Access chart panels offline
When you're not in cell range, and no wifi signal, the app will not refresh the downloaded charts as you move off the endge of the downloaded map. If the app could draw from a set of charts on an SD card, you could truly use it as a moving map/ chartplotter. Would be good to have course, speed, etc functions as well.
Loading charts via an SD card or removable media is something that we could implement (via Android, not iOS) once we have the right security technology in place – which is non-trivial. What we are focusing on right now is increasing the download region size per download so its a less onerous process. We’ll keep optimizing that process and see if that doesn’t resolve the problem at large.
