Hi, I have an intermittent problem with my Garmin 255 not recording distance accurately. It seems to occur most when using the lap button it will record some laps fine and a random 1 or 2 laps as 0 miles. It is on the same stretch of road and from the map it looks like it has lost GPS. I tried switching off and re-connecting to the app, it worked for a couple of runs then the same problem happened. It has occasionally happened when just using it to record a whole run without using the lap button. It is a bit random, I always check it has GPS lock before I set off. Can anyone help, Garmin haven’t responded I sent an email 4 days ago.
