Most of these posts are old but is this still a common problem? I have had an 830 for about a month and yesterday the power sensor in my Garmin Rally pedals did not work at all and the HRM, also a GARMIN, gave up after about 5-10 minutes. I was unable to get them back without a full factory reset.
Not so impressive. Is an Element Bolt in my future after all?
Thanks,
