Weird S/M 2 quirk?

It is odd. I will start the car up and head out to work in the morning, I turn the scanmaster to mph. It reads below my analog speedo by about 5-7 mph. Maybe about 10 minutes later it is reading correctly. Is this a normal thing for s/m to do?
Reason I ask, is because I wonder if the cold nights are affecting it being out there. This is upstate NY after all, and it gets into the high teens now at night. I have permanently put it in, but if the electronics are that sensitive, maybe I should figure out a temporary mount system for it. Anyone with a thought on this?
