Patent abstract
A navigation device with improved zoom functions is disclosed. The navigation device is generally operable to display a map with varying magnifications and perspectives to enable a user to increase or decrease magnification and perspective without creating a substantial and immediate change in perspective. Such a configuration reduces user confusion due to the elimination of substantial changes in perspective during magnification and demagnification.
