Notes:
[1] The Generic MAPMX GPS format may be used for Garmin GNS 4XXW/5XXW and
GNS 480 interfaces if there are not enough data ports. This interface only requires
RS-232 and provides the GI 275 with GPS position for moving map and AHRS aiding.
TAWS Installations
If a single TAWS-equipped GTN 6XX/7XX, GTN Xi, or GNS 500W unit is installed, it must be
configured as GPS 1. Only TAWS annunciations from GPS 1 are displayed on the GI 275.
GNS 400W/500W Series and GNS 480 Installations
In dual GNS installations, the ARINC 429 OUT port selection is configured the same for both GPS 1 and
GPS 2. The GPS 2 ARINC 429 OUT port is automatically set based on the port selection made on GPS 1,
or vice versa. Changing the port selection on one will automatically change it on the other. Set the
remaining ports for both per the associated aircraft wiring diagram.
