I bought an Edge 530 about 2 years ago and only just two days ago tried adding the cadence and speed sensors. They seemed to pair ok, but now when I start a new ride, the unit repeatedly autopauses - every few seconds of riding. It goes back and forth between being paused and recording many times, and many minutes of my ride aren't recorded as it is paused. Today, it recorded less than 30% of my ride. Any clues as to what is going on here? Ready to toss the speed and cadence sensors!
