Yep..I think maybe because the VR improvements might have been made to the initial release of the Do228? I think the Do228 is now at version 1.2 (did that add the switch for the GTN compatibility?) - anyway..I have the same problem. The VR improvements are awesome with the working rotary knobs and stuff, but if I hit the switch on the pedestal to switch to the GTN 750 - the 3D model changes to the GTN, but there is no power to the avionics or GTN.
I would love to see the VR mod updated to support the 1.2 version of the aircraft - any chance of that?
