The invention relates to a navigation device (200) comprising a display (240) for displaying a digital map to a user, a processor (210) configured to access digital map data and cause a digital map to be displayed to a user using the display, and a user interface operable by a user to enable the user to interact with the apparatus. The user interface is arranged to allow a user to select a continuous region present in the digital map by providing one or more indications on the digital map displayed to the user. The processor (210) is arranged to determine digital map data relating to the selected continuous region, and to carry out one or more mapping or navigation operations using the determined digital map data. The processor may calculate a route using a path selected on the map by a user.
