Garmin advertises the Dakota as waterproof. I tested its water resistance when I applied a protective film over the touch screen. The film adhesion requires wetting the touch screen and the moisture has not affected the GPS unit�s operations at all.
The touch screen replaces every button except for a pressure-sensitive on-off button that appears to be well-sealed. This eliminates a lot of avenues for water to enter the unit. The USB port is covered with a thick rubber flap and the battery compartment has deep grooves to accept a secure fitting cover. The unit appears durable and able to survive wet weather.
