[MRAviation]

my grand duke gtn xi screen is blank as is the flypad.  Hype H145 is also blank.  Carenado PC12 htn xi is blank along with avionics screens.

pms50 is removed from community folder.

Garmin trainer is v3.6.4 and gtn xi instrument installed is v30.20.

Hello,

Please try this and let us know how it goes:

With MSFS closed, start the TDS GTNXi Pro from the desktop shortcut, then click on the GTN750Xi button. Does the screen light up?

Are you running AVG/Avast antivirus?

Not to worry, we will get this sorted so you can fully enjoy the TDS GTNXi Pro!

Hi.  Yes with MSFS closed GTNXI Pro starts up immediately from desktop.  I can plan flights etc.
No AntiVirus installed.  Only Microsoft windows 11 protections.

If this helps earlier this week before I purchased TDS Pro I installed Garmin Aviation Trainer app V3.8.4.0.  Then two days later bought TDS Pro and started MSFS and tried to use it.  I then realized I needed to downgrade Garmin to v3.6.4.0.  I shutdown MSFS, removed Garmin trainer from settings/apps remove/install.  I then installed v3.6.4.0 from your TDS app.  Perhaps this cached something and conflicts?

Thanks

Very strange but now TDS Pro works on the 3 planes I tried. I did these very steps before I posted here to register Navigraph and check AIRAC cycle was current. A total mystery but it is working.
