Notes:
[1] Disabling the Transmit Selected Course to the GTN configuration setting will prevent the course
selected on the GI 275 from crossfilling to the GTN 6XX/7XX or GTN Xi. Disable this setting when
the GI 275 has Course Selection enabled but is not the primary HSI/CDI interfaced to the GTN.
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.

VFR GPS

The VFR GPS antenna must be installed to enable the VFR GPS per this STC. Set VFR GPS to Internal if
the antenna is directly connected to the unit. Otherwise, set to Other GI 275.
The built-in VFR GPS is only approved for VFR navigation.
