If there is no MAP ID ( as they are free, like caty said), you dont need the "GMAPSUP.UNL" or anything from the keygen except your "SW.UNL" code.
Thats what I ended up doing and my unit recognized the maps. No need for .UNL for this. Just named it GMAPPSUP1 or some thing like that and placed it in Garmin folder on E and it worked fine.
