Hi,
I have had different models of Garmin and used to be a brand fan. Not anymore. Garmin Forerunner 645 Music has been a pain.
Besides tracking incorrectly my races (my last marathon had 1km splits of 0.5 km; total marathon distance of 44.2km) and paces, it now keeps turning on by itself, even when stored, and disconnecting from headphones. I did a hard reset, but nothing seems to work.
Any advice is greatly appreciated. Thank you!
