Color, grey-scale or black & white?


My Garmin 195 is easy to read in shadow or bright light without
backlighting during daylight. At night I have the backlight set to
remain on for 30 seconds after the light button is depressed.


I did notice that the new sunglasses I acquired last spring make the
screen too dark to view without removing the sunglasses.


What make/model and type of screen do you use and what affects its
"viewability"?


I have a Garmin 295, and a Fujitsu ST4121 Tablet (for XM weather).

The Garmin has a bright backlight, so it does fine in daylight.

The Fujitsu is a transflective display, which uses small holes in the
display to let sunlight through the display as a backlight. It is
also viewable in the daylight.

However - I wear a pair of Rayban polarized sunglasses, and they
definitely attenuate the ST4121 display. I usually end up taking off
the glasses if I am taking more than a quick look at the radar. The
Garmin does not seem to have this problem.

Nathan,

I suspect it depends on how you orient the display with respect to
your glasses...
