I am running x-plane 12/TDS GTN 750xi/LiveTraffic.
I see AI traffic everywhere, both on the ground and in the sky.

For some reason, none of the traffic is showing in the 750xi tcas traffic screen, or any screen for that matter.

Does anybody have this combination up and running with success?

Not sure how to troubleshoot this issue.

However i've only been able to integrate it into my Thranda Cessna Caravan C208. When I try to integrate it into my AFL King Air 350 im only able to open the Pop Up from the Plugins menu and XPlane still shows me the Laminar Garmin 430. 

I honestly also dont know how to integrate the GTN into Airplanes like the Torquesim SR20 Entegra or the King Air 350... 

Do you know if I have to have some kind of Config File to Integrate it into these Aircrafts?
Appreciate your help,

I’m running X-Plane 12 on Windows and recently purchased the AirfoilLabs King Air 350 and the TDS GTN 750, where I notice a consistent and quite significant performance hit.

Issue:
When I turn on the TDS GTN 750, I experience an FPS drop of around 15 FPS (raw, not frame-gen). The drop is immediate and consistent.

Details:

Aircraft: Airfoillabs King Air 350

Add-on: TDS GTN 750

OS: Windows

Simulator: X-Plane 12

FPS impact: ~ -15 FPS when GTN is in use

Observations:

FPS is stable and acceptable without the GTN 750

As soon as the GTN is turned on / displayed, FPS drops noticeably

The performance hit persists throughout the flight

No FPS drop observed with default avionics in the same aircraft

Question:
Is this expected behavior due to how the TDS GTN 750 is rendered (e.g., external process, CPU/GPU load), or could something be misconfigured on my side?

Any known tweaks or settings to reduce the performance impact?

Thanks in advance!]]>

When I click Power On in the Garmin Trainer Avionics Demos or Aircraft Trainers, everything seems to work fine there, but in XPlane when I do plugins > TDS GTNXi > GTNXi1 > Show Window the GTNXi750 window appears but is blank.  Same for GTNXi2.  My avionics are powered on (built-in GNS 530 is working).

I am using version 1.0.1.7 of the TDS GPS Manager.

Looking at the Garmin Aviation Trainer Launcher > Version Manager, I have version 3.10.3.0 of the Garmin Launcher (which was the version recommended by TDSGPSManager.exe), with version 21.3.7.0 of GTN Xi, version 20.42.2.0 of GTN Xi, and version 3.62.2.0 of TXi.  I wasn't sure from the instructions if there were specific versions of GTN Xi I needed to install.

Oddly, after attempting a re-install, the TDS GPS manager is showing that GTNXI PC Trainer is Not Installed, with Available Version: 20.42.2, even though the Version Manager in the Garmin Launcher shows 20.42.2.0 as installed.  Clicking Download and Install for GTNXI PC Trainer in TDS GPS Manager says to Please Select the Desired Component GTNXI Trainer, but the only active button available is the Back button.  I don't think I was seeing this odd behavior in my initial install.

I did a quick check with several of the built-in XPlane 12 planes and saw the same behavior, so I'm thinking this is not specific to my Just Flight plane.

I'm kind of stuck at this point (despite being a software engineer!).  I did try searching the forums; I tried reinstalls, reinstall as admin, etc. but might have missed something.   Any other diagnostic suggestions?

Thanks!]]>

I just bought this addon to be used on my X-Plane 12 (and hopping to be aided on my IR irl qualification), and I installed GTNXi 750 as Master and a 650 as secondary. When I try to open the settings for each one, nothing appears. I noticed however, one time that the page for the 650 has opened, I was able to see it, but after some seconds the settings window has freezed. 
Any thoughts about it ?

Thank you in advance

Update: I was still able to change the ini file to power the GPS1 on BUS 1 and GPS2 on BUS 2 without the need to use the settings page inside the sim]]>

Much better than RXP I must say, though a little more blurry.

Got some questions:
1.Where the file containing user waypoints is located? I wanna make a backup of this file cause I have to make many waypoints as airfields - I have plenty small private arfiels made by me.
2. Is there any way to subscribe info about eventual updates of TDS GTNXi? How should I know about them?

I am using the TDS GTNXi 750 in Xplane 12.
I purchased the Navigraph data base subscription and updates both Xplane 12 and TDS 750 using the Navigraph FMS Data Manager. After doing so, this is the opening Database message I get from TDS GTN 750 when starting a flight.

Is the Yellow text warning me of the activation date normal?
Also, the other databases  safetaxi and Obstacle databases  expired in 2024. IS this normal too?

I have attached the Database screen for reference.
