It is more a paste than a liquid. Of course everything freezes at
some temperature. Google "LCD storage temperature" will find you
typical ranges of -40 to +70 degrees C. Check your owner's manual.

My GPSmap 60CS specifies no storage range, but an operating range
of -15 to +70 C. I have used it as low as -25, but the screen has
almost no contrast and of course the batteries do not last long. I
keep it in an inside pocket and use an external antenna now.

Generally when you design "personal" electronics, you design for an
environment that can be tolerated by a person. Hence the LCD getting
finicky in cold weather.

I know a guy that liked to log his skiing trails with his garmin. He
ended up using your scheme (GPS in pocket and external antenna). That
unit failed in the cold, though it may not be due to cold. It was one
of the GPS12 variants.
