First off -- thank you to Jean-Luc for the insight into the workings and the application, and Bourrinopathe for the superb 3D model that I used and the PM's back and forth.

I don't have approval to distribute this by Airfoillabs and I like to respect designers wishes so until then it's not available.

What I can tell you is that it's not very hard to do! I was able to integrate the 750 with full buttons and knobs working; yes you can click on home or direct and the screen will respond.

I couldn't be anymore happier right now!

Couple things to note

• The volume knob for COM and NAV doesn't work quite right -- the plane itself is resetting the volume separate from the GPS.
• If removing the old GPS and manipulators; be very careful in your 3D app as you can remove ability to move the mixture levers with your mouse.

Hi, this is normal because you are using a GTN 725 which is a radio-less device. This device is documented in the RXP GTN User's Manual. 

Do you mean: "when I change the GTN CDI mode from GPS to VLOC, it doesn't change anything on the HSI"?

So how do I load the 750 into airfoillabs King Air as a single unit? I ask because @Ither mod on the X-plane forum does seem to have the 750 loaded as a single unit if I look at his thumbnails. Most probably I have done something wrong and would appreciate a little guidance. 

If you insert the gtn750 do you lose the ability to have weather radar?
