My 810 has started playing up. On a tour last week, it randomly switched itself off once a day on each day of a 7 day trip. Something that happened very rarely previously, is now occurring daily. There is no particular pattern to it. It could be after 10km, 50km or more.
Is this terminal? Is there anything I can do to sort it, e.g. reset it, or do I have to contact Garmin?
Thanks.
