Garmin has introduced the GTX 345 and GTX 335 all-in-one ADS-B transponders, which include Extended Squitter (ES) ADS-B Out with options for built-in WAAS, as well as dual-link ADS-B In.
The GTX 345/335 integrate on a wide variety of current and legacy Garmin displays, including select G1000 Integrated Flight Decks, according to company officials.

The GTX 345 unlocks more capabilities for pilots by displaying ADS-B traffic, subscription-free weather, GPS position data and back-up attitude information on the Garmin Pilot and ForeFlight Mobile apps via Bluetooth and Connext wireless technology.
The GTX 345/335 come in a size that makes it easy to replace other transponders in the industry, like the Garmin GTX 327.
Remote options are also available for compatibility with the GTN 650/750 series and G1000-equipped aircraft.
Prices start at $2,995.

The GTX 345 and GTX 335 incorporate the 1.65-inch-tall panel-mount transponder and feature a sunlight readable digital display including pressure altitude readout, dedicated buttons for numeric squawk code entry and a built-in timer.
In addition to G1000, the GTX 345 integrates with thousands of installed displays to provide the benefits of ADS-B In, including GTN 650/750 touchscreen navigators and GNS 430W/530W navigators, aera 796/795, Garmin Pilot, ForeFlight Mobile, and other third-party avionics.
Compatibility for the G3X Touch glass flight display is expected in the third quarter of 2016. Support for G500/G600 is expected in the second quarter.
Additionally, customers may pair the GNS 480 and the GMX 200/MX 20 multi-function displays with the GTX 345/335 and use the integrated WAAS position source to achieve ADS-B Out.
The GTX 345 and GTX 335 transponders have received the FAA’s Technical Standard Order (TSO) authorization and is expected to receive supplemental type certification (STC) later this month for installation in hundreds of aircraft makes and models. European Aviation Safety Agency (EASA) validation is expected later this year.
The GTX 345 transponder provides ADS-B In/Out capabilities and is available with and without WAAS for a list price of $5,795 and $4,995 respectively. The GTX 335 ADS-B Out transponder is available with WAAS for $3,795 and without WAAS for $2,995.
Why can we just upgrade our 430/530 units like we were originally when we purchased them,
lots of these units out there serving our planes well but soon to be obsolete thanks to Garmin.
All in one makes it so convenient, only one stop needed to empty my wallet.
So, the teaser price point of $3k does not come close to complying with the mandatory beltway-Versailles edict. The built in WAAS costs twice as much? Really? This ADS-B thing is a complete, anti-GA scam!
