Jeppesen Database Information

The GPSMAP 495 includes an internal Jeppesen

®

 database that 

provides location and facility information for thousands of airports, 

VORs, NDBs, and more. The following information is provided 

from the internal Jeppesen database:
Airport—* identifier, facility name, city/state/country, latitude/

longitude, field elevation, available fuel types, runway designations 

and layout, runway surface, runway length, runway width, runway 

lighting, communication frequencies, and published approaches.
Weather—frequencies associated with an airport (ASOS, ATIS, and 

AWOS).
VORs—* identifier, facility name, city/state/country, location 

(latitude/longitude), frequency, service volume (high, low, terminal), 

and type (such as VOR-DME, TACAN, and VORTAC). 
NDBs—* identifier, facility name, city/state/country, location 

(latitude/longitude), and frequency.
Intersections—identifier, nearest VOR, radial and distance from 

nearest VOR, location (latitude/longitude), and region/country.
ARTCC—Air Route Traffic Control Centers.
Airspace—boundaries (Class B, Class C, Control Zones, SUAs, and 

MOAs), controlling agency, and vertical boundaries.

FSS—Flight Service Stations.
* Symbology used for NDBs, VORs, and airports is consistent with 

those used on a sectional chart.

Updates to the Jeppesen database are available every 28 days online 

(

). The update programs 

are designed to operate on Windows

®

-compatible PCs and requires 

the included USB Interface Cable to be connected to the unit and an 

available USB port on your computer.

  NOTE: After you perform an update to your Jeppesen database, 

verify that all of the flight plans (routes) in your unit are current. 

If there is an obsolete Jeppesen aviation point in a saved route, 

the route is locked and unusable. You need to create a new route 

with current Jeppesen database points.

An optional FlightBook software package is available to assist with 

your flight record keeping. Visit the Garmin Web site at
