There was already an old long discussion about this problem, I know and I read it. 
However, as the discussion is about two years old, I guess it's not relevant anymore for the latest X-Plane version.
Carenado Citation II doesn't capture GS, NAV and APPR switch to ARMED and stayed in ARMED state if I change on GTN 750  CDI from GPS to VOR1. The GLS frequency is set correctly. 
Remove the GTN 750, APPR mode works properly.

Install the GTN 750, the APPR light stays yellow and the plane never intercepts the glideslope.
Running 11.50b11 of X-Plane 11.

Hi,

Are you sure the GTN is set to "Pilot" side in the GTN Settings Panel?

Can you please post the content of the RXP log files? (see user's manual for file/path)

Hello,

as I miss the attach media button,

here the rxpGTN.xpl.log file:

 

20/06/19 19:31:26.181 05208 -    ] # win.xpl version 2.5.25.0
20/06/19 19:31:26.181 05208 INFO ] 
 

and the rxpGtnSim.dll.log:

20/06/19 19:31:28.218 05208 -    ] # rxpGtnSim64.dll version 2.5.25.0
20/06/19 19:31:28.218 05208 INFO ] 

The Settings page in simulator:

GTN 750 1

you're not using the latest GTN version:

The settings have a scroll bar to the right of the window and there are much more settings than that. The one I'm specifically asking for is the Pilot/Copilot side.

Thanks a lot  for your help, I'll update asap. 

I purchased your GTN 750/650 at F1. They have a rather confusing agent, I couldn't find a possibility to updating, just for reinstalling. I don't know, is it reinstalling the same old version 2.5.25.0 or the last update? Do I use up an activation or not?

Can I update my 2.5.25.0 version on your support page?

why not using RXP plugin menu "check updates..."

Sorry, I found it a few minutes later.🙂
