After a seemingly correct upgrade to 5.5.0 now my AP-74 lights all light up and can't be put out....was working fine before the upgrade...can't do much until Monday when support said to get in the airplane and call them...maybe they can help...they said it looks as if the AP-74 isn't 'talking' to the other Dynon units.
Did anyone else have this problem? :
