1. An apparatus for displaying route data received from one or more navigation devices, comprising:

  • a display device to display graphical information including one or more trajectories, each trajectory indicating a route travelled by said one or more navigation devices;

    a processor arranged to control the display device to display the graphical information;

    a store for colour mapping information, said colour mapping information being representative of a relationship between orientation-related information of a trajectory and colour, the orientation information comprising an angle and/or gradient; and

    a trajectory-colour module to determine orientation-related information of a trajectory and related colour according to the colour mapping information, said processor being responsive to the trajectory-colour module to control the display device to display a graphical element at least partly in the determined colour, wherein the determined colour provides an indication of a direction of movement or heading of a navigation device on the relevant part of said trajectory.
