GARMIN DATABASES
The following databases are stored on Supplemental Data Cards provided by Garmin:
• Expanded basemap • SafeTaxi
• Terrain • Airport Directory
• Airport Terrain • Obstacle
After subscribing to the desired database product, these database products will be downloaded and ultimately
stored on two Supplemental Data Cards. Each Supplemental Data Card resides in the bottom card of each
display as shown in Figure B-7. These cards must not be removed except to update the databases stored on
each card.

Since these databases are not stored internally in the displays, a Supplemental Data Card containing identical
database versions must be kept in each display unit.
The basemap database contains data for the topography and land features, such as rivers, lakes, and towns.
It is updated only periodically, with no set schedule. There is no expiration date.
The terrain database contains the terrain mapping data. These databases are updated periodically and have
no expiration date.
The obstacle database contains data for obstacles, such as towers, that pose a potential hazard to aircraft.
Obstacles 200 feet and higher are included in the obstacle database. It is very important to note that not all
obstacles are necessarily charted and therefore may not be contained in the obstacle database. This database is
updated on a 56-day cycle.
NOTE: The data contained in the terrain and obstacle databases comes from government agencies. Garmin
accurately processes and cross-validates the data, but cannot guarantee the accuracy and completeness of
the data.
