This version of the Garmin GTX-335 offers ADS-B Out, but it does not contain an internal WAAS GPS Receiver.  This GTX-335 must be paired with a WAAS GPS Navigator to obtain a position fix for ADS-B.  On the plus side, you are not paying for another WAAS GPS, but using the one already installed in your aircraft.  This GTX-335 will modernize your panel with an ADS-B Out solution, delivering capability, performance, simplicity and compliance.

Reliable Mode S Transponder with 1090ES ADS-B Out
The GTX-335 transmits using 1090 MHz Extended Squitter (1090ES) technology, which is permitted at all altitudes and required for flights above FL180 or in Class A airspace. It broadcasts your aircraft’s flight ID, position, velocity, altitude trend, and heading.  This gives ATC and nearby traffic a clearer picture of your location and intentions. This level of visibility increases situational awareness and contributes to a safer airspace for everyone.

Intuitive Display and Controls
Pilots will appreciate the clear, high-contrast display and straightforward operation. The large, bright digital display is easy to read in all lighting conditions. A dedicated VFR button instantly sets the squawk code to 1200, while the numeric keypad makes it quick and easy to enter other Transponder codes. Altitude deviation alerts help you stay on top of assigned altitudes, and timers—count up, count down, flight, and trip—add useful utility to your cockpit workflow.

Useful Data at a Glance
With the right inputs, the GTX-335 can display static outside air temperature and density altitude, offering additional environmental and safety awareness. It also shows encoder-supplied pressure altitude, keeping critical flight data right in front of you.

Compact and Versatile
At just 1.65 inches tall, the GTX-335’s slimline design saves valuable panel space. While it is not a plug-and-play replacement for your Transponder, it may fit in the panel space vacated by your radio.  And the GTX-335 is certainly more capable and reliable than your old Mode C Transponder.

Garmin’s GTX-335 (without WAAS GPS) is ideal for pilots seeking ADS-B Out compliance, while using your installed WAAS GPS Navigator as a position source. With its reliable Mode S performance and pilot-friendly design, it’s a smart upgrade for modern flying.
