GARMIN GTX 325 TSO'd Panel-mounted Mode A/C Transponder SKU: GRMN-XPDR-GTX325

GARMIN® GTX™ transponder product line includes Mode A/C and Mode S TSO'd panel mounted transponders offered in a‭ ‬wide variety of configurations to choose‭ ‬from‭, ‬depending on desired functions‭.‬ Different models are listed under separate product presentations. 

GARMIN® GTX™ 325  is a Mode A/C panel-mounted full-featured, TSO'd certified transponder offering a simple, affordable replacement for standard Mode C transponders. It features aural alerts, total air temperature (TAT), pressure altitude readout, altitude monitor function, density altitude readout, built-in timers and automatic ALT/GND mode.  ‬It replaces the popular GTX™ 327 ‬and is essentially the same unit‮—‬but carries the GTX™ 335/345‭ ‬display and button layout‭. ‬It would be a meaningful ‬choice for the replacement of an older Mode C ADS-B‭ ‬Out transponder.

GARMIN® GTX™ 325 Mode A/C panel-mounted full-featured, TSO certified transponder offers a simple, affordable replacement for standard Mode C transponder units in aircraft that don’t fly in ADS-B mandated airspace — or that will be equipped with a separate UAT ADS-B transceiver solution like the GDL 82. Its solid-state design works to maximize service life and assure dependable ATC traffic surveillance.

Featuring an easy-to-read LCD display designed for optimal viewing in all lighting conditions, GTX™ 325 offers a number of useful timing and display functions. Timers include trip time, flight time, count-up and count-down, while display functions include readouts for density and pressure altitude as well as static (outside) air temperature. In addition, the altitude monitor function displays the current deviation from the chosen altitude, as well as provides a “leaving altitude” alert when the deviation exceeds the preset limit. Dedicated push buttons numbered 0 through 9 make for quick and easy squawk code entry, while a dedicated VFR button pulls up the VFR code with a single keystroke. Compatibility with the GTN 750 and GTN 650 series of integrated GPS/Nav/Comm systems also enables transponder code selection and control from your navigator’s touchscreen display.

The GTX™ 325 transponder can also be paired with an optional Garmin altitude encoder to satisfy Mode C data transmission requirements for IFR. The external Garmin altitude encoder mounts separately on the install rack. So, if the transponder ever requires removal, there’s no need for the static line to be disconnected. In turn, that eliminates the need for a follow-on leak check — and thus helps minimize ongoing service costs.

No matter how the aircraft is currently equipped, GARMIN® GTX™ 325 offers a simple, all-bases-covered transponder upgrade solution. The standard size and form factor of the 1.65” high unit assures a straightforward replacement for most existing stack-mount transponders — preventing extra avionics rework and installation downtime.
