Lack return to the starting point

Some problems in the startup timer for the bike was not working. You only had to reset everything and everything is back in order. The tom tom sav has not found the solution !! It is I who has had to look around on the forums. As against the single button is very convenient but the display of the main data is too large compared to secondary data. Finally, it lacks the function back to the starting point in trail use. Too bad because a multifunction watch the price and with this option there would have made The WATCH.
