if you've got the old monochrome legend you need the "special" garmin cable to download through a serial port:o(

the newer garmins use a standard mini-usb cable as found on many digital cameras, mp3 players, card readers etc.

but as long as you have some kind of cable for it all you need is free software like easygps
