Hello there. Since I'm freezing my n*ts off here in Finland - I have a question; How cold can it be whilst okay to use your navigator 24/7 without removing it from your car? I mean I know the temperature range told in user manual but this is the first winter I've been using mine all winter now and couple of days ago it was at least -15°C during daytime and probably more at night.
However, I do use a pre-heater that warms not only the engine but also inside of the car. So when I'll start the car/navigator the inside temperature is a lot warmer than outside temp. At night though temp might be anything between 0°C to -15-25°C.
