Bill,

Does any one have a AirMap® 600C and have done this? Is there a 3rd
party program that can do this?


I think MapCreate can do this, but I am not sure.

However, see
http://www.aeroversand.eu/gpsempfaen.../waypoint.html for
alternative methods. One of the coolest options (to me) is to load
trails into Google Earth. You'll need GPS Babel and GPS Visualizer.

I hate to disappoint you, though: The Airmaps do not store altitude in
their trail data. No GPS unit I know of stores speed, they only do
position (and altitude, if not from Lowrance).
