I have a question about the better computers out there. I have a cheap computer that the screen turns completely black after 10 minutes of riding in our 100+ degree days, meaning I can't read anything. It still records all the information, but I can't see my speed, distance, what time it is... anything. When I get to where I'm going I have to throw it in a cup of ice water for a few minutes to see anything. Is this a problem you guys have on your better computers?
