What was found
SETTING AN EVENT IN THE AUX PAGE FOR A FUTURE TIME CAUSES AUX EVENTS PAGE TO NO LONGER FUNCTION. SELECTING THIS PAGE CAUSES THE NAV6, GPS SATELLITE STATUS PAGE TO DISPLAY FOR 1 SECOND, THEN NAV2 PAGE(MAP) TO BE SELECTED. AS A SIDE EFFECT, THE FLIGHT TIMER IS RESET EVERY TIME THE AUX PAGE IS ATTEMPTED TO BE SELECTED. IT APPEARS THAT THE FIRMWARE BECOMES LOST, BUT RECOVERS.
