I recently got a Forerunner 230, but it looks like it might be broken beyond fixing (myself).. :(
The time/date keeps "jumping" every few seconds between the original time/date the watch has and the time/date it has gotten from the GPS fix.
1 moment: 03:39, saturday 7th
1 moment later: 15:49, wednesday 15th
Check the video for what it looks like:

When doing an activity in GPS mode (running or biking), the distance seems ok, but after syncing, it looks like this:

Also, during 2 short test running activities, the watch rebooted twice mid-run.. The Forerunner gets a GPS fix quickly when outside, full 'green' bars in seconds.
I've tried:
1. Restarting the watch
2. Factory reset
3. Updating to latest firmware
but nothing...
Any suggestions?
