My Garmin has suddenly stopped being useful. When I start an activity, the timer runs but the distance travelled does not increase. I have tried doing a factory reset and the same result. When I try and sync it with my computer (macbook pro) it says there are updates to be installed, but then says "There was an error synching with Garmin Connect".
Any ideas why it isn't synching nor is the distance updating?
Garmin Edge 510
Thanks
