Looked again at this. Some of the file names for the downloads SEEM to have the Skyview Firmware version as a part of the name. This includes the main firmware, the aviation and the obstacle data. All three of these have had "2.0." in the name for Skyview Version 2.0. The latest aviation data has "2.6" in the name not "2.0". Is this accidentally a database for a beta version of Skyview?
