I have a Skyview system with AP, GPS, ARINC, 261 Transponder. I recently downloaded 5.0, aviation, and obstruction databases seperately. A red warning appeared on the map page which read something like "aviation data out of date". I didn't think too much about it, thinking maybe the warning was because I didn't update the map database. I then downloaded 5.1 as a package with the included databases. The warning still appears. What should I do. Thanks.
