Garmin GTX345 ADS-B (In/Out) Transponder with Built In GPS

The GTX™ 335 and GTX 345 incorporate the popular 1.65-inch (4.2 centimeters) tall panel-mount transponder form factor and boast a bright, sunlight-readable digital display, including a pressure altitude readout and flight timers,
along with dedicated buttons for numeric squawk code entry. An option for an integrated WAAS/GPS position source provides aircraft owners and operators with an all-in-one solution that meets worldwide ADS-B “Out” requirements.
The GTX 345 includes a dual-link ADS-B receiver that delivers pilots a complete ADS-B-provided traffic picture. When paired with compatible displays, the GTX 345 adds subscription-free Flight Information Service-Broadcast (Not in NZ)
and ADS-B traffic, incorporating exclusive features such as TargetTrend™ and TerminalTraffic™.
Remote mount options are also available for control and display within G1000 and GTN 650/750-equipped aircraft.
When paired with an active traffic system, the GTX 345 combines ADS-B traffic targets and active traffic targets to display a comprehensive traffic picture.
Beyond the display, the GTX 345 may be integrated into the aircraft’s audio panel to provide ATC-like audible alerts, such as “Traffic: 10 o’clock, same altitude, 2 miles,” to help pilots keep their eyes outside the cockpit when looking for traffic.
Additionally, an optional altitude encoder is available and conveniently mounts to the transponder backplate for easy installation and service, precluding the need for a static leak check after removal of the transponder for maintenance. 
Select G1000 equipped aircraft, either with or without WAAS, now have an elegant and simple path for ADS-B.
A remote-mounted version of the GTX 335 or GTX 345 takes the place of the aircraft’s transponder and interfaces with either the aircraft’s existing WAAS position source or the optional integrated WAAS position source to meet worldwide ADS-B “Out” requirements.
The G1000 display interfaces to the transponder to provide squawk code entry and control in the same manner as before.
The dual-link GTX 345 provides the capability to display various ADS-B “In” benefits (G1000 software version dependent) on the Primary Flight Display (PFD) and Multifunction Display (MFD).
Pilots may view subscription-free weather¹, including NEXRAD, METARs and TAFs, on the MFD as well as ADS-B traffic targets on the MFD and PFD for aircraft equipped with Synthetic Vision Technology (SVT™).
Additional ADS-B “In” benefits can be wirelessly streamed to a Garmin GPS portable such as the aera® 795/796 and the most popular apps in the industry, including Garmin Pilot and ForeFlight Mobile. Additionally, when integrated with an active traffic
system, ADS-B traffic and active traffic targets are merged by the GTX™ 345, giving pilots an optimal traffic picture.
In addition to G1000, the GTX 345 integrates with thousands of installed displays to provide the benefits of ADS-B “In,” further extending existing avionics investments.
This initially includes the popular GTN 650/750 touchscreen series and GNS™ 430W/530W GPS/NAV/COMM navigators, GMX 200/MX 20, aera 795/796, Garmin Pilot, ForeFlight Mobile and compatible third-party displays.
Additionally, customers may pair the GNS 480 with the GTX 335/345 and use the integrated WAAS position source to achieve ADS-B “Out.”
Support for G500/G600 is expected in Q2 2016, while G3X Touch support is expected in Q3 2016.
Pairing the transponder with a display overlays TIS-B traffic and subscription-free FIS-B weather¹ on top of colorful, moving maps with reference to airspace, terrain, flight plan information and more, so it’s easier to identify traffic and weather of concern.
FIS-B weather products include NEXRAD, METARs, TAFs, PIREPs, winds and temperatures aloft, NOTAMs, AIRMETs and SIGMETs.
Exclusive traffic features such as TargetTrend and TerminalTraffic further enhance the traffic picture. TIS-B traffic and FIS-B weather display capabilities vary by product.
Regardless of the existing avionics configuration, the GTX 345 displays an incredible amount of valuable flight information on compatible portable devices.
With the GTX 345, customers can wirelessly receive ADS-B traffic and weather as well as precise GPS position data for use within mobile applications.
Wireless compatibility initially includes the popular aera 795/796 portable aviation GPS and mobile applications, including Garmin Pilot and ForeFlight Mobile.
SVT is enhanced by the AHRS within the transponder, displaying GPS-derived airspeed, altitude and vertical speed overlaid on a rich 3-D topographic landscape.
Traffic is also transformed within Garmin Pilot, leveraging the Garmin exclusive TargetTrend and TerminalTraffic technologies.
Note:  Includes Garmin GA35 WAAS GPS Antenna.
