Actually several of the LX series have a fluxgate compass input for
just this reason. I have no experience using them.

I have the compass on my LX 7000. It is a pain to get aligned and even
a small alignment error seems to affect the wind estimates, so I have
stuck with the circling mode. Without good heading data I think it is
impossible to estimate wind direction and speed in straight flight -
you can estimate headwind component based on true airspeed versus
ground speed if you have altitude (and temperature?) inputs, though I
am unsure as to which systems offer this.

I also run WinPilot and have found the two are generally pretty close
on winds - though not always, which make you wonder on those long
final glides...
