GTX Pressure Altitude Input

In most installations, the GTX 35R/45R receives pressure altitude data from the G3X system. An optional
GAE sensor module is available for installations requiring pressure altitude data that meets the
requirements of TSO-C88b. When a GAE is installed and configured, the GTX 45R/45R will prioritize
pressure altitude from by the GAE over altitude data from the G3X system. Configuration and calibration
of the GAE requires the use of the dealer-only software tool described in Section 6.4.

ADS-B In Considerations (GTX 45R Only)

The GTX 45R provides ADS-B In data regardless of the state of the transponder. HSDB ADS-B In
displays cannot connect to more than one ADS-B In source.
NOTE
Do not install with a GDL 88.

Bluetooth Considerations (GTX 45R Only)

For optimal connectivity with a GTX 45, the Bluetooth antenna must point towards the passenger area of
the aircraft. This is identifiable by the Garmin logo sticker. Bluetooth performance may be limited by
aircraft obstructions.
