Database Updates
Terrain/obstacle databases are updated periodi-
cally with the latest terrain and obstacle data. Visit the
Garmin website to check for newer versions of terrain/
obstacle databases. Compare database cycle numbers
to determine if a newer version is available.
The database update process includes either
reprogramming or replacing the database card and
inserting the updated card in the right card slot on the
unit front panel. The terrain/obstacle database may
be downloaded via the internet and the card repro-
grammed using a USB programmer available from
Garmin. Contact Garmin at 800-800-1020 or at
www.garmin.com for more information.
To update your terrain/obstacle databases:
1. Acquire a new terrain data card from
Garmin.
2. Turn off the power to the 500W Series unit.
3. Remove the old terrain data card and insert the
new card into the right-most slot of the 500W
Series unit.
4. Turn on the 500W Series unit and verify that
the TAWS system passes self-test.
