A guy in Italy has written a free program for sailplanes, hang
glider and paraglider pilots that runs on any WinCE device with a touch screen.
This means that inexpensive 4.3 inch color screen car GPS such as Mio C320 can
now be a glide computer, FLARM alert (which also tells the vario reading of
nearby gliders), full color map display, on and on and on.

Watch the PowerPoint or the video on the home page for more features. These GPS
are available cheaply on eBay or direct from China:
