A PDA sounds like a reasonable solution. Do you know if a Palm will
work. I have gone through all of the Cambridge Aero pages on their

You can use "SoarPilot" with a Palm, it's free and available at:
http://www.soaringpilot.org/. I use it with a Cambridge 302A and a
Palm Tungsten T. I have not used it with a GPSNAV but according to the
Soar Pilot documents it will do what you want and more.
