Just noticed the sticky thread above regarding the recommended process for GPS updates. Probably being paranoid but unfortunately when I got my watch, I remember only testing GPS for a minute or two to see how pace etc looked.
I have since used GPS a lot for running and cycling so I am wondering if you think a reset / re-calibrate is recommended for the best possible GPS results or will it be okay?
'After applying GPS software updates, for best results please allow the device to track GPS signals continuously for 15 minutes. This one-time process will allow the device to re-accumulate satellite information lost in the update process.'
