Hello,
Just bought this 645M new a month or so ago. Working great. Noticed today that as of like 9pm Thursday night, my HR stopped working. I have tried every reset/turning off/toggle I could find in my google search. NOTHING worked. (Yes, I have emailed garmin support, but hoping to get some ideas from you guys first).
When I hard reset, the green lights for the hr sensor come on, but then after a time they turn off. At first I thought it was just my HR data not working, but steps as well are not working! I am able to see my calories burned. I am not sure what caused this. Anyone have any ideas to get my HR+steps working again?
Eric
