At first I could get the device to sync after upgrading to V2.0 on the pc . Another day, another a try, and the sync worked, except it overwrote the map already present. Then when booting SD mobile there is a message saying 'no maps installed' or words to that effect. Fortunately, I had a back up of the SD files from previous version, so I copy across the file that seems to be the map data file. Re-boot & the map is there, except it no longer shows any terrain. The airfields, airspace, dots for spot heights (no figures) are there, just no ground at any zoom level!



Have I missed a file somewhere or what?
