Only one navigator working - mjblay - 08-12-2025
Hi, I just bought and installed TDS GTN Xi, and I'm trying to use it with X-plane 12 in the Carenado F33A. The screen of the GTNXi 1 remains blank, while the screen of the GTNXi 2 is displayed normally. This is regardless of which navigator (750, 650, etc) I choose for either unit. Also, the mouse context menu that changes the pointer to curved arrows or a hand doesn't work for unit 1.
The Laminar 172 works just fine with both units displaying normally. The Laminar Lancair has the opposite problem: unit 1 displays, but unit 2 doesn't display.
Is this a problem of the aircraft model only having one stock navigator? If so, is there any workaround? I bought the TDS GTN Xi primarily to control COM 1 in the F33A since Carenado's controls on the GNS 430 are basically unusable (the small knob increments three digits to the right of the decimal, so tuning in any frequency takes forever and is really not viable in PilotEdge). Also, my real life Bonanza V35 has a GTN 750 Xi and a GTN 650 Xi, so I'd love to fly a simulated Bonanza with both. Even if I could just fly with one navigator, I'd love for it to replace COM 1 in the Carenado F33A instead of COM 2, since the stock COM 2 dials are easy to tune.
Thanks for the help!

Hello,
Edit: It seems that the F33 packaged from the store where you have purchased it is missing a GTN integration ini file, which has to be manually added prior to running the TDS GTNXi for the Legacy VC integration to function. We would suggest that you contact us via Discord (DM @TDSSim) for the instructions.
As a first test, please access the XPlane Plugins Menu/TDS/GTNXi Unit 1 and from the settings tab please check/set the Power to Always On. You can also try this for the other unit as well.
Which antivirus are you using?
Also, please test the TDS GTNXi into the default C172 by bringing up both navigators and also let us know how it goes.
Do you have the Legacy VC feature enabled?
We would recommend taking this to Discord rather than the forum as we have an active community in our XPlane Community Support section.
Not to worry, we will do our best to assist you.
