Whenever I load into a flight using MSFS 2024, I notice that three instances of GTN Simulator (32 bit) are running in Task Manager. This appears to cause the GTN display to double up and flicker. For me, the issue occurs with the default C152 using the default MSFS 2024 add-on integration. If I exit FS2024 two of the processes disappear but one remains, and therein if I restart FS2024 and load into a flight the problem is still there. The only fix is to go into task manager and delete one of GTN Simulator (32 bit) processes.

I'd appreciate any suggestions or troubleshooting steps to help identify the cause and resolve the problem.

I'm using the TDS GTN 750Xi and GTN 650Xi (version 1.3.1.5) as standalone units on a separate touchscreen monitor with the A2A Comanche in MSFS 2024. Everything works nicely, but the units are always powered on as soon as I start them, regardless of the battery or avionics master switch positions. I'd like them to power on with the avionics master switch instead.

I've already changed the value of "Elec.Power.Source" to 2 (which should be the AvionicsBus option) in the corresponding .ini files, but the units still power on regardless.

Does anyone have an idea how to fix this?

When running the units outside of the MSFS2024 they operate correctly just like they do in the Garmin Trainer App.

Does anyone know of a fix for this behavior?]]>

After starting up my GTN units I get a TAWS failure followed by the following message:-

" Terrain/TAWS configuration is invalid. GTN needs service"

Can someone explain please and how to cure it.

This only happens when the Navigraph navigation data is installed on the TDS. Using the default data that comes with the Garmin Trainer or using the Navigraph data inside MSFS2024 with for example the PMS50 works fine.

I am flying the Black Square TBM 850 with GTN 750 from TDS GTNXi Pro in FS2024.

With the ILS 25 approach loaded from EDDS (Stuttgart/Germany) I am flying towards the waypoint CI25 (before FAF UNSER) in heading mode with the approach armed.
ILS frequency ( 109.9 ISTW) is active in NAV1.

See picture 1 before reaching the extended centerline of RWY 25.
(Remark: The APR button of the autopilot was pressed shortly after this screenshot, so please see this picture as if the APR button would be armed already).


  Picture1.jpg (Size: 571.83 KB / Downloads: 8)

The problem is, that the aircraft passes the extended centerline without capturing the glideslope (see picture 2).


  Picture2.jpg (Size: 561.13 KB / Downloads: 2)

Sometimes, it works and it captures localizer and glidepath, and sometimes not?

Any idea, what is going wrong?

Thanks a lot!

I am using the MSFS 2024 with the Black Square Dukes and I am havign problems with the flight plan page. The destination airport shouldn't stay in the end of the flight plan ? To me it stays in the middle and that makes the plane go first to the destination and just after that going to the initial fix of the profile. I tried a lot of things and probebly I am forgeting something silly, but still need help.

Thank you.

Just purchased the pro package. I received the confirmation email, but the account page still shows I have no product, and there's no download links.

Aviation trainer: 3.10.3.0
GTNXi PC Trainer: 20.42.2.0
FS 2024
Executable 1.3.1.5
Gauge 3.0.6

Two defender rules, one for the roar service and one for the app itself.  Made both inbound and outbound rules.

Upon starting the avionics I get the infamous black screen.

This works randomly and nothing consistent fixes it.  

The solution as I read with others cannot keep being reinstall the application using TDS GPS Manager running as admin.  Please provide better troubleshooting.  People don't have hours and days to "fix" their setup just to use the sim for a hour or two.

This is beyond frustrating because for no rhyme or reason it sometimes works.]]>

I am now trying to bring the GTNXi into the cockpit of the Black Square Velocity XL, which is a compatible aircraft for the GTNXi but the center avionics screen is blank.  There does not appear to be any options in the aircraft mod to activate the GTNXi.  Do I need a folder similar to the first one listed above for the Velocity XL?

Thanks

PS: I had the Velocity XL previously with the PMS version of the avionics.  I deleted that and downloaded the TDS version.  This is when I discovered the GTNXi was not loading.

UPDATE: ISSUE SOLVED.  I FOLLOWED THE SUGGESTIONS IN ANOTHER POST AND ALL IS WELL.]]>

At ENBR, Navigraph Charts contains the ADADI 2C/2D RNAV COPTER departure, including ADADI 2D.
However, when selecting PROC → Departure → ENBR in the GTNXi, the ADADI helicopter departures are not present at all.
Could you please confirm whether helicopter departures at existing airports such as ENBR are currently supported by the GTNXi Pro, and whether this is a known navdata issue?
I can provide screenshots of the GTNXi database information and the Navigraph chart if required.

There is no obvious way to see if the Garmin Trainer is installed.
It will not work on my new 2024 install if the SIM is not running.

... And this forum is awful.

... And you want me to pay another 30 Euros
For the Pro version ?

Lol.]]>
