I have owned a Garmin Forerunner 620 previously and in the 4 years I owned it, I had it reset spontaneously during my run maybe 5 times the entire time. But in the month I have owned my 645, it has reset twice already. Yes it saves the distance, and the run is saved but things like Aerobic Training effect reset to 0 which is frustrating. What can I do to stop this?
I had noticed that it was happening during live segments while listening to music, and tracking my run- so I have now removed Live Segments but not sure if there is more I should do.
