Before You Start
Before you begin the setup of your RealSimGear GTN 750 or GTN 650, you will need to complete the following items before connecting the device to your computer:
Install the RealSimGear Plugin
You will need to download and install the current version of the RealSimGear Device Interface for Microsoft Flight Simulator 2020.
Note: You will not need to install the optional touch screen drivers.
Install 3rd party GTN software
If you have not done so already, you will need to purchase, download, and install the TDS Software GTNXi Avionics software for either the GTN750, GTN650 or Both devices.
Additionally, Microsoft Flight Simulator 2020 has a second option for GTN Software from PMS50. The PMS50 GTN software runs internally to Microsoft Flight Simulator 2020 and uses internal navigation data. It is also available as a free, basic version, or a premium Paid version.
Each version of the GTN software has its strengths and its weaknesses. For ease of integration into any aircraft in Microsoft Flight Simulator, RealSimGear recommends the TDS Simulation GTNXi Software.
Mounting your GTN to a RealSimGear Desktop Stand
The RealSimGear GTN 650 and GTN 750 can be mounted in a number of ways. The most common method of mounting will be through the use of a RealSimGear Desktop Stand (Sold Separately).
Included with your RealSimGear GTN, will be a small plastic bag containing four, M3 self-tapping screws. These four screws will be used to secure the GTN to the stand in the four holes depicted in the images below.
Note: Install the screws with a hand screwdriver (#2 Phillips Head). Overtightening the screws can strip the mounting holes or effect operation of the devices.
The images above show the GTN devices being mounted in a single device mount. If you have purchased a GTN combination mount, the method of installation will be the same, as the cutout patterns in the combo stands are the same as the single device stands.
Connect the cables (Covers both the GTN750 and GTN650)
Connect the cables in the following order:
USB A to USB B: Connect the square Type B connector to the back of the GTN and the rectangular Type A connector to an available USB port on your PC or Powered USB hub.
HDMI: You will need to supply one HDMI cable (not included with the GTN), to connect from the GTN to your PC's graphics card or RealSimGear USB3 to Dual HDMI Adapter. If you are connecting directly to the graphics card, it is acceptable to use a good quality DisplayPort to HDMI cable.
Note for GTN650 Customers: You can use the 90 degree HDMI connection to allow proper cable management with the side mounted HDMI port.
12 Volt DC Power: Plug the barrel connector into the GTN unit, then plug the adapter into an available wall outlet.
For international customers: you can use an outlet adapter to adapt the North American plug style to your local plug style. Additionally you can also purchase a dedicated DC adapter to your plug style from a local electronics retailer.
Note for GTN650 Customers: The DC power port is located on the side of the GTN unit below the HDMI connector.
Note: The spare USB Type A connector on the GTN750 (above and to the left of the HDMI port) is not used. Please refrain from plugging anything into this port.
Configuring the Display and Touch Screen
With your GTN now connected to your PC and powered on, you will need to configure the screen settings and let Windows know that these devices have a touch screen.
We have created a full guide on the process and steps needed to fully configure the display and touch screen in the article linked in the button below.
Note for the GTN650 Customers: Unlike the GTN750, you will not need to flip the display in Windows Display Properties. You will only need to set the (Recommended) display size which is 1920 x 1080 in Windows Display Properties, before activating your touch screen.
With the display configured and your touch screen mapped with Windows Tablet PC Settings you are now ready to proceed to Microsoft Flight Simulator 2020 and continue to configure your avionics.
The following section is presently under development and will be updated as soon as possible. We appreciate you patience and apologize for the inconvenience.
• By default, the GTN750 will appear as COM/NAV1 and the GTN650 as COM/NAV2 in the connected devices window of the RealSimGear Plugin/Add-on. When you turn the knobs or press a button, the ‘message’ and ‘command’ sections will change accordingly.
NOTE: If the GTN650/750 buttons and knobs are not working, please check to make sure the device shows up in the RealSimGear Plugin/Add-on Connected Device interface and that you have selected the correct GTN Device Type that matches how you have configured the TDSSim or PMS50 GTN.
GTN 1 = Device Type COM1
GTN 2 = Device Type COM2
