A method and device for displaying animated navigation information has a processor, a memory, a display, and an input, housed in a portable, handheld housing. In various embodiments of the present invention, a plurality of frames are stored in memory, wherein each frame includes data indicative of a still-shot of a portion of an animated sequence represented by the total plurality of frames. The processor retrieves the frames in sequence for display on the display, such that successively displaying each of the frames on the display presents a visualization on the display of animated movement. In one aspect of the invention, animation is provided upon power up of the unit to provide the user with an indication of the nature of use and features of the unit. In another aspect of the invention, animation is provided to provide an indication to the user of satellite signal acquisition for use in navigation purposes. In another aspect of the invention, a graphical menu driven system is provided, such that upon entry of menu selection, a graphical representation indicative of the selection made appears on the display screen. In accordance with another aspect, as the user of the navigation unit moves with the navigation unit on his or her person, the navigation unit tracks the movement and provides an animated, graphical representation indicative of movement of the user.
