SECTION 11
TERRAIN
General Database Information
The Garmin TERRAIN system uses terrain and obstacle
information supplied by government sources. The data
undergoes verification by Garmin to confirm accuracy of
the content. However, the information displayed should
never be understood to be all-inclusive. Pilots must
familiarize themselves with the appropriate sectional
charts for safe flight.
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 terrain and obstacle databases are contained on
a datacard which is inserted in the right-hand slot of the
GNS 430 unit, see Appendix A for more information.
Database Versions
The version and area of coverage of each terrain and
obstacle database is shown on the Terrain Database
Versions Page, located in the AUX Page Group
(Figure 11-3). Databases are checked for integrity at
power-up. If a database is found to be missing and/or
deficient, the TERRAIN system fails the self-test and issues
a failure message (Section 11.3).

Database Updates
Terrain and obstacle databases are updated periodically
with the latest terrain and obstacle data. Visit the Garmin
website to check for newer versions of terrain and obstacle
databases (compare database cycle numbers to determine
if a newer version is available). Updated terrain data cards
may be obtained by calling Garmin at one of the numbers
listed in the front of this document.
To update the terrain or obstacle database:
1) Acquire a new terrain data card from Garmin,
or download the terrain and obstacle database
from the Garmin website (www.garmin.com).
2) Turn off the power to the GNS 430.
3) Remove the old terrain data card from and
insert the new card into the right-most slot of
the GNS 430.
4) Turn on the GNS 430 and verify that the
TERRAIN system passes the self-test.
