Gps Configuration Page - Garmin G3X Installation Manual

17.3.13 GPS Configuration Page

The GPS Configuration Page allows selecting the GPS source for each GDU. Each installed GDU can
select either the GPS antenna directly connected to that GDU, or 'No GPS Antenna Connected'. If 'No
GPS Antenna Connected' is selected, that GDU will use GPS data from the GDU that is connected to a
GPS Antenna. Only one GDU need be connected to a GPS Antenna, that GDU will "share" the GPS info
will all other GDUs.
NOTE
Failure of a single GDU or GPS antenna (in a multi-display/multi-antenna installation)
would cause the system to use GPS information from the remaining functional GDU. If no
GPS data is available from any operating GDU, the remaining GDUs will use GPS
position data from an external GPS navigator (GNS 400/500, GNS 480, or GTN 600/700

If an external GPS navigator is configured, the GPS config page displays "Select External GPS At
Powerup". This setting controls whether the user's choice to use the internal GPS nav source will be
retained between power cycles (disabled), or if the system should always return to using the configured
external GPS nav source at powerup (enabled).
