I haven't done it yet, but this thread looks like it will be helpful...based on what they're saying, just download the 4gb US map file and load it on the device just like you would the garmin one. I've had other garmin's and they're easy to update, just connect them via usb to the computer and they'll show up as a directory and you just drag the files over. Not hard at all.
