Ok. Just to see if I understood - I now have base maps and only one map - gmasupp.img, but no .unl file because I have unlocked maps in Mapsource. So,do I have to rename this mape to gmapprom. and leave it without .unl file, and later add new gmasupp files with .unl, or I can add Auto drive Hellas as a gmapprom image with unl? Tnx!
