  Import from Navigraph not working
Posted by: andrew - 06-16-2026, 02:54 PM - Forum: TDS GTNXi Flight Simulator - Replies (13)

Hi -

Trying to solve this puzzle... I'm unable to load Navigraph flight plans.

I'm using the in-game tablet, Navigraph > Export > Load as active flightplan, but nothing happens.

How can I troubleshoot this?

thanks

  Home and Direct to
Posted by: cinrac@gmail.com - 06-16-2026, 02:31 AM - Forum: TDS GTNXi XPlane - Replies (3)

I have the TDS GTN650xi setup on my thranda 172m in x-plane. Visually it looks like the old 650 and not the xi. When I press the home and direct to buttons nothing happens within the cockpit.  I also use air manager and when pressing the buttons (or the use the dials ) with their overlay nothing happens. When I press the buttons on the pop out it seems to work.

I have tried re-installing the TDS software and the thranda 172. I also tried other models with the gtn popped out with the same problem. 

I am not sure how to proceed to get the home and direct to buttons to work or to be able to use the rotary dials in airmanager.

  ETE and ETA L variables useless values
Posted by: Flight Engineer - 06-15-2026, 12:55 PM - Forum: TDS GTNXi Flight Simulator - Replies (1)

TDSGTNXI_TotalETE

The total ETE variable shows completely meaningless values. It should display the following:

  • ete to the last waypoint of the flight plan or
  • ete to the direct to wp

TDSGTNXI_TotalETA

The total ATA variable shows the current Z time.

It should display the following:
  • ATA at the last waypoint of the flight plan or
  • ATA at the direct to wp.

Tested with 2 aircraft. MSFS 2024 Cessna 152 and Carenado F33A
Test software: Airmanager

The corresponding A variables from MSFS also do not receive valid values. However, the GTN 750 from PMS can do that.

Any idea why this could be. The integrated fuel computer of the TDS GTNXi displays usable values. We only noticed it because we use a Shadin fuel computer in one of our  airmanager cockpit, which carries out the calculations based on the ETE. And the displayed ETEs and ATAs in the FP of the TDS GTNXi are also correct.

  STANDALONE
Posted by: Dave Wilson - 06-09-2026, 08:36 PM - Forum: TDS GTNXi Flight Simulator - Replies (3)

I have gtn750xi pro. I can not get standalone to work. I am trying to use it with a msfs 2014 c90GTx. When I start msfs when i get to the banner for your software it shuts down the screen for the gtn and turs it black. How to use with standalone mode?

Thanks for help

  Default AirSim3D Citation 560 and TDS
Posted by: mroushdy - 06-08-2026, 12:56 AM - Forum: TDS GTNXi XPlane - Replies (1)

Hello,

I understand that the mentioned aircraft (link below) has a variant with 2 TDS screens, howver, since TDS doesn't yet support the weather radar, would the pop-out work with the default version of this aircraft so we'd still leverage the default weather radar screen in the cockpit?

  Getting buggy and unreliable
Posted by: NickMDal - 06-06-2026, 09:55 AM - Forum: TDS GTNXi Flight Simulator - Replies (2)

Hi.  I'm using the RealSimGear GTN750 with your software.  Am flying FlySimWare Chancellor 414.

Airport maps do not appear or the momentarily appear regardless of the range setting.

Back button lights up but does not activate without a second or third press.

I reinstalled the Garmin software and did your recent update.  Any way to troubleshoot this?

  Octavi IFR configuration?
Posted by: kajimike - 06-04-2026, 08:09 PM - Forum: TDS GTNXi XPlane - Replies (2)

Hello,

I just got the TDS and using the 750 for Xplane and am using it with my VR controllers. That is ok but a bit cumbersome.  

Has anyone developed scripts for the Octavi IFR , either with Mobiflight or FlywithLua (or something else)?

Thanks for any tips.

  Com Frequency changes not showing.
Posted by: ArtFlyer - 06-02-2026, 05:58 PM - Forum: TDS GTNXi Flight Simulator - Replies (4)

Just a small issue I wonder if you can help? 

MSFS2024 Store, Win 11 VR (Pimax), Black Sqr Bonanza, sayIntentions.ai ATC

I used to be able to change the GTN 750 comms frequency by clicking the ATC UI, but this has now stopped showing.  The comm 1 frequency changes but the GTN 750 does not show the change any more.

Thank you and appreciated.

  SF260 problems
Posted by: Joerg - 05-28-2026, 02:28 PM - Forum: TDS GTNXi XPlane - Replies (1)

Hi all,

I have some problems getting the GTN to work in the JRollon SF260.

In the SF260 I can find no way to view the GTN in the virtual cockpit. The popup works fine but that is not what I want.


Thanks for your help.  Smile
