You cannot install a *.img with Mapinstall to an other unit I guess. Mapinstall will read gmap or old MS maps. Basecamp can read them, thats all. Just use explorer (or other Program) to copy the map to Your device.
In Your case there are probably no other (unlocked) maps on the PC, with that message from Mapinstall ?
Did You want some maptiles for only Belux ? , the PC version is on this forum which You can use with Mapinstall.
