  1. Open the Bridge software v2024.1.0, right click on the Cockpit Simulator logo in the upper left corner and then select About from the popup menu.
  2. What is listed in the “Detected simulator installations” and “Detected aircraft installations” sections?
  3. Try to edit the PMDG options ini file manually. First open the file “Prepar3D installation directory\PMDG\PMDG 737 NGXu\737NGXu_Options.ini” if you are flying PMDG 737NGXu or “Prepar3D installation directory\PMDG\PMDG 737 NGX\737NGX_Options.ini” if you are flying PMDG 737NGX and check if the following configuration properties are present:
    [SDK]
    EnableDataBroadcast=1
    EnableCDUBroadcast.0=1
    EnableCDUBroadcast.1=1
