I don't know about adding airspace to a garmin unit, but I used Soar
Pilot last year with my treo 650 and a bluetooth GPS. The advantage of
such a system is that you can easily load turn points, and airspace.
Additionally it is a pretty full featured Soaring computer, and best
of all it's FREE! :-)

If you don't have a palm there's always XCsoar (freeware as well) for
the windows mobile family of PDAs
