The GNS V2 inherits two new features first introduced in our FltSim version:

Link Simulator GPS Waypoints: continuously updates the stock GPS/FMS route with the next waypoints (requires Master Device). This feature is designed to displaying GNS route on EFIS displays. XPlane limitations: user waypoint ident or waypoint not in the XP database display as encoded lat_lon format.

Auto-Save Active Route: save the active route to "X-Plane\Output\FMS plans\Reality XP GNS1 Route.fms" (and GNS2 for unit 2). This is a v11 or v3 compliant fms file (depending on your XP version) with the entire active route (not just the next waypoints). The device saves the route whenever it changes so that the file contains the latest used.

This update also fixes the VR window handling issues encountered with our first VR version (2.5.1).


  • New: Supports X-Plane 11.20 VR mode.
  • New: Added support to fail RAIM Check via datarefs.
  • New: Added discrete inputs datarefs.
  • New: Additional commands (discrete inputs like in GTN XPlane): 'CDI_SOURCE', 'OBS_MODE' and 'TAWS_INHIBIT'.
  • Fixed: GNS overrides A/P and HSI when loaded with some aircraft (no reload needed).
  • Enhanced: TAWS auto-detected limits are properly saved in the ini file.
  • Enhanced: User's Manual corrections and additional information.
  • Enhanced: Further stability and performance enhancements.

X-Plane 11.20 VR:

XPlane has known limitations which you should know: resizing the window with 2 green bars changes the definition, not the size (makes the graphics pixelated), therefore, resize the GNS window 1 green bar at a time instead. Also, XPlane SDK permits restoring the window size only and not its position.

A/P and HSI override:

This should fix the issue with some aircraft (Carenado, etc...) where the GNS was not able to connect to the A/P and the HSI when initially loaded, and for which the interim fix was to unselect then reselect the GNS from the menu.


  • New: LinkObs connects GPS to OBS source, either HSI (with LinkHsi) or VOR (AutoNavSource).
  • New: Autopilot coupling and tracking compatible with host simulator simulation rate (up to 128x).


  • New: Popup Windows compatible with the latest XP11.20+ VR.
  • New: SHIFT+RIGHT Click the GPS top edge opens the GUI Settings (like FltSim version).
  • New: SHIFT+LEFT Click the GPS top edge resizes the popup window (like FltSim version).
  • New: Added 'Master Device' setting to the GUI Settings (like FltSim version).
  • New: GNS Hardware Driver compatible with 64bits simulators*
  • Fixed: GPS Master Device state not saved to the settings file (take 2).
  • Enhanced: The plugin log file name is now "Documents\rxpGNS2.xpl.log" for consistency.
  • Enhanced: User's Manual renamed to: "Reality XP GNS V2 User's Manual (XPlane).pdf".
  • Enhanced: Installer cleans up older manual and shortcuts left from previous installations.
  • Enhanced: User's Manual corrections and additional information.
  • Enhanced: Further stability and performance enhancements.

* The installer includes the latest PFC DLL 32/64bits but the feature requires a separate GNS Hardware Driver product license to function.


With the previous versions, the option used to only connect the HSI OBS to the GPS. 

New in v2.4, when using the LinkObs option, the OBS source is either the HSI OBS when the GPS device is connected to the HSI (LinkHsi option), or the VOR1/2  OBS when the GPS device is connected to the VOR (in this case VOR1 or VOR2 depends on the AutoNavSource setting).
