This mod provides a non-interactive integration of the TDS GTN 750Xi or 650Xi screen into the cockpit.
It consists of to parts, first an MSFS addon that can replace any screen gauge in the VC, and second an App that captures the screen of the TDS GTNXi and feeds them to the addon.
There is no interactivity on the screen in the cockpit (meaning it is showing what the GTNXi screen shows, but you can not control it via the VC), this is intended as a visual reference and for immersion. You still need to control the GTNXi via its window, e.g. on a second screen or tablet.
With tuned settings I only have a small performance impact, not more than using any other complex glass gauge screen.
- Important! -
This solution is inferior in almost any ways to the native VC integration of the TDS GTNXi!
There is no interactivity and it will not integrate any functionality into the VC beside showing the image of the unit, so no features like the working GSI in the JustFlight planes which you would get with the native VC integration.
I strongly recommend to only use this mod if your setup relies on using running the TDS GTNXi externaly (like on a separate touchscreen) and popping out the VC gauge does not work for you.
- Installation -
- Unzip the download.
- Copy the content from the Community folder into the MSFS Community directory.
- The addon gtn-screen-relay is mandatory.
- Included are also reference integration addons for some aircraft, and you only need to copy those that you want:
- Just Flight PA28 Arrow (GTN 750Xi)
- Just Flight PA28 Turbo Arrow (GTN 750Xi)
- Carenado M20R Ovation (GTN 750Xi)
- Carenado PA44 Seminole (GTN 750Xi)
- Cessna C172 (stock steam gauge) (GTN 650Xi)
- Robin CAP-10 (stock) (GTN 650Xi)
- See further down in the Aircraft Integration section for instructions on how to create integration mods for other aircraft.
- Run GTNXiScreenRelay.exe from the "App" folder.
- The TDS GTN 750Xi or 650Xi window needs to be open and not minimized, but it does not have to be in the foreground. You can check if the relay is working by going to http://localhost:45783/GTN750 or http://localhost:45783/GTN650 in your browser. You should see a snapshot of the units screen (might not work on the first request, simply reload).
- For the Just Flight and Carenado aircraft you have to have them configured for GTN750 usage via their VC tablets.
- App Settings -
The app can be configured through various settings to optimize performance and quality.
All settings are applied "live", so you can easily tune them and also adapt them on the fly, e.g. increase the refresh rate when you have FPS to spare enroute and reduce it during takeoff.
- Image Format:
- JPEG High is recommended.
- While PNG has the best quality, it is larger and slower to process, resulting in a lower refresh rate.
- Refresh Interval:
- The interval in milliseconds between requests of a new frame. A lower value means a higher refresh rate.
- Setting this to 0 will limit the refresh rate only by the processing time and the sim frames.
- Scaling:
- The native resolution of the TDS GTNXi window is a main factor to performance. If you are displaying the GTNXi window on a high resolution device, like a 4K monitor or a high-res tablet, it can help sim performance to scale the image down. But as this introduces further processing on the app side, resulting in a reduced refresh rate.
- Due to that you will likely not see an improvement when you set it in the range of ~70-99%.
- Keep at 100% as a baseline.
- See the Performance Tips section below for better alternatives on high-res screens.
- GTN750/GTN650 Bezel/Hide Frame options:
- Those options reflect the equally named settings from the TDS GTNXi Flight Sim application. You have to set them to the same value to ensure the app can accuratly capture the screen area of the window.
- Start/Stop:
- With this button you can start and stop the relay.
- Performance Tips -
A main factor to the performance is the native resolution of the GTNXi window. To improve the performance beyond what is possible with the settings provided by the app you can try the following:
- Reduce the window size, if it is bigger than you need.
- Use the Windows 10 display settings to increase the scaling of the display you are displaying the GTNXi window on. This will reduce the native resolution of the window at the same apparent size.
- Reduce the resolution of the monitor you are displaying the GTNXi window on. For example I am using it on a high-res tablet using Spacedesk, and choosing 75% of the tablets native resolution in Spacedesk already gives a good boost in performance.
- Aircraft Integration -
You can replace any screen/gauge in an aircraft by creating a mod of the panel.cfg.
In the panel.cfg you only have to replace the existing gauge path with either NavSystems/gtn-screen-relay/gtnscreenrelay750.html or NavSystems/gtn-screen-relay/gtnscreenrelay650.html.
For example, to integrate the GTN 650Xi screen into the Robin CAP-10 as replacement for the GNS 430 screen simply create a mod and change the line
>> htmlgauge00=NavSystems/GPS/AS430/AS430.html, 0, 0, 350, 190
to
>> htmlgauge00=NavSystems/gtn-screen-relay/gtnscreenrelay650.html, 0, 0, 350, 190
Also use the other aircraft integrations from this mod as an reference.
Not working by me, I can see the frame of the GTN but no display

I just checked and it still working, and it would be really weird if it could capture the frame/bezel but not the content.
Have you checked the URL from the readme in a browser?

Unfortunately, unless I'm missing something, this doesn't seem to be working anymore.

Anyone care to sell me on this over the pms gtn750? I see some minor differences, but what's here that justifies making your gps unit non-interactable in game?

HI, has anyone created this for the Beech G36 plane yet? I'm a little confused on how to create a file myself.

great app and is an amazing companion for the awesome TDS sim software that brings a real Garmin GTN 750/650Xi unit to be used with MSFS, thanks a lot... great work... is a real game changer, highly recommended...

Hey noticing lower fps and mini stutters when viewing the aircraft from the outside but in the inside it's fine. This doesn't happen when the mod is in the community folder, only when the app is open

very smart idea, really adds a lot to the immersion to be able to see the device inside the plane due to the current limitations. Thank you !

Many thanks for this. I want to create a mod for the BN2 and was wondering how to create a mod. Thanks in advance.
