Which kind of map do you have ? Can you upload it? If you got from gps daemon separate tiles and you joined them ,you wont have a working map. You must use, as said, gpsdaemon from command: gpsdaemon /e and "Flash backup".
If you cant ,upload all the files and we'll see what it's possible to do with them.
PS. NT maps cant be edited. Unlockers just unlock maps in devices, so maps can be seen and used on them.
Garmin uses NT format to protect maps from editing and stealing details by other map makers.
OF / non-NT (old format / legacy format) maps can be edited by some map editor tools. The map data is normally the same in the NT & non-NT maps but some details might be removed in non-NT maps if it's close to 2 GiB in size. It's not possible to convert non NT maps to NT maps (quoted from a Ballebar's post)
