Oops, one more remark !

Direct sunlight IS beatable.
My current Car System ( Clarion ) is well readable under *extreme* sunlight,
because then the display looks inverted ->
The numbers/letters then appear darker then the background.
But of course the backdrop is -> the display is not readable under medium light conditions, because then background and numbers/letters are the same brightness.

But -> a nice try from clarion ( if this was intended ).
