to select the whole map whithout missing any part ,keep it little and select it all, like shown here
create the gmapsupp.img , you'll find it in C:\Garmin , rename exactly like the old one, connect your device and replace it --it's better you backup the old one on your pc before replacing it- The GMAPPPROM.UNL file is the old map GMAPPPROM.UNL file,backup it with the old map too and you wont need it with the new one coz it's unlocked-
