I couldn't find this in the archives, so thought I would ask what the rest of the sailing community does for winter storage of the boat GPS. I know that the handheld comes home.Garmin says in their manual - "do not store in places where temperature extremes may occur". They then go on to say that - "temp. range is 5 deg. F to 158 deg. F".I have just removed my new GPSMAP 172 from its bulkhead mount on the boat, and have brought it home for the winter. Simple to do with an allen key, but was it necessary?You now see Garmin GPS units mounted on snowmobiles and RVs which are exposed to extremes in temp. GPS units are now found in many motor vehicles as well, and they sure as hell are exposed to extreme temperatures.Any thoughts?
