I have an Edge 820 which is paired to a Garmin speed/cadence sensor and tickr HRM. The unit has worked impeccably over the years until today.
While out for a ride it froze. The unit wouldn't respond to any inputs either on the screen or the physical buttons and all data on the screen remained static.
I had to do the hold-the-power-button-for-10-seconds restart to get it back to life. It froze briefly again shortly after that.
This has never happened before and none of the settings or hardware have been changed.
