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/obstacle databases are contained on a
datacard which is inserted in the right-most slot of the
500W Series units.
Database Versions
The version and area of coverage of each ter-
rain/obstacle database is shown on the Terrain Data-
base Versions Page, located in the AUX Page Group.
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.
