I am also using Acceleration and my version is:
727 Captain (727-100 Base Pack) v2.7\n(c) 2015 Captain Sim www.captainsim.com
My switch shows High/Low ? In Windows10 (x64) Computer. Just open FSX\Accl. in my old windows 7 (x32) And the cap727. The Switch NAV/GPS displays there very transparent; Next to Master Test and Dimming Switch, which I don't have either in the windows 10 installation  :-/  ?

Taking into consideration that I had installer Activation Error and got dark gauges at one time, this could be the cause of this ? Hopefully I don't have to reinstall. Can you send me a new switch, or guide me how to edit it.
