Connecting to a Computer
You can connect the computer using a mini-USB cable. The GPS uses the same "mass storage" approach as the Oregon series, where the GPS shows up on your PC as a new drive letter, or on a Mac it shows on the desktop as a new drive. If you have a microSD card fitted, that will show up as a second drive.
