To fully explain, 30/40/50 is the same as most modern nuvis as to file structure. No need to only use the legacy naming (gmapprom.img etc) for detail maps in .system folder. Simply create a new folder named "Map" in the root of unit or sd (x:/Map) and then you can copy map images into there with any name that's convenient eg USA.img; EU.img etc.
