General Information
GNS 480 (CNX80) Installation Manual 560-0982-01 Rev L 1-17
1.5 Database Updates
The GNS 480 utilizes a database stored on a CompactFlash Memory datacard for easy updating and
replacement. The database is updated by simply inserting an updated database card into the slot in the
front panel in the GNS 480.
The GNS 480 comes with a CompactFlash memory card reader/writer (R/W). The R/W is intended for
updating the included database card using a PC. Refer to the installation manual included with the R/W for
instructions on how to install and operate the CompactFlash R/W.
The database on the GNS 480 database card is generated from current Jeppesen-Sanderson data and
converted to a format that is used by the GNS 480. The data conversion process is performed using
software that is developed and maintained under Garmin AT configuration management according to
RTCA/DO-200A, Standards for Processing Aeronautical Data.
GNS 480 users update their database card by purchasing database subscription updates from Jeppesen-
Sanderson. The database card is programmed using the supplied CompactFlash memory card R/W and
Jeppesen-provided software. Contact Jeppesen at 800-621-5377 or www.jeppesen.com for more
information and instructions.
Contact Garmin AT, Inc. for information on databases available for the GNS 480.
CAUTION
Do not insert or remove the data card within 10 seconds after the GNS 480 is turned
on.
