I've already used Fast IMG unlocker to open the map, and it works. But I want to lock/secure the map.
I've copied the original map (GMAPSUPP.img) to a memorycard, and created a GMAPSUPP.UNL with a code generated from Jetmouse. But when I boot up the GPS, I get this error: "The map can not be verified"

Maybe Jetmouse can't generate codes for this new map? MapID is 4548. It's a Topo Premium map for Norway
