Yep; according to Garmin, this is a "design feature". There is a waterproof breathable membrane covering a small hole in the battery compartment. The main body of the receiver "breathes" through this hole, allowing the pressure in the unit to equalize (without water getting into the electronics). Air is drawn from (or expelled into) the battery compartment. The battery compartment itself is not air tight. The process of pressure equalization thus pulls (or pushes) small quantities of water into (or out of) the battery compartment. I would have preferred a design that has a waterproof battery compartment, with a waterproof breathable membrane in some other area (possibly protected by a small plastic grid). This would prevent the hassle of having to flush the battery compartment.
