Went snow shoeing in low temperatures today. while on the trail the fenix (connected to tempe) accurately displayed a temps down to -7F throughout my hike.. However when i uploaded the gpx/fit to garmin connect i see the graph records a temp of nearly 170F after the actual ambient fell to -3F (-19.9C).. Absurd!
see the Temp graph here: http://connect.garmin.com/activity/414841543
I looked at the GPX file itself and see the tags record the same thing (in Celsius). Below ive extracted the time and temp tags leading up to the weird spike in the fenix GPX log.
...begin hike, recorded temp slowly dropping to ambient since tempe was indoors prior to hike....

....about a 4 mile hike and 2 hrs pass at temps below -19.9c, and hop in the truck where temps begin to rise again...

The fenix was correctly displaying temps below -3F (-19.9C), and down to -7F (-21.7C) while recording the event on the trail. However, the actual logged data looks like at temps below -19.9C, the recorded value spikes oddly to 70C and remains pegged until the temp rises above the same threshold. Maybe this is one for the Fenix developers. anyone else seeing this?
