Hello Ron,
As you know, your Aera 796 has 7 databases.
As shown on our
database pricing page, the North America Database Bundle that you purchased includes Garmin Navigation, Obstacle, SafeTaxi, Airport Directory, FliteCharts, IFR/VFR Charts, and Terrain (9AS) databases.
While the Navigation, FliteCharts, Terrain, SafeTaxi, and Obstacle databases provide merged coverage for both U.S. and Canada, you will need to choose between the U.S. or Canada for the Airport Directory, and IFR/VFR Chart databases because merged versions of those do not exist and the Aera 796 can only hold one each of all databases.
This is why you are being asked to answer that question on FlyGarmin.
Thanks,
Steve
