The gps info wasn't of importance to me since I ride the same areas constantly. I wound up purchasing the Sigma Rox 9.0. Wireless cadence, speed, and heart rate. The unit will download all the information via the included usb cradle. The only thing I didn't care for was the cadence information wasn't part of the logs that could be downloaded. You can view the max and average cadence for a ride, but it isn't logged at 5 second intervals like the heart rate and speed.
