Installation of the Pro Upgrade is automatic, as part of the TDS GTNXi Flight Sim version 1.1.0.0 (or higher) and the TDS GPS Manager version 1.0.1.1 (or higher) We recommend downloading the latest TDS GPS Manager from the My Account section of the TDS Sim Software sales website: https://tdssim.com/Account/login If you have a previous version of the TDS GTNXi, just use the Upgrade/Reinstall button on the TDS GPS Manager. The image above shows a correctly installed Pro Upgrade, the status Installed being displayed below the Installed Version. In addition, the TDS GTNXi Main Interface displays the Pro Upgrade installation status on the left side, right below the NAVIGRAPH CHARTS tab, as shown in the images of the next section. 9 Updating and using the Navigraph navdata The TDS GTNXi Pro Upgrade offers support for Navigraph navdata, so you will always be able to fly using current navdata. There are no limitations to the Navigraph navdata as opposed to the already supplied TDS GTNXi navdata, which will ensure that the best possible experience is offered to TDS GTNXi users. Important Note: An active Navigraph Unlimited or Navigraph Basic subscription is required, which can be obtained from: https://navigraph.com/ The TDS GTNXi comes preloaded with the Navigraph AIRAC cycle 2302 (February 2023). Updating to the latest AIRAC cycle is performed from the Navigraph Hub, which can be obtained from here: https://navigraph.com/downloads After downloading and installing the Navigraph Hub, the TDS GTNXi is found in the Microsoft Flight Simulator - Installed outside Simulator tab Important Note: In order to update the navigation database in the TDS GTNXi, both the TDS GTNXi as well as Microsoft Flight Simulator needs to be closed. 10 Upon startup of the TDS GTNXi, the database loading takes about 10 seconds, during this time the TDS GTNXi screens will be black as well as the TDS GTNXi interface displaying the information that the Navigraph database is preparing. After the database has been loaded, the correct AIRAC cycle can be confirmed from the startup - Database Info page, as pictures below. 11 The top row of the database info will change to Navigraph DB if the Navigraph navigation database is used and has correctly loaded; if the PC Trainer database is used, the database name is: Navigation If the TDS GTNXi is already started and in the Home page, the database cycle can always be confirmed from the System - System Status - Database Info section. Even though navigation databases do not expire or automatically disable themselves in the TDS GTNXi, we strongly encourage using up to date navigation data for the best possible experience. The location of the Navigraph database is: C:\Users\%username%\AppData\Roaming\TDS\GTNXi\Database\MSFS Where %username% is your username. File name: NavigraphDB.dat By manually renaming/removing the NavigraphDB.dat file, the PC Trainer database will be used. This process must be performed with the TDS GTNXi closed. 12 Connecting to Navigraph Charts Connecting to Navigraph Charts needs to be done via the TDS GTNXi main interface, NAVIGRAPH CHARTS tab, as pictured below. Important Note: An active Navigraph Unlimited subscription is required, which can be obtained from Navigraph: https://navigraph.com/ There are two connection options available: scanning the provided QR code with a phone/tablet and then logging in to the Navigraph Account or clicking on the link to the right side and logging in to the Navigraph Account, then approving the TDS GTNXi. The connection code is provided in case a manual input is needed due to unforeseen circumstances, but it should not be used as the link generated by us contains all this information, in order to facilitate a connection to Navigraph. Once a connection to Navigraph has been established, the NAVIGRAPH CHARTS tab will display the Navigraph logo as well as the current charts cycle. The connection token is saved between TDS GTNXi sessions, so there is no need to reconnect each time you start the TDS GTNXi. The time that the connection token can be used depends on the Navigraph server. 13 The Chart Selection option on the bottom of the interface allows for selection of the default FliteCharts, in case the user does not have a Navigraph Unlimited subscription. While we strongly advise using up to date navigation data and charts, this option is available for those wanting to use the provided North American FliteCharts. While the selection between the two options can be done in flight, we recommend making the selection before flight and keeping the selection within the flight. Important Note: As in real life, charts can only be displayed on GTN750Xi units. The 650Xi units being smaller in size, do not support charts. 14 Running the TDS GTNXi and Connecting to Flight Simulator Once the TDSGTNXi for Flight Simulator 2020 or 2024 has been installed, a shortcut will be placed on the desktop, which can be used to start the TDS GTNXi. If you are going to use the TDS GTNXi in the Virtual Cockpit as an integrated solution, there is no need to start the standalone desktop shortcut as the startup processes are done automatically by Flight Simulator. At the moment, it is not possible to run both standalone as well as Virtual Cockpit Integrated at the same time. Additionally, a shortcut is added in the Windows Start Menu, under the folder name TDS. The TDS GTNXi and Flight Simulator must run on the same computer as Flight Simulator; the connection will be established automatically, as soon as Flight Simulator is running in Flight Mode, there is no user intervention needed. Maintaining Audio Sound when Flight Simulator is not the active window To maintain Flight Simulator sound when the window is not active, please follow these instructions: With Flight Simulator loaded on the main menu startup screen, go to the Options tab, GENERAL, then select SOUND. Make sure that "MUTE AUDIO IN BACKGROUND" is set to OFF. 15 Interface Features The TDS GTNXi Flight Simulator interface is split into two tabs: ● Avionics Tab ● Settings Tab On the bottom right of the interface is the Flight Simulator connection status. A green indication with the text: “Flight Simulator is connected” means that the TDSGTNXi is communicating properly with Flight Simulator. A red indication with the text: “Flight Simulator is not running” means that the TDSGTNXi is not communicating properly with Flight Simulator. 16 Avionics Tab This tab lets you show and hide the respective GTNXi window, either GTNXi 750 or GTNXi 650. Both units can be shown and used in flight, in parallel. Clicking on the GTN750Xi button will display a second window which shows the GTNXi 750 Clicking on the GTN650Xi button will display a third window, which shows the GTNXi 650 17 Settings Tab The TDSGTNXi provides you the option to customize the product to best suit your specific needs. General Page settings: ● Navigation Source Selection ● RealSimGear Hardware Compatibility The settings for each unit are split into two types: ● Flight Simulator specific settings ● Device Settings All settings can be configured from the User Interface, Settings Tab or from the INI File. We suggest that you configure them from the User Interface. The location of the INI File is: C:\ProgramData\TDS\GTNXi\FlightSimEXE\TDSGTN.ini 18 Checking the box RealSimGear Hardware Compatibility provides compatibility with RealSimGear hardware GTNXi Selected Unit to Configure 19 Flight Simulator specific settings Connect GPS to Autopilot Provides the ability to send roll and pitch commands to the Flight Simulator Autopilot when the VLOC/GPS switch is in GPS Mode. There are two autopilot driving options: ● NAV = using the autopilot navigation mode (NAV and APR buttons), the preferred method because it provide glidepath support for LPV approaches ● HDG = a fallback state that drives the heading bug, it does not provide glidepath support for LPV approaches Radio Selection Provides the ability to select between COM1/NAV1 and COM2/NAV2 Connect GPS to HSI OBS (auto-slew) Checking this box correlates the MSFS HSI OBS Source with the GTNXi Course, whenever a new waypoint is being entered. Connect GPS to VOR# OBS Checking this box gives you the ability to change the OBS value of the GTNXi by using the Flight Simulator VOR CDI knob. The VOR source (VOR1 or VOR2) can be selected from the VLOC Source setting below. With the box unchecked, you can change the GTNXi OBS value using the on screen type-in pop-up 20 Device Settings Digital Fuel Computer Provides external sensor fuel data to the respective GTNXi unit Air Data Computer Provides external sensor air data to the respective GTNXi unit CDI Key Selects the display of the CDI key on the map page. If no CDI key is displayed, the respective GTNXI unit will default to GPS.

The TDSXi provides you with the ability to select the GPS Navigation source to drive the autopilot. The current options include: ● TDS GTNXi 750 Unit 1 ● TDS GTNXi 650 Unit 1 ● Flight Simulator GPS The active Navigation Source is displayed on the main TDS GTNXi interface, SETTINGS tab. The message “Navigation Source: Undefined” is displayed when there is no connection to Flight Simulator. To cycle between the available navigation sources, push the invisible button located on the top right corner of the GTN750Xi or GTN650Xi, as shown below: 23 Other Configurable Settings Setting a custom transponder VFR Key code in the Transponder Page Setting a custom transponder VFR key code is done via the INI file, which is located here: C:\ProgramData\TDS\GTN\FlightSimEXE\TDSGTN.ini To change the code for the desired unit: GTN750.1 or GTN650.1, please add this line: Transponder.CustomVFRCode = 7000 Please note, the Transponder Settings option from the Main Interface / Settings tab must be set to “INI File”, the corresponding ini file setting is: Transponder.VFRCode = 0 The range of the Transponder code must be from 0000 to 7777, with all digits starting at 0 and ending at 7. This means that the GTNXi will not accept any values of 8 or 9 in any digit places! 24 User Checklists The GTNXi supports an electronic version of your aircraft’s checklists. Checklists are stored in groups and as you complete a checklist item, you can advance to the next one. When the GTNXi automatically detects the presence of a checklist file (checklist.ace), the Checklists key appears in the Utilities page: Checklists are created using the Aviation Checklist Editor, found online at this link: https://www8.garmin.com/support/download_details.jsp?id=5075 The file called checklist.ace must be saved in this location: C:\ProgramData\TDS\GTNXi The GTNXi will automatically load the user checklist on startup. 25 Custom Flight Plans The GTNXi supports custom flight plans. The method is similar to importing flight plans from a datacard. They permit the user to create custom flight plans using flight planner tools and save them to separate files, which are used by the GTNXi. These flight plans can be previewed, activated or stored inside the GTNXi Flight Plan Catalog. The flight plans must have the file format: .gfp and are stored at this location: They are stored in this folder: C:\ProgramData\TDS\GTNXi\FPL Upon installation of the TDS GTNXi, a FPL folder will be created automatically containing a sample flight plan from CYOW to CYTZ, thanks to community member Les O’Reilly: https://www.youtube.com/c/LesOReilly Please note, the TDS GTNXi requires at least once flight plan to be available on startup, for the important button to become active. Subsequent flight plans can be added while in flight, without having to restart the software/individual unit. A flight plan is already provided with the TDS GTNXi installation, to facilitate the ease of inserting additional flight plans, during flight. We suggest that users keep at least one flight plan file in the FPL folder. To activate a flight plan in the GTNXi, from the Home page, access the Flight Plan page, then click on the Menu key. Then access the Catalog function, then click on the Menu key. A pop-up menu should appear with an Import key. Clicking on the Import key will display a list of all .gfp flight plans stored in the FPL folder. Select the desired flight plan to preview it, then you have the option to Store it inside the GTNXi’s flash memory or automatically Activate it, so it can be flown. Note: There is a maximum of 50 .gfp files that can be loaded from the FPL folder. This is a real life feature of the GTNXi and the TDS GTNXi abides to this. We suggest keeping the folder to a maximum of 50 files for the FPL folder. 26 User Waypoints The GTNXi supports the ability to import user created waypoints from a file. The method is similar to importing user waypoints from a datacard. Each user waypoint will have a name, latitude longitude and optional comment. Note: If a user waypoint is within 0.0001 degrees of latitude and longitude of a GTNXi database waypoint, then the GTNXi’s database waypoint will be used. To create a user.wpt file, open a spreadsheet program and each row contains an individual entry. Column A: Waypoint Name Column B: Comment Column C: Latitude (decimal degrees) Column D: Longitude (decimal degrees) The file must be saved a .csv file (comma separated values), then renamed to user.wpt The file called user.wpt must be saved in this location: C:\ProgramData\TDS\GTNXi To import user waypoints, from the Home screen, press the Waypoints key to access the Waypoints page. When the GTNXi automatically detects the presence of a user waypoints file (user.wpt), the Import Waypoints key automatically appears: Click on the Import Waypoints key to automatically import the waypoints, which will be imported in the User Waypoint page. 27 MSFS 2024 Default Aircraft Integration Starting with version 1.3.0.0 of the TDS GTNXi, the TDS GTNXi Pro/Pro Upgrade can be fully installed and used as a VC integration option in default MSFS 2024 aircraft, as part of the innovative MSFS 2024 feature: SimAttachments. We would like to thank TDS GTNXi community user Marc (Discord @marcfsx) for coming up with this innovative idea and for creating both the SimAttachments as well as the aircraft integration community mods! The default MSFS integration contains of two parts: 1) The SimAttachments for the 750Xi and 650Xi bezels 2) The individual aircraft mods, which are installed in the MSFS 2024 Community folder Installation of the SimAttachments is performed automatically by the TDS GPS Manager. Important note: TDS GPS Manager version 1.0.1.5 (or higher) is required for the installation of the SimAttachments. This can be confirmed by the Flight Simulator 2024 Gauge version 3.0.0 (or higher). The MSFS 2024 Community folder names are: marcfsx-instruments-tdssim-gtnxi750 marcfsx-instruments-tdssim-gtnxi750 Installation of the individual aircraft mods require the above mentioned SimAttachments, otherwise the default MSFS 2024 aircraft could not display in the MSFS aircraft selection. On initial feature release, there is day one support for: Cessna 185 Skywagon (GTN 750 Xi and GTN 650 Xi) Cessna 404 Titan (two GTN 750 Xi units) Cessna 172 Skyhawk Classic (GTN 750 Xi and GTN 650 Xi) Airbus H125 Helicopter (GTN 750 Xi and GTN 650 Xi) With these mods planned after initial release: DA40, PC6 Gauge version, DV20, C152, Twin Otter, C207, V35B Bonanza All the initially released mods feature dual GTN Xi support so users can take full advantage of crossfill. The MSFS 2024 default aircraft mods can be downloaded from the TDS Sim Software website: https://www.tdssim.com/ProUpgrade/msfs2024mods Disclaimer: The SimAttachments as well as the community mods created by marcfsx do not impose any warranties or liability of any kind, they are to be used at your own risk. 28 Crossfill Starting with version 1.3.0.0 of the TDS GTNXi, crossfill is fully supported in the TDS GTNXi Pro/Pro Upgrade. Crossfill allows the ability for two GTNXi units to communicate with each other, exchanging important information. Crossfill has been developed at the aviation-level of detail, thus offering a real-life experience to the TDS GTNXi! There is a general mis-understanding that only the active flight plan is crossfilled between the two GTNXi units, at least 15 items are crossfilled between the two units. Information crossfilled between units includes: Active flight plan Flight plan catalog User-Defined COM/NAV frequencies User waypoints Nearest airport criteria Units(Nav angle, fuel, temperature) COM channel spacing CDI scale ILS CDI capture settings More information on crossfill items can be found in the real GTN Xi manual. To check the crossfill status and disable crossfill, you can always access the Home/System/Status Crossfill button Crossfill is enabled by default and disabling crossfill in one unit will automatically disable crossfill in the second unit. Re-enabling crossfill after making flight plan changes in one unit, will overwrite the flight plan in the opposite unit. System message alerts are enabled by default, as a GTN Xi interface settings item, to let the pilot know when crossfill is turned off (disabled) or inoperative. Due to internal software configurations, changing aircraft inside MSFS will result in all GTN Xi units restarting. Note: TDS GTNXi Pro or Pro Upgrade are required for crossfill The GTNXi PC Trainer V20.42.2 or higher is required for crossfill. Please use the TDS GPS Manager V1.0.1.4 or higher to check/update the GTNXi PC Trainer 29 Interfacing with Hardware Sending events to simulate keys/knobs The TDS GTNXi supports accepting MSFS events(K events) in order to control the keys/knobs. The events used by the TDS GTNXi are regular MSFS events. Such events can be triggered via XML/JS code, Spad.neXt, MobiFlight. It is important to note that besides the actual event, a specified value must be sent. The value can be obtained from the table below, which describes the exact unit that the user wants to control. Four devices can be controlled by using this method: GTN750Xi Unit 1 GTN750Xi Unit 2 GTN650Xi Unit 1 GTN650Xi Unit 2 GPS_PAGE_KNOB_DEC GPS_PAGE_KNOB_INC Bottom Right Inner Knob Decrease and Increase where: 0 = GTN750Xi Unit 1 16 = GTN750Xi Unit 2 8 = GTN650Xi Unit 1 24 = GTN650Xi Unit 2 GPS_GROUP_KNOB_DEC GPS_GROUP_KNOB_INC Bottom Right Outer Knob Decrease and Increase where: 0 = GTN750Xi Unit 1 16 = GTN750Xi Unit 2 8 = GTN650Xi Unit 1 24 = GTN650Xi Unit 2 GPS_CURSOR_BUTTON Bottom Right Knob Push where: 4 = GTN750Xi Unit 1 UP 20 = GTN750Xi Unit 2 UP 12 = GTN650Xi Unit 1 UP 28 = GTN650Xi Unit 2 UP 2 = GTN750Xi Unit 1 DOWN 18 = GTN750Xi Unit 2 DOWN 10 = GTN650Xi Unit 1 DOWN 30 26 = GTN650Xi Unit 2 DOWN GPS_MENU_BUTTON Home Key where: 4 = GTN750Xi Unit 1 UP 20 = GTN750Xi Unit 2 UP 12 = GTN650Xi Unit 1 UP 28 = GTN650Xi Unit 2 UP 2 = GTN750Xi Unit 1 DOWN 18 = GTN750Xi Unit 2 DOWN 10 = GTN650Xi Unit 1 DOWN 26 = GTN650Xi Unit 2 DOWN GPS_DIRECTTO_BUTTON DTO Key where: 4 = GTN750Xi Unit 1 UP 20 = GTN750Xi Unit 2 UP 12 = GTN650Xi Unit 1 UP 28 = GTN650Xi Unit 2 UP 2 = GTN750Xi Unit 1 DOWN 18 = GTN750Xi Unit 2 DOWN 10 = GTN650Xi Unit 1 DOWN 26 = GTN650Xi Unit 2 DOWN GPS_BUTTON2 Top Left Knob, where: 2 = GTN750Xi Unit 1 Decrease 4 = GTN750Xi Unit 1 Increase 18 = GTN750Xi Unit 2 Decrease 20 = GTN750Xi Unit 2 Increase 10 = GTN650Xi Unit 1 Decrease 12 = GTN650Xi Unit 1 Increase 26 = GTN650Xi Unit 2 Decrease 28 = GTN650Xi Unit 2 Increase GPS_BUTTON1 Top Left Knob Push where: 4 = GTN750Xi Unit 1 UP 20 = GTN750Xi Unit 2 UP 12 = GTN650Xi Unit 1 UP 28 = GTN650Xi Unit 2 UP 2 = GTN750Xi Unit 1 DOWN 18 = GTN750Xi Unit 2 DOWN 10 = GTN650Xi Unit 1 DOWN 26 = GTN650Xi Unit 2 DOWN 31 Reading specific TDS GTNXi Data The TDS GTNXi provides L: variables to those interested in this data, to drive custom solutions/AirManager. TDSGTNXI_INSTALLED 1 means that the TDSGTNXI WASM Module is running TDSGTNXI_LateralValueActive If true, there is valid lateral navigation data TDSGTNXI_LateralValueMeters Lateral Deviation Value in Meters TDSGTNXI_LateralDeviationScaleNM Lateral Deviation Scale in Nautical Miles TDSGTNXI_APCourseToFly The deviation from the desired course to fly to actual track, in radians TDSGTNXI_ApproachType Oceanic = 0 Enroute = 1 Terminal = 2 Departure = 3 Missed Approach = 4 LNAV = 5 LNAV+V = 6 LNAV/VNAV = 7 LP = 8 LPV = 9 VISUAL = 10 TDSGTNXI_GlidePathValueActive If true, there is a valid vertical navigation data TDSGTNXI_GlidePathValueMeters Glide Path Vertical Deviation in Meters TDSGTNXI_GlidePathValueAngle Glide Path Angle, working range is between -1.0 to +1.0 TDSGTNXI_ToFromFlag 0 = TF Flag Inactive; 1 = TF Flag To; 2 = TF Flag From TDSGTNXI_NextWaypointDistanceNM Distance to Next Waypoint in Nautical Miles TDSGTNXI_NextWaypointDesiredTrackVal Desired Track Value to Next Waypoint in Degrees TDSGTNXI_NextWaypointBearingVal Bearing Value to Next Waypoint in Degrees TDSGTNXI_TotalDistanceNM Total Flight Plan Distance in Nautical Miles 32 TDSGTNXI_TotalETE Total Flight Plan ETE in seconds with the value being calculated past 30 knots ground speed, otherwise an invalid value of 359999.0 is displayed TDSGTNXI_TotalETA Total Flight Plan ETA in seconds based on Zulu Time with the value being calculated past 30 knots ground speed, otherwise an invalid value of 359999.0 is displayed TDSGTNXI_OBSModeActive If true, then OBS Mode is active inside the GTNXi TDSGTNXI_InstrumentPanelSelfTest If true, then Instrument Panel Self Test is active inside the GTNXi 33 Troubleshooting Uninstallation The TDS GTNXi can be easily and quickly uninstalled from the TDS GPS Manager. To uninstall the TDS GTNXi, open the TDS GPS Manager, login using your credentials, then access the Settings tab. You should see a screen as shown below, just select Flight Simulator and confirm the uninstall action. 34 Log Files The TDS GTNXi provides the ability to log information, warning and errors. The information is saved into log files, as described below: ● TDSGTNXiExeLog.txt for the main executable ● TDSGTNXi750Unit1Log.txt for the GTNXi 750 Unit 1 ● TDSGTNXi650Unit1Log.txt for the GTNXi 650 Unit 1 These Files are saved in the Windows Documents folder. They provide the information needed to troubleshoot most problems. 35 Antivirus infection alert During the installation or when running the TDS GTNXi, your antivirus may display an alert that a file may be infected with a virus. This is a false positive alert, all TDS GTNXi files are checked before being packaged and they do not contain any viruses. These alerts are false positives and TDS GTNXi all files quarantined/deleted by the antivirus should be restored. The files that may be quarantined/deleted by the antivirus program are: TDSGTNXiFlightSimEXE.exe TDSGTNServices.dll Both files are located here: C:\ProgramData\TDS\GTNXi\FlightSimEXE In case the antivirus has quarantined/deleted any one of the two files, please restore the file from the quarantine or reinstall the TDS GTNXi from the TDS GPS Manager. For all problems/questions regarding antivirus alerts, please post in the support forum. 36 FRAPS - Black Screen The TDS GTNXi is currently incompatible with FRAPS, the incompatibility will lead to black screens on both GTNXi displays. The solution is to close FRAPS when using the TDS GTNXi 37 AVG/Avast Antivirus Users - Black Screen In the very rare case when AVG/Avast Antivirus is installed and the customer experiences the GTNXi black screen, the solution is to add an antivirus exception for the TDS GTNXI Flight Sim installation folder and the PC Trainer executable folder or to temporarily disable real-time protection to confirm that this is the correct fix. Since this is a moderately complex process, we suggest contacting tech support for instructions. This problem has only been encountered with AVG/Avast Antivirus! 38 Performance Improvements Below is a two step guide on improving performance of the TDS GTNXi within MSFS. We recommend that all users apply these performance improvements for a much improved experience. Thanks to AirborneGeek for creating a YouTube video explaining all these performance steps in details: https://www.youtube.com/watch?v=naIefIcBvWw Important Note: Microsoft Flight Simulator 2024 requires a new process exclusion as described below! Step 1: Thanks to TDS GTNXi user and streamer Clumsy: https://www.twitch.tv/theclumsygeek And with the great assessment pointed by Ryan Butterworth We have been able to find a proper solution for customers experiencing performance degradation (FPS decrease) within MSFS2020/MSFS2024 and the TDS GTNXi. As this problem occurs only on some machines and we can't correlate the exact cause, we can't have a general fix, but we can point users who experience problems to this fix. To resolve the problem, you must add an exclusion to Windows Defender for these processes: For Microsoft Flight Simulator 2020: gtn_simulator.exe and FlightSimulator.exe For Microsoft Flight Simulator 2024: gtn_simulator.exe and FlightSimulator2024.exe As described here: https://support.microsoft.com/en-us/wind...01afe13b26 39 When clicking on Add Exclusion, select Process and then type the name and the extension, as shown above or in the screenshot below. Step 2: Enable a different drawing algorithm inside MSFS. With the Developer Mode active, access the Options Menu, then under the Experimental section, check the "Use NanoVG for XML gauges" This should decrease the load on the Main Thread and hopefully provide a performance increase using the TDS GTNXi as a VC Integrated option. 40 Tech Support To obtain tech support for the TDS GTNXi, please post your questions to the support forum: forum.tdssim.com You can also obtain support in the official TDS Sim Software GTNXi Discord channel: https://discord.gg/NupgPCUgsH To keep up to date with news, pictures and all other TDS SIm Software information, you can visit and Like our Facebook page: https://www.facebook.com/tdssimsoftware We stand by our products and we will treat all tech support questions with utmost importance.
