I have a new 585c, just purchased about 3wks ago. Since installation I have kept it stored in a cloth bag (actually a crown royal bag) in one of my storage compartments. Used it in a tx last weekend and the dang screen was fogged up, moisture inside the screen!! Unit has not been exposed to rain or extreme changes in temp. My questions are, how to remove moisture from inside of the unit, possible cause?,reliability issues in the future? I know this is not one of HB's more expensive units, but come on this can't be a good thing. What would you do???????????
