The offline maps are now on the p4a+ and p4p+ controllers with the new software 4.2.16 for dji go 4 app. You can download the maps at home and have them out in the field the same as the crystalsky. You can rename the area to download but it is a little awkward after each letter press the backspace key to rename your area.
