Yesterday, I finally had an opportunity to test my Contour GPS camera at the track. I mounted it to the steering stem of my GSXR. The image quality was pretty good, but the GPS function doesn't seem to work that well. I viewed the footage I took using Contour's own viewer. Contour's viewer has a function that identified my location, and plotted my position on the track, but it wasn't very accurate. Sometimes it plotted me driving around on the infield.
The speed function was not very impressive either. Specifically, while shifting at the redline in 1st, about 80mph on the GSXR, the GPS showed a speed of around 55 mph. At the end of the straight, with my speedo indicating 120+, the GPS was only registering around 80 mph. Also, the GPS speeds would continue to increase even though I was on the brakes hard and slowing for the next turn. The GPS lag on the short track was disappointing. In all, the refresh times for the GPS just seemed too slow.
