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 features.
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.
The data contained in the terrain and obstacle databases comes from government agencies. Garmin
NOTE:
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 heliports 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.
The SafeTaxi database contains detailed airport diagrams for selected airports. These diagrams aid in following
ground control instructions by accurately displaying the aircraft position on the map in relation to taxiways,
ramps, runways, terminals, and services. This database is updated on a 56-day cycle.
The FliteCharts database contains procedure charts for the United States only. This database is updated on a
28-day cycle. If not updated within 180 days of the expiration date, FliteCharts will no longer function.
The ChartView database is updated on a 14-day cycle. If the ChartView database is not updated within 70
days of the expiration date, ChartView will no longer function. The ChartView database must be purchased
directly from Jeppesen, but can be updated at www.jeppesen.com or www.flygarmin.com.
