Thermometer can't go below zero?
Mine registered -20 this morning. I almost took a pic because I think that's the lowest I've seen it. The home weather system said it was -22 so I'm sure there is room for error.
I can second that! It gets more and more inacurate as the temp drops but it's still within a couple of degree's. Lowest I've seen mine -35, I don't even try to drive it if it's colder than that!!!
We had some minus 10 and it showed that just fine. If you are at -1, and it is showing 0, I suspect that it is just error one way or the other. Temps can vary by a degree or two just based on the proximity to the ground also.
