•
Visual warning: the type of the Alert Point, its distance and the related speed limit appear on
the Navigation view while you are approaching one of these locations.
For some of the Alert Points, either the enforced or expected speed limit is available. For these points,
the audio alert can be different if you are below or above the given speed limit.
•
Only when speeding: The audio alert is only played when you exceed the given speed limit.
•
When approaching: The audio alert is always played when approaching one of these Alert
Points. In order to draw your attention, the alert is different when you exceed the speed limit.
The warning for road safety cameras is usually disabled when you are in a country where
road safety camera warnings are prohibited. Make sure that using this feature is legal in the

country where you intend to operate. Use it on your own responsibility.

4.1.4 Route calculation and recalculation

A route is a sequence of route events, that is, maneuvers (for example, turns and traffic circles) to
reach the destination. The route contains one starting point and one or more destinations. The
starting point is the current (or last known) position by default. If you need to see a future route, the
starting point can be replaced with any other given point. See page 47.
Once the destination has been selected, Alpine Navigation System calculates the route based on your
preferences. These preferences are the route planning method, the vehicle type, and the road types
used or avoided when calculating the route. For detailed information on all the preferences, see Route
preferences settings, page 72.
Real-time traffic events are also taken into account, which sometimes greatly modify the route. See
page 65.
Alpine Navigation System automatically recalculates the route if you deviate from the proposed
itinerary.
If traffic services are enabled, Alpine Navigation System considers real-time dynamic traffic
information in route calculation and may also recalculate the route if the traffic situation changes
during navigation.
Intelligent data (captured historical speed information based on probe data) is used for optimal routing
depending on the day of the week and time of day. Route segments where traffic flow is typically slow
at the given time of day and day of the week are avoided if a suitable alternative can be found. W hen
calculating the optimal route, the data relevant for the time of the estimated arrival of the vehicle at the
given route point is taken into account. As a result, Alpine Navigation System may suggest a different
route during the weekday rush hours, especially in major cities with frequent traffic jams. See page
65.

4.1.5 Smart Zoom

Smart Zoom provides the following features:
•
While following a route: When approaching a turn, it zooms in and raises the view angle to let
you easily recognize your next maneuver. If the next turn is at a distance, it zooms out and
lowers the view angle to be flat so you can see the road in front of you.
•
While driving without a planned route: Smart Zoom zooms in if you drive slowly and zooms
out when you drive at a high speed.
