You can put maps of certain areas in ahead of time. I'm not at home right now and don't have access to
SC so I can go through the process, but I remember I found it pretty easily just by going through the controller. You can only put in a limited number of maps, and would need to remove some that are not needed to add new ones. The other day I flew in the same area as a year ago and the maps came up as needed, so apparently they're still in there. If your cell phone can be setup as a mobile hotspot, that works great as well. Just setup the
SC to log on to the hotspot and it will log on whenever you enable the hotspot. The area I put the maps in ahead of time has no cell service in the area. Once put in, the maps come up whenever you fly in that area.
