to Basecamp (and lots of RAM).
