I have the Garmin Edge 500 bike computer. A weird thing happened last week.

I live in a town of 550+ residents, that has the moniker 'town within a forest'. So there are a lot of trees'. When I started my daily ride. I turned on my bike computer. Even with all the trees', it still started up completely. Then, Five minutes into the ride, I stopped on the side of a major road where there are no trees'. To check something with my camera. After I fixed the settings on my camera. I tried to get my bike computer going again. Even though there were no trees', it wouldn't grab the signal. I finally gave up n' came home.

But that hasn't happened since, and I have been on several rides since then.
