I'm trying a new post since my latest reply on the matter has been removed from the moderators.
My 645 has been abandoned from Garmin. Seven months with no updates even though it's right below the top of the line of the forerunners.
I created an Hiking activity duplicating the walking one: nothing fancy here. I'm using only native data fields embedded on the watch, not even Connect IQ ones from Garmin, and yet it crashes.
When I'm super lucky it happens at the start (within a minute or so), so that nothing is really lost. Other times I'm not as lucky, especially when I was navigating a course and it leaves me with a black screen, refusing to wake up unless I trigger a soft reset. Which on turn greets me with zeroes aerobic and anaerobic efforts from the point it wakes up, after hours of hike.
And yes I tried everything:
- Navigating a course or just start a free hike
- Long courses or very short ones
- With zero or more external sensors attached
- Soft reset
- Hard reset
- Factory reset
- Watch replacement (the old one had faulty battery at the age of 11 months)
It still crashes and that to me is the proof that's just a bugged software. It doesn't crash 100% of the times, but it happens so often that I can't really trust my device, which is the point of a pricier Garmin watch instead of a generic cheapo.
Am I the only one which hikes with a 645? Any other feedback?
