Good Afternoon.  I have a quick question.  Is it possible to slave Falcons Vnav autopilot function to GTN Vnav at the user level?  I am guessing Carenado's Vnav is mapped to a custom non XP default control so it does not work out of the box with GTN.   Unless it's a user error but I think I an doing the steps correctly. GTN TOD calculated and displayed on the map reduce ASEL to the lower altitude push VNAV button. 

Hi,

There is no possible link at this time between autopilot altitude and GTN flight plan altitude. I believe this requires a specific Garmin autopilot IRL too.
