I am thinking of upgrading my PDA for my GNII.
The display should be readable in sun light. Presently I use a1550 as
primary with a 302 and the 39xx as a back up with a 302A. Maybe I
should get a CAI Nav display and one good PDA. Which one? Please make
recomendations.

Udo,

I have found the Ipaq 47xx is the best without the screen protector
for viewability and full backlight. I also updated the 4700 ROM to
Windows CE 6.0

Craggy Aero is also developing an instrument. Craggy Ultimate - Screen
Size 6.5 diagonal, sunlight viewable screen, with a backlight
controlled by potentiometer or photo sensor, VGA 680X420 twice the
screen resolution as the ClearNav.

Initial flight test were very favorable, no viewability problems with
direct sunlight.
