Hi,
I'm just letting you know of an issue that I have with the above 3 components.
Whenever I update the PMS GTN750 I am no longer able to use some of its functionality. Specifically, after upgrading when I use functions in the Utilities page of the 750, it throws out the flight plan and disconnects the ALT and NAV functions of the autopilot. I cannot re-add the flightplan, nor use the GPS function of the autopilot (obviously). I can, however use basic navaid VOR navigation and ALT hold functions. The workaround seems to be after I upgrade the 750 to uninstall FSUIPC7 (ver 7.4.11) through Windows uninstall APP feature and re-install the same version of FSUIPC7, after which the PMS GTN750 works as it should.
This is more of a 'for info' post. If you have any thoughts, that's fine, but I am ok using the workaround.
Cheers.
