Thanks for your reply. Are you able to a look at http://connect.garmin.com/modern/activity/419491985? This is the first activity prior to starting to use my Edge 500. For me this is showing a map of Overland Park, somewhere in the USA I guess! It should be near Ledbury in the UK. I tried re-importing the GPX for this activity after exporting it from Strava. It got the map right, but the distance was showing as 0.2 miles!
