A navigation system for providing navigation information to a user responsive to user commands includes (1) a user device for issuing user commands and displaying a user interface to the user and (2) a navigation device for connecting to the user device and receiving user commands from the user device and transmitting navigation information to the user device. The information received from the user device includes updated map information, traffic information, news information, weather information, event-related information, business-related information, and user-specified information. The navigation device performs route following based on commands received from the user device and transmits routing instructions to the user device. The navigation device and user device are separately operable by a user.

Intelligent modular navigation information capability

A technique for displaying topographical data, for example, on a screen of a portable hand-held device includes: optionally receiving GPS (Global Positioning System) signals and generating a digital output indicative of a position location of the display device in response to the received GPS signals or inputting location data manually to produce an image on a display screen of the device in response to the digital output; and storing true digital elevation data as compressed cells and decompressing on-the-fly only data needed to provide elevation data for an image area displayed on the display screen.
