Hi.
3 months, I have had an issue with rebooting Enduro 3 during GPS activity.
And in happens in the Hike activity.
Mostly it happens when the datascreen is shown with 8 fields. But it can happen with less.
I tested different customs but really, it happens when the datafield displays ETA, ETA at Next, ETE, etc.
And it does not even depend on whether navigation started or not.
First, I thought it faced the January world GPS problem, and I performed procedures to update the GPS files. It did not help.
Finally, I did the total factory reset. And it has not helped me.
I opened some files from Garmin folders with debug data and found something like RTL Trap.
