Offered here is ONE (1) piece new aftermarket data cable for Magellan 210/400/500/600/LE GPS. Made of super heavy duty cable and parts. Don't buy those cable whose socket/plug is thinly built. They look cute but they break and wear out easily. You don't want such experience when you are out in the woods or on the road!
Picture 1: what you see in picture 1 above is what you get.
The cable in this listing is compatible with:
Magellan eXplorist 210/400/500/600/LE
Use this cable to connect your notebook computer to your GPS. You can also use it for real-time map plotting.
Specifications:
tip to tip is 60 inches or 152 cm
This cable does provide power via the USB port. But if you don't want to draw power from your notebook computer and need an independent power source, purchase the power adapter separately...
Prolific makes the chip inside of your USB cable, and they do indeed make a Macintosh driver. If you wanted to be really awesome, you could also put their driver right on your driver CD: http://www.prolific.com.tw/support/files/%5CIO%20Cable%5CPL-2303%5CDrivers%20-%20Generic%5CMacOS%5CMacOS%2010.x%5Cmd_pl2303H_HX_X_dmg_v1.2.1r2.zip
(that link is the file for their driver). Their driver also includes a ReadMe file, for installing it, so you don't have to.
