Switching the navigation device off
You can switch the navigation device off in two ways:

► Switching off: Press the (On/Off/Standby) button for at least 6
seconds.
In this state the device requires virtually no power. The following
message will appear the next time you switch the device on:
"Please note that the road traffic regulations are prior to the
instructions of the navigation system. Please do not operate the
device while driving."
As soon as you tap the OK

2.4 Navigation with GPS
GPS is based on a total of 24 satellites that circle the earth and, in
doing so, are constantly transmitting their position and time. The GPS
receiver receives this data and calculates its own geographical position
on the basis of the information transmitted by the various satellites.
For a sufficiently precise positioning it is necessary to obtain the data
from at least three satellites. With the data from 4 or more satellites the
altitude above sea level can also be ascertained. The determination has
an accuracy of about 3 yards.
Once the navigation device has determined your position, this position
can be used as a starting point for route calculation.
The map data on your navigation device includes the geographical
coordinates of all digitally recorded points of interest, streets and
places. This enables the device to calculate a route between a starting
point and a destination.
The calculation of the current position and its representation on the map
takes place once every second. So your current position is always
shown on the map.
