Is there any way to enable this plane to follow a GPS flight plan?  When I use the PMS50 as an external autopilot, the Nav function never activates.  Altitude and heading holds work fine, but not Nav.  It’s really needed for those long over-water flights.

Edit:  There appears no way in MSFS 2024 but in 2020, the PMS50 external autopilot captures the flight plan and enables the Nav mode to be activated.  So back to MSFS 2020  for the Pilots B314!
