After the update of my 1030 from 7.50 to 8.00 something has changed on the saved track and on GPS tracking. With 8.00 happens that the track is much more inaccurate and sometimes the track is on the roads where I did not run and after 1/200meters bring back to the correct road. Sometimes if I run along a road with a bike path next to it, the track dances between the bike path, where I haven't raced, and the paved road where I ran. Until version 7.50 this did not happen and the tracks were much cleaner. I enclose tracks by comparing the versions to make them understand.
