Marc,
You said the magic words.  You have a wing and a cabin to give you enough shade to see the unit.  The Legacy is a low wing open canopy.  The unit is unusable in that set up.  It does work well at noght and under cloudy conditions.  I hope they fix the system so open canopy planes can make use of this unit.

I fly with a Sandel HSI in a Cessna 210.  I have no problem reading the
display at night or when the panel is not in direct sunlight.  It is
less easy to read in direct sunlight (especially when compared to a
conventional HSI), but it is still readable without straining my eyes.
It is almost impossible to read from the co-pilot's side during the day
(not in direct sunlight).
