1.8 GTN Databases
The GTN utilizes various databases. With the exception of the Navigation, Basemap, SafeTaxi, and
Obstacle databases which reside internal to the GTN, all databases are stored in a single SD memory card
that is inserted into the vertical slot on the left side of the GTN. The following describes each database
and how the databases are updated. See Table 1-11 for a summary of the database location and update
rate.
The GTN Database card, Garmin Part Number 010-00900-00, includes the following databases:
Basemap, Obstacle, SafeTaxi, and Navigation.
CAUTION
The databases on the Supplemental Data Card are locked to specific GTN installations.
The first time the Supplemental Data Card is inserted into a GTN, it associates
exclusively with that particular GTN and will not work in other installations.

1.8.1 Basemap Database
The basemap provides ground-based references such as major roads and bodies of water. The database is
stored in the GTN internal memory. The basemap does not have a scheduled update cycle and as such
does not have an expiration date. The basemap database is updated infrequently. Should this database
need to be updated in the future, Garmin will provide details on how to load the updated data into the
GTN.
