Abstract: A method of operating a navigation apparatus is provided. A visual or audible navigation instruction, warning or alert is provided to a user via the apparatus. The navigation instruction, warning or alert is enhanced in a continuous or stepped manner as a given location to which the instruction, warning or alert relates is approached. The instruction may be an instruction regarding a manoeuvre to be performed at a junction in order to follow a calculated route. The instruction is visually enhanced by increasing its size as the current location of the apparatus becomes closer to the junction to more readily engage the attention of the user, and to facilitate interpretation of the instruction. Alternatively a warning regarding a safety camera may be increased in size as the camera is approached.
