Hello,

We are sorry to hear that you are having problems, we are here to help.

In regards to the TDS GTNXI not working, let's approach this problem on a step by step basis. Please start the standalone TDS GTNXi from the desktop shortcut with MSFS closed and click on the GTN750Xi button, does the screen light up?

Additionally, are you running any external hardware from Honeycomb?

Based on your answers we will see how to approach this problem.
Not to worry, we will get it resolved!

yes - the screen lights up and shows the 2 small screens plus "sim not running"

yes! I have both Alpha and Bravo set ups - correctly set for each individual aircraft - only 750 not working

Hello,

Thank you for the image, can you please click on the GTN750Xi button from the interface (image above) and let us know if it lights up.
In regards to the Honeycomb hardware, a very frequent black screen problem is the avionics bus switch being set to off. Can you please make sure that the physical button is turned on?

Additionally, which antivirus are you using?

We will resolve the problem, in the worst case, we will attempt a version with logging.
