7.1 Starting the navigation application
You have switched on the navigation device. The START window is
open.
► Tap on Navigation.
The NAVIGATION window is opened. From here you can access all the
functions of the navigation application.
Returning to the Start window
You can go to the START window at any time by tapping on on the
(Start) button. This does not result in the current application
being closed.
Initialising the GPS receiver
Note: Good reception of GPS data requires an unobstructed path from
the GPS receiver to the satellites. Tunnels, narrow thoroughfares
between buildings and reflecting house fronts can restrict GPS
reception greatly or make it impossible. If the GPS receiver or the
navigation device is inside a vehicle, a metallised windscreen or a
windscreen heater can be the cause of poor GPS reception.
As soon as the navigation device has been switched on, initialisation of
the GPS receiver will begin.
The integrated GPS receiver is not initialised for the first time until the
navigation application is started for the first time. It can take up to
5 minutes to initialise the GPS receiver for the first time.
Each time you switch on the navigation device after this, GPS reception
will start within a short time.
If the navigation device has been switched off for more than a week, the
next initialisation can take up to 10 minutes.
Note: Directly after the GPS symbol indicates the GPS ready state, the
accuracy of the positioning may be reduced for a few minutes.
In the top right hand corner of the screen you will see the GPS symbol.
As soon as data from at least three satellites is received, the symbol will
change to (GPS ready).
Note: Initialisation takes the least time if you do not start driving until
the initialisation has finished.
For more details about the symbol refer to the chapter "GPS" on
page 23.
