Recently my Garmin 500 stopped showing/monitoring my HR and instead started monitoring/ registering calories. The calorie displayed has shown zero since the first time I turned the unit on so this was unusual.
After about 30 minute the HR pops up showing my HR at 140 but doesn't change. When this occurs the calories display stops.
Has this been encountered by anyone before as it seems very odd.
The 500 has not encountered any unusual mishaps (drops, rain, etc).
Thanks
Don
