Quoting Felix Hartmann <extremecarver at googlemail.com>:

I did not notice this problem, but perhaps you missed one step? After  
you import the img file into gpsmapedit you must select

file->Select->By Type

from the menu and select the background (0x004b-polygon-other-Map  
coverage area) and delete it.
