For reasons that I do not understand, battery manufacturers often recommend against charging Li Ion batteries in sub freezing temperatures. Do an internet search and you find that it is a hotly debated topic amongst battery experts.
I think some liquid crystal displays don't work as well in cold weather, but a GPS that is intended to be used outdoors should have a display that has a wide temperature rating.
