Basic information about the
touch screen
The Navigation device is fitted with a
touch screen.
Operation
When you touch a button on the touch
screen, the button in question is briefly
shown outlined in red to confirm the
selection.
If you touch a button that is not active at
the moment, a short signal tone sounds.
Calibration
If the touch screen starts responding
imprecisely, calibration should be
undertaken.
The calibration function is started from
the
menu (see also page 133).
Basic information about the
menus
During operations, you are assisted by
various menus and entry windows.
