When I first left the house it was about 30 to 40 degree out. My cateye worked for about 1.8 miles and then just showed under DST setting 0. 0 for speed and the distance never changed after 1.8. It didn't work the whole ride and once I got back in the house about 20 minutes later I spun the wheel and it worked. 30 to 40 shouldn't have froze it. Anyone have any ideas.
