I read that most of the Garmin avionics backlight can be setup with a lighting bus treshold voltage. When the input voltage at the lighting bus is below a certain level i.e. 1.5V the LRU will automatically switch to AutoBrightness using the integrated photocell.
Is this valid for the GDU460 as well? I found this 'Off Threshold' for the GDU37X only..
I would like to control the avionics backlight via the GAD27+potentiometer.. I just couldn't find this option for the GDU46X in the manual.
