Abstract
The invention relates to a navigation system, a terminal and a processing device for a navigation system, as well as a method for displaying navigation icons on display means of a terminal. In order to make efficient use of the storage space in the terminal and to allow flexible display of navigation icons, the storage of partial graphics in the terminal is proposed, with navigation icons being able to be composed from said partial graphics. To display a currently suitable navigation icon, the required partial graphics are then selected and composed to form the navigation icon. A processing device according to the invention is able to provide information which makes it possible for the terminal to determine the required partial graphics. The invention also relates to a module for a terminal or for a processing device comprising respective processing means.
