I downloaded the Topo Pro Premium Trondheim from this site, that is already unlocked. It workes perfect. So I'm clearly having problems with unlocking the map I'v got from a original SD. It's Topo Pro Premium Steinkjśr.
I'v tried to use the gimgunlock+MapSigPatch. I draged the GMAPSUPP.img file on the gimgunlock file. I can see in the cmd window, that it skippes lot of files. Is this normal?
