Set out on our tandem yesterday to do a 45 mile ride using a <history> track from our Garmin Edge 705. At about 16 miles, I took a wrong turn and the 705 started to recalculate, then told us to make aU-turn, which I knew was wrong, but later realized it was trying to take us home by a direct route. I tried to restart the process of using the <history>track to no avail. It couldn't find it even though it was listed in the<history> files.The air turned blue around us!! We were lost! Eventually we found our way home, but only did 25 miles and it wasn't so bad after all.
