I have the TRUTRAK Digiflight II VSGV autopilot installed in my RV-7A. It is at software/firmware V2.34. I have not been able to get "GPSS" to display on the AP display indicating that is in GPS steering mode. Rather the AP displays "EXT LS" when switched from heading mode which I presume means it is receiving ARINC Lateral Steering commands from the GTN-650. The AP seems to be working as if in GPSS mode (Roll Steering) as it anticipates turns before overflying waypoints. I recently read in a GRT forum that TRUTRAC Systems at some point replaced "GPSS" with "EXT LS" in some versions of the Digiflight II VSGV autopilots. Can anyone (preferably from TRUTRAC) confirm this.
Thank You
