Abstract
A navigation method and system having a unique key arrangement in which a minimum number of keys is incorporated for operations of a navigation system such as map scroll or map zoom in/out. Such key arrangement is configured by three buttons and is formed on a steering wheel of a vehicle or on a panel of a portable navigation system. The key arrangement performs at least an enter key function and an up/down key function. The key arrangement changes a current status of the navigation system to either a map scroll mode or a map zoom mode and scrolls a map image in a selected direction or sets a zoom scale of the map image.
