I got my GPS mirror not too long ago and it worked great except last week and this week.
It is very cold here in Montreal, Canada and temp is around -25C with wind.
The mirror gets stuck sometimes on the wrong speed or is way off and speed keeps going very high up then down, even if i go at constant speed.
Today, i was rolling at 50 km/hr and it was telling me i am at 84 km/hr?
So does the cold weather affect the mirror like this? is this normal or is my unit bad?
