
Audio warning: beeps are played (if the voice guidance language that you selected is a natural
voice) or the type of the alert can be announced (TTS voice) while you are approaching one of
these points, and an extra alert warns you if you exceed the given speed limit while approaching.

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 70.
Real-time traffic events are also taken into account, which sometimes greatly modify the route. See page
62.
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. When
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 62.
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.
