Your device can read from Map folder, any map file, with any file name with .img extension.

Having overlapping maps selected simultaneously can lead to conflicts. When selecting (checking) a map, some automatically deselect (uncheck) overlapping maps that are found. Consider those maps "Murphy-proof".
