APPENDIX B
TERRAIN AND OBSTACLE DATABASES
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.
NOTE: Obstacles 200’ 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.
G1000 topography, terrain, and obstacle data is stored on a Supplemental Data Card provided by Garmin.
The obstacle database update cycle is every 56 days. The terrain database is updated less often, and on an
irregular basis. Since these databases are not stored internally in the MFD or PFD, Supplemental Data Cards
containing identical database versions must be kept in both displays to retain terrain and obstacle data. A
Supplemental Data Card should be inserted into the bottom card slot of the PFD and MFD.
NOTE: If the Supplemental Data Card is removed from the display, the TOPO and TERRAIN softkeys are
not functional and are grayed out on the MFD Map Page.
The obstacle and terrain database updates can be obtained by following the instructions detailing in the
‘Aviation Databases’ section of the Garmin website (www.garmin.com). Once the updated files have been
downloaded from the website, a PC equipped with an appropriate SD card reader is used to unpack and
program the new databases onto the existing Supplemental Data Cards. Equipment required to perform the
update is as follows:
• Windows-compatible PC computer (Windows 2000 or XP recommended).
• SanDisk SD Card Reader, P/Ns SDDR-93 or SDDR-99 or equivalent card reader.
• Updated database obtained from the Garmin website.
• Existing 010-00330-41 Supplemental Database SD Cards from both PFD and MFD.
