    In my garmin I do not have a gmapsupp.img. There is a /garmin folder and a /map folder. The /map folder has gmapupdate.img, gmapupdate.gma, and gmapupdate.unl. Should I delete these 3 files and put in the gmapsupp.img?

      Backup gmapupdate.img, rename gmapsupp.img and replace, also you can have both.
