5.1.3 Route calculation and recalculation
A route is a sequence of route events, that is, manoeuvres (for example, turns and roundabouts) 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 51.
Once the destination has been selected, Alpine navigation 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.
Alpine navigation automatically recalculates the route if you deviate from the proposed itinerary.
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 may suggest a different route during
the weekday rush hours, especially in major cities with frequent traffic jams. See page 1.
5.1.4 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 recognise 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.
5.1.5 Speed limit warning
Maps may contain information about the speed limits of the road segments. Alpine navigation is able to
warn you if you exceed the current limit. This information may not be available for your region, or may not
be fully correct for all roads on the map.
Speed warning can be fine-tuned in Warnings. See page 73.
You can also set the relative speed tolerance above which the application initiates the warning.
The following warning types are available:
• Audio warning: You receive a verbal warning when you exceed the speed limit with the given
percentage.
• Visual warning: The current speed limit is shown on the map when you exceed it (for example
).
You can also choose to see the speed limit sign on the map all the time.
