A navigation device for navigating a vehicle to a point comprises a GPS receiver for receiving GPS signals, a processor connected with the receiver for processing the GPS signals, navigation data created by the processor, and a display page. The navigation data includes ground speed, altitude, vertical speed and rate of turn information, and the display page presents this information in individual graphic, circular displays representative of an aircraft instrument panel.

DETAILED DESCRIPTION A navigation device for navigating a vehicle to a waypoint broadly comprises a GPS receiver for receiving GPS signals, a memory, a processor connected with the receiver for processing the GPS signals, navigation data created by the processor, and a display page.
The navigation data includes ground speed, altitude, vertical speed and rate of turn information, and the display page presents this information in individual graphic, circular displays representative of an aircraft instrument panel.
The ground speed display and the rate of turn display are positioned along the left hand side of the display page with the ground speed display placed above the rate of turn display.
The altitude and rate of climb displays are positioned along the right hand side of the display.
The altitude display is positioned above the rate of climb display.
The navigation data also includes track information corresponding to movement of the device along a track.
The track information is presented in a graphic, circular display near the middle of the display page.
As a result, the display page resembles a standard aircraft instrument panel.
In an alternative form, the device is portable and may be placed in an air, water or land mode where the display page displays information directed toward aeronautical navigation, marine navigation or automotive navigation, respectively.
For example, in the air mode, a graphic, circular track display, as discussed above, is presented on the display page.
Cartographic data stored in the memory of the device may also be displayed on the display page in the form of a moving aeronautical-type map indicating progress toward the point.
The water mode includes the cartographic data displayed on the display page in the form of a nautical-type map, and a selected set of the navigation data presented on the display page in individual digital displays.
Finally, in the land mode, the navigation data includes directional information.
The directional information is presented on the display page in a written form providing a user with written directions in order to proceed along roadways to the point
