I have recently had lots of problems with my 405cx. It seems it doesn't like sweating on it. At the same time The dashboard on Garmin connect has deleted or lost all my runs from the last couple of years. I did a hard reset on the watch but have not altered anything on the dashboard. I just completed a half marathon today and the run appeared to download to Garmin no bother but when I went to the dashboard there is no sign of it. Help?
p.s. I have been reading a lot recently about the poor lifespan/quality of Garmin products, hope its not true.
