Just wondering if anyone else is experiencing the same problem. The Garmin xponder relies on GPS groundspeed to automatically go from "Alt" to "stby" mode after landing. This communication is not happening and therefore no auto switching to stby. The transponder uses different logic to go from stby to Alt on takeoff so that portion is working fine.
Also, a reminder that still no "Traffic Not Available" message on the IFD when outside of TIS-A coverage area

The GTX330 transitions from the Flight Timer, not the GPS groundspeed. The Flight timer can be controlled by several sources (one being GPS groundspeed) however, it depends on configuration and wiring. I would double check the configuration on the GTX, the specific config you are looking for is on 5.2.8.
