General information
Operational readiness of the navigation system
The navigation system must determine the position of the vehicle before first use or whenever operational status is restored.
Therefore, you may have to drive for a while before precise route guidance is possible.
GPS reception
Correct functioning of the navigation system depends, amongst other things, on GPS reception. In certain situations, GPS reception may be impaired, there may be interference or there may be no reception at all, e.g. in tunnels or parking garages.
Entry restriction
On vehicles for certain countries, there is a restriction on entering data.
The restriction is active from a vehicle speed of over approximately 3 mph (5 km/h). As soon as speed falls below approximately 2 mph (3 km/h), the restriction becomes inactive.
When the restriction is active, certain entries cannot be made. This will be indicated by the fact that certain menu items are grayed out and cannot be selected.
The following functions, for example, may
therefore not be available while the vehicle is
in motion:
• entering the destination city and street
• entering a destination via the map
• entering points of interest in the vicinity of a city or via a name search
• editing entries
• using the number keypad for direct entry
