Does the 2535M Live have any hidden menus like the Garmins do? I remember my Garmin having two hidden menus. The first was accessed by tapping and holding the battery icon and the second was accessed by tapping and holding the center of the speedometer.
From the google translation, try holding the power button down far an extra amount of time.
