Can't upgrade to V16
Having a great deal of problems with this upgrade to my 5400, S/N 1741. I loaded the upgrade file along with the HRTERRAIN file and new maps onto a USB stick and followed the installation procedure. It loaded but upon restart I found that my engine data and a lot of other data was missing from the screen, and the screen was not swipeable in any direction. I tried to load the HRTERRAIN data but it would not load and the screen has a flashing HI RES TERRAIN NOT FOUND flag. See the attached photo. Tried to redo the update procedure but it wouldn't load again. So I'm out of ideas and I have a flight on Monday. Can you offer any suggestions? Is there any way I can go back to V15?
