Hi,

The S-NAV included task creation screens. When GPS units became inexpensive
the L-NAV became much more popular as tasks were done in the Garmin or
GPS-NAV. The S-NAV then slowly faded away. It does everything an L-NAV
does. It can connect to a GPS-NAV and send airspeed data through a GPS-NAV
to Glide Navigator II.

Hi,

Does anyone know the difference between an LNav and
and SNav? I know historically the LNav was positioned
as a 'budget' SNav, but looking at the manuals for
the current versions there doesn't seem to be any appreciable
difference between the two.

If anyone could outline the 'family tree' for the CAI
kit I would be most grateful.

Cheers,

Dan
