The firmware version 3.40 working fine.
I found another feature that is useful: Sight 'N Go. It must be called from the menu on the "Compass" page. Should not be started from the main menu!!!
A warning to those who use this firmware -> Because there is no barometric sensor "Descent Total", "Descent Average", "Descent Maximum", "Ascent Average", "Ascent Maximum", "Ascent Total" show incorrect values.
