Thanks but already seen it. The problem I have is that is showing no runs to download/calibrate. I've followed the guide to a T without success, I don't really expect it to be 100% accurate either but I would like to try and have it closer than the 50% that it is at the moment. VERY frustrating.
I bought one of these and ITS DRIVING ME NUTS!!! does anyone know how to calibrate it properly? I have tried 3 times on a track (different days/runs) to get a useful run. When I connect it to my PC it doesn't come up with any runs to calibrate. Its not even close - I ran 1200m today and it showed that I had run 630m!!
