    Does the GTX-45r qualify as a Mode S xpndr w/ G3X + GNC355?

    I have a Garmin GTX-45r mounted behind my panel, controlled through the GDU-465 display in a G3X system. The ifr navigator is a GNC-355. Does the GTX-45r qualify as a mode-s in this install, and if so, what is the best way to make sure it is setup properly?
