Abstract
A navigation apparatus displays nodes of a navigation tree stored in a storage device in a manner that one selected node is displayed in an expanded display form and further nodes are displayed in a reduced display form on a display unit. In response to a selection of a subordinate node, the previously selected node is converted into the reduced display form and the newly selected node is converted into an expanded display form.
