Abstract: The present disclosure relates to a technique for controlling the signalling of incoming telephone calls during a route guidance by means of a navigation device. A method aspect includes the steps of detecting an incoming telephone call, determining a distance to a forthcoming maneuver instruction or route reference point on a predetermined route in response to the detected telephone call, and delaying the incoming telephone call until a maneuver instruction has been output if the determined distance to the forthcoming maneuver instruction or route reference point falls short of a predetermined threshold value.

Abstract: A technique for determining location data from a database is presented. A method implementation of that technique comprises receiving a first user input defining an extension of a search corridor relative to a map visualized on a display unit. The search corridor extends from a first map area to a second map area spaced apart from the first map area. In response to a second user input defining one or more characters, location data are determined of at least one location associated with the one or more characters and lying within the search corridor. The technique may be used for searching for an intermediate or target location in connection with calculating a route.

Abstract: A technique for manipulating precalculated routes on a screen is described. One aspect of the method comprises the steps of detecting a selected screen position (P) and a time period (t) of a selection operation at the screen position (P), modifying weights of the road segments in dependence on the detected screen position (P) and the time period (t), and calculating a route, manipulated in relation to the precalculated route, on the basis of the modified weights.

Abstract: The present disclosure relates to a technique for controlling the signalling of incoming telephone calls during a route guidance by means of a navigation device. A method aspect includes the steps of detecting an incoming telephone call, determining a distance to a forthcoming manoeuvre instruction or route reference point on a predetermined route in response to the detected telephone call, and delaying the incoming telephone call until a manoeuvre instruction has been output if the determined distance to the forthcoming manoeuvre instruction or route reference point falls short of a predetermined threshold value.
