Designed exclusively for Europe, GTX 328 satisfies the European requirement for a Mode S solution that meets the reduced certification requirements for the VFR Mode S mandate. GTX 328 is intended to serve VFR/Class 2 aircraft where there is adequate size and power consumption support for a GTX 328 unit and is a straightforward retrofit. GTX 328 offers the same great value, reliability and innovation that pilots and aircraft owners have come to know from Garmin — at an affordable price.

Enjoy Innovative Design

Similar to GTX 330, GTX 328 includes features such as displaying outside air temperature, altitude monitoring, count up and count down timers (using a built-in digitized voice annunciator to alert the pilot when preset altitude limits have been exceeded or timer expiration), density altitude functions and front-panel input for flight ID.

Since the GTX-330 Mode S Transponder provides TIS (Traffic Information Services), EHS (Enhanced Mode S) functionality and transmits power that exceeds the requirement for VFR aircraft in Europe, the European GTX 328 does not offer TIS, EHS or ADS-B functionality.

GTX 328: Meets European flight regulations without breaking the bank.
