The GPS 18 has no display and can only be used with some laptop software (such as MapSource WorldMap).
You may wish to buy a cheap Garmin mapping GPS that can also be used on its own if the laptop fails. The Garmin eTrek Legend is one such unit.
You can also connect the eTrek Legend to your laptop for the bigger screen display.
