GTN750Xi & GTN650Xi Blank Screens - GordonNG - 07-20-2026
Hello,
So both the GTN750Xi and 650Xi have blank screens. I have tested both on the Black Square Duke and the single 750Xi on the Carenado 182.
The TDS GTNXi Flight Sim app (ver 1.3.1.5) is also a little buggy for me, I can only access the Avionics page, where the 750Xi and 650Xi both show blank screens.
I cannot open the Settings or Navigraph pages (even though I have the pro upgrade)
Along with that app, it does show when connected to MSFS2024 though.
Regarding the Garmin trainer package, the trainers work fine, they pop out and begin their demo.
As read on a different thread, I took a flight around the block to gather some logging, however the log does not show more granular info, just that the sim was started and that it ended.
Antivirus whitelist has been configured, I added both the Garmin trainer and the TDS folders to the exception list.
Not sure what else to do.

Hello,
We recommend downloading a new copy of the TDS GPS Manager from the TDS website, reboot the PC, then reinstall the TDS GTNXi Pro V1.3.1.5 (not the PC Trainer).
The GTNXi screens should work well after this. Please let us know how it goes.
