The cycles and dates for both standby and active databases are displayed on the
“Aux – Databases” page on the MFD. Any active databases with expiration dates in
the past will be highlighted with amber text. When an expired active database has a
standby database that is ready to become effective, a cyan double-sided arrow will be
displayed between the database cycles. When this arrow is visible, it indicates that
the standby and active databases in that row will be switched on the next power cycle,
activating the current standby database. Databases can also be manually selected (or
deselected) by highlighting a list item and pressing the
ENT Key, provided a valid,
verified standby database is present.
In some cases it may be necessary to obtain an unlock code from Garmin in order
to make the database product functional. It may also be necessary to have the system
configured by a Garmin authorized service facility in order to use some database fea-
tures.
The navigation database contains the aeronautical data used by the system for the
flight management and flight planning functions. Included is detailed data for way-
points, procedures (arrivals, departures, approaches), and airways. The navigation da-
tabase is updated every 28 days.
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 up-
dated periodically and have no expiration date.
The obstacle database contains data for obstacles, such as towers, that pose a po-
tential 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.
The AOPA or AC-U-KWIK Airport Directory provides data on airports and he-
liports throughout the U.S. or worldwide, respectively. The AOPA Directory offers
detailed information for over 5,300 U. S. airports, along with the names and phone
numbers of thousands of FBOs. These databases are updated every 56 days. The
AC-U-KWIK Directory offers detailed information for more than 8,000 airports
with runways longer than 3,000 feet worldwide.
