Abstract
A device is disclosed for generating navigation instructions for display on a display device of a portable navigation device, comprising: means for accessing a repository storing digital map data pertaining to a navigable network along which the navigation device can travel, the digital map data including data pertaining to available lanes of the navigable network; means for generating, for display on the display device, a three-dimensional perspective view of a model representative of the map data as though from a camera positioned at an elevation and pitch angle behind a current position of the portable navigation device, that is updated to follow the device as it travels along a planned route, wherein the three-dimensional perspective view shows the available lanes of the navigable network, and wherein the planned route to be followed is shown in the view as a line, the line showing the route to be followed as passing along a determined current lane in which the device is travelling; and means for adapting the generated view, in response to detecting that the determined current lane in which the device is travelling differs from a lane or lanes associated with a manoeuvre to be …
