I am installing a Trig TT21 transponder and using a Garmin 420 W for the ADSB feed. Setup in the Trig is asking for the Navigational Accuracy Category for velocity (NACv) for the Garmin. Says it will be in the GPS installation manual but I can't find it. Has anybody come across it? It will be the same for both the 420 and 430 W.
