Abstract
The invention relates to a method and a device for a graphical user interface for a navigation system. The graphical user interface includes a display having several groups of symbols with each group arranged in a unique pre-determined direction relative to a start position. A user manipulatable directional input device permits a user to select any one of the groups with a single keystroke. Once a group has been selected, the directional input device permits a user to activate any one of the symbols within a group with a single keystroke. An activated symbol can be selected with one keystroke by the user. Selection of a symbol then re-activates the start position.
