You'll have to be a little more specific about what you want from a "handheld GPS system" - I'm guessing that you want one with a built- in screen and you're concerned about uploading maps from your Mac, but I have a GPS-only unit which tells my Mac its position via Bluetooth. The only commercial software I know that takes advantage of this is Route 66 and that has a kinda clumsy interface, but there's an Open-Source interface to this, too (the GPS just appears as a serial port to the Mac, I think). The model I have is this one <http://www.pocketgpsworld.com/ SolarBTGPS.php> but I get the impression that all bluetooth GPS use the same chipset & are likely to work. Stroller.
