I'm using the TDS 750/650 in crossfill and the Black Square Baron has a specific gauge for NAV2, which would be very useful as a backup for VOR and ILS.
Using the 750/650 pair, I can't connect another specific receiver to the NAV2.
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 ?

X-Plane 12.4.1 and using the integration files for the default C172


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]]>

Originally, I was having issues with FPS dropping from over 100 to 10 or less into an hour long flight, but I don't think it was an TDS GTNXi issue. Troubleshooting got me no answers, so reinstalled Windows 11 and FS 2024 to a cleanly formatted SSD.

With a fresh install of Win11/FS24, I started to install plugins. After installing TDS GTNXi, I noticed I can't Pop-Out the window. When I press the r/Alt key and left click there is sort of a flash across the unit, but it does not pop out. I tried this with several other aircraft using the TDS unit but the same thing is happening in all other aircraft. When I try the PMS or Asobo Pop-Out, the window pops out just fine, leading me to think this is a TDS issue.  I've never had any issues previously with the TDS unit and I've been using it for at least 5 years, at least nothing like this. I also made sure the package in my community folder is Enabled. I did find it odd that the instrument version says 0.0.0.0 (see attached screenshot) 

MSFS 2024 version: 1.6.3.4.0
TDS Install Manager: 1.0.1.7  (I am using the Pro version of the unit)
Aviation Trainer: 3.10.3.0
GTNXi Trainer: 20.42.2.0
FS24 Guage: 3.1.3
I use a RealSimGear GTN750 monitor and GFC500 autopilot unit: 2.1.2

64GB Corsair RAM

Thanks for any help.

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've tried several flight plans with different airports as origin and destination, but the map screen is always fixed on KJFK.
Curiously, on the "Preview" screen, the application correctly displays the flight plan and the chosen procedures.
The Navigraph database is up-to-date and functional.
This issue doesn't occur in the onboard version of TDS, where the map screen correctly shows the aircraft's position.
Is this the expected behavior in the desktop version of TDS?
For better understanding, I'm sending some snapshots of the issue.

Before starting MSFS 2024, I launch TDS GTNXi Pro. Failing to do that always results in a black screen and the Garmin doesn't work.  During the loading of MSFS 2024, a splash screen pops up for TDS GTNXi Pro. When the splash screen loads, the entire directory C:\beyondATC is deleted. I tried moving the file to d:\beyondATC\beyondATC.exe and it works fine until an update is needed. BeyondATC can't seem to update properly in the locaiton on D:\beyondATC.  

I have reinstalled both beyondATC and TDS GTNXi Pro, but the problem persists.  As long as I move the ATC program it works.  If I uninstall  TDS GTNXi Pro and run without it, c:\beyondATC doesn't get deleted.  So based on that, it sounds like there is some cleanup code to remove beyondATC for some reason.  The install of beyondATC doesn't give you any option other than c:\beyondATC so I can't have the installer put it somewhere else.  Can you check to see if there's some extra cleanup code that can be removed?

Thanks.]]>

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.

I've recently noticed (not sure if it was present before, but I don't think so) that I observe stutters when using TDS GTNs. I haven't been using my sim for some time (month or so), then bought new C208 Pro from BlackSquare. Before first flight I noticed an update of GTNXi is available, so I installed it. And I started to observe those stutters during that first flight.
It happens in various aircraft: new C208 Pro, BlackSquere TBM 850, default C172 with cockpit mod.
Stutters are not constant - I have 30-40 sec of fluent flight, then stutters for around 10sec... 
When I change gps to some different option (blackSquare allows this even mid-flight), then stutters disappear, that's how I came up it's issue with GTNXi.
It doesn't matter what region of World I'm visiting, I tried even over middle of Atlantic with no terrain in vicinity.

I added processes to Win defender exclusions
  TDS_exclussions.png (Size: 13.5 KB / Downloads: 3)

Also, Hardware-Accelerated GPU Schedulling is set to OFF.

Any idea what might be causing these? Any way to investigate on my side?
Unfortunately it's a showstopper, when it happens during take-off or landing it's not possible to control aircraft properly.

Paweł Dragan]]>

I'll try to provide as much information as possible so we can find a solution together.
MSFS 2024 v.1.7.16.0
TDS Aviation Trainer version 3.10.3.0
GTNXi PC Trainer version 20.42.2.0
Executable version 1.3.1.3
Gauge 3.0.4
Pro Upgrade: included
Aircraft: Black Square A36 Bonanza PRO 0.1.1a (last version)
Flight charts: Navigraph full, AIRAC Cycle 2603 rev.3 with TDS SIM SOFTWARE updated via Navigraph Hub

I'm a doctor, and also a professional pilot, and I have a lot of experience with IFR flights.

I often use MSFS and TDS GTNXi PRO for training.

The TDS GTNXi PRO performs the GPS flight plan very well, except when it comes time to execute ILS procedure for the selected RNW, loaded and activated.
The TDS recognizes the RNW ILS frequency in the active NAV window, even displaying its correct identification, but in the moment the VLOC is activated, the IFR navigation is completely disabled (the red NAV flag appears on the artificial horizon).
Since the TDS takes over all IFR navigation and controls, there is no way to activate an alternative NAV 2 to perform the landing, which needs to be aborted.
For your information, the TDS performs RNAV landing procedures without any problem, this difficulty its restricted to the ILS.
As a test, I installed the PMS50 GTN750 on this same aircraft, and this system performed the same ILS procedures flawlessly.
I verified this problem at many airports in Brazil (SBGR, SBSP, SBKP, SBGF, SBGL etc.)
Any solution?
Thanks
