After the successful installation of FSUIPC you must register (paid) in order for this function to be present. If you go to the addon/FSUIPC menu (see image below). Then click the GPS out tab, check the enable box- then select your com port. We recommend using 9600 port speed and 2000 milliseconds. Check the AV400 box.
From the tools menu in the GPS, you MUST change the serial data interface mode to “Aviation In.” Without this setting, the GPS will not connect. This menu will be found in the Tools/Settings/Interface menu on your GPS depending on the model.
EVERY time you start the GPS for use with a simulator you must ALWAYS place the GPS in simulator mode for the PC to communicate with the handheld unit. Garmin does not allow this setting to be saved, so, unfortunately, you MUST, set the handheld in sim mode if the handheld is turned off. Sim mode disables any form of weather input if your device supports it.
