I have not bought The FA50 EX, and I guess I'm Lucky, but here is my two cents. Carenado is not listing to there customers. I wrote to them because on the XP11 FA50 ex version, they Offer F1 GTN 750 integration and cost is 39.95. However, on the FSX/P3d Version No Integration and it cost 44.95. SO I wrote to them on this issue and receive and answer that this was not in the works for this aircraft. So as for F1 GTN 750 navigation I guess you can use it of screen, but was the point.
