[CA] [CA11] Night Screen for Axiom 9

[Glenn]

I have an Axiom 9, and in crossing Lake Michigan at night recently, I discovered that the display was too bright causing night blindness for me at the helm of my 36 foot sailboat. I turned the brightness down really low and it helped a bit, but reading things became much more difficult. Is there a night setting for the display which will help to alleviated night blindness? My old third party chartplotters automatically switched to a night screen after sun set which was very easy on the eyes and did not lead to night blindness caused by white light.
