Hi Guys,

I’m using a Garmin Edge 520 Plus on my Giant Defy road bike. The bike has the Giant RideSense speed and cadence sensor that mounts on the left chainstay and communicates with the Garmin via ant+. Lately it’s been acting up, even after doing a reset on the unit. Today it told the Garmin that I was going 146 mph! Has anyone else had this problem and identified a solution?

Thanks,
Harry
