6 CONNEXT  BLUETOOTH

The GTX 345 Connext interface allows communication with apps (i.e., Garmin Pilot 
and ForeFlight Mobile), while running on a PED. Connext works via the Bluetooth 
data link to provide up-to-date, wireless information throughout the cockpit. Refer to 
section 3.4 for Bluetooth pairing instructions. Up to two Bluetooth connections are 
supported by the GTX 345. Table 6-1 lists the GTX 345 Connext features.

Table 6-1  GTX 345 Connext Features

GTX 345 CONNEXT FEATURES

GPS Position and Velocity 

• 

GPS position and velocity information used by the GTX 345's certified ADS-B 
functionality is made available to PEDs

.

ADS-B In Traffic 

•  ADS-B In traffic data that is provided to certified traffic displays is made available to 

PEDs. This traffic is also combined with TCAD/TAS/TCAS traffic when the systems are 
integrated during installation.

FIS-B Weather and Flight Information

•  FIS-B weather and flight information that is provided to certified displays is made 

available to PEDs.

Pressure Altitude

 

•  Uncorrected barometric pressure altitude used by the GTX 345's certified transponder 

and ADS-B functionality is made available to PEDs.

Attitude and Heading Reference System (AHRS)

 

•  When the GTX 345 is installed as part of an integrated flight deck (e.g., G500/G600, 

G1000), AHRS data from an AHRS source is made available to PEDs. 

•  When the GTX 345 is installed as a stand-alone device, a built-in sensor provides 

AHRS data to PEDs via Connext. Attitude data is not output to other installed 
avionics.

•  The internal AHRS sensor is for use in fixed-wing aircraft only and is disabled in 

helicopter installations. All internal AHRS functions are automatic and no pilot action 
is required.
