SECTION 10 TERRAIN Database Updates Terrain/obstacle databases are updated periodically 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). Updated terrain data cards may be obtained by calling Garmin at one of the numbers listed in the front of this document. Updating terrain/obstacle databases: 1) Acquire a new terrain data card from Garmin. 2) Turn off the power to the GNC 420. 3) Remove the old terrain data card from and insert the new card into the right-most slot of the GNC 420. 4) Turn on the GNC 420 and verify that the TERRAIN system passes self-test.
