Gmaptool splitted .IMGs dont have search enabled:Gmaptool can create a Mapsource version starting from an .img map file, but these Gmaptool MS installations dont have search enabled because Gmaptool cant decode Mapsource address index in .img.(MDR subfile)
If you have original Garmin Mapsource installations made .IMGs instead, you can join them with Gmaptool ,like wrote in starting post and have search enabled because Mapsource imported correctly MDR files in the selected .IMGs.
Every JCV file is associated by its MAPID to its related .img, so it will work if the MAPID is the same in JCV and in .img.
