Warning: Before installing the Device Interface for Microsoft Flight Simulator 2020 or 2024, please make sure you have run the simulator first. This will allow Microsoft Flight Simulator to build the files and folders necessary for the installer to locate. After your first run of Microsoft Flight Simulator, please close the simulator and then you can install the device interface.
To install command mappings for TDS GTNXi:
During the installation you will be prompted to select the components to install:
This is the point where you will have the option to install a command mapping file that will allow your RealSimGear GTN750/650 to control the TDS Simulations GTNXi software.
Use the dropdown menu to choose between the PMS50 GTN or TDS GTNXi Command Mapping files. This choice only effects the GTN750/650 command structure. It does not effect the operation of the G1000 devices!
OR
Only one version will be installed. If you wish to change GTN software versions, simply re-run the MSFS Device Interface Installer and select a different version of the command mapping file.

Additional Software
Driver for T6 USB3 Display Adapter
PenMount Touchscreen Driver (for legacy touch screen devices)
Warning: The PenMount Touchscreen Driver is for older versions of our GTN 750 and 650 hardware that have a hard wired USB cable coming out of the rear of the device. If your GTN does not have this extra USB connection, please do not install the PenMount Driver as your touch screen is natively supported through the Windows Tablet PC Settings app.
