I have a Garmin Forerunner 35 that I use for cycling, running, walking. Recently it started doing something weird in activites where it stopped showing speed and the distance stopped. Occassionally this meant i was losing sections of an activity. Then it started to really struggle even picking up a signal before an activity. Even standing still for 10 mins outside in clear space. When it did connect it would track for 5 mins but nothig more. I've done hard and soft resets and while it can find the time, it wont record my location or movement. Software appears to be up to date on synch. I got the watch in Dec 2017, so maybe end of life, but HR function and time still work fine. Any ideas? Is this repairable?
