communication elements for providing a wireless communication link between the navigation unit and the remote display system.

2. The remote display unit of claim 1, wherein the display screen is flexible.

3. The remote display unit of claim 1, wherein the display processor, in response to the remote display system receiving location information from the navigation unit via the wireless communication link, causes the display screen to display a map and to indicate on the map the location of the navigation unit.

4. The remote display unit of claim 3, wherein the display processor updates the indication of the location of the navigation unit on the map in response to the remote display system receiving updated location information from the navigation unit.

5. The remote display unit of claim 3, wherein the location information includes a digital representation of the map to be displayed on the display screen.

6. The remote display unit of claim 3 further comprising, digital storage for storing digital representations of maps including a digital representation of the map displayed on the display screen.

7. The remote display unit of claim 6, wherein the position information includes longitude and latitude coordinates related to the location of the navigation unit, and the display processor, in response to receiving the longitude and latitude coordinates, selects from the digital storage a particular map that includes the longitude and latitude coordinates, as the map to be displayed by the display screen.

8. The remote display unit of claim 3 further comprising, a user interface for enabling the user to select a particular map to be the map displayed on the display screen.

9. The remote display unit of claim 3 further comprising, a user interface for enabling the user to change which map is the map displayed on the display screen.

10. The remote display unit of claim 3 further comprising, a user interface for enabling the user to select a portion of the map to be displayed in magnified form.

11. The remote display unit of claim 3 further comprising, a user interface for enabling the user to select a larger geographical area to be displayed on the map.

12. The remote display unit of claim 1, wherein the navigation unit is a GPS navigation unit.

13. The remote display unit of claim 1 further comprising, a user interface for effecting information displayed on the display screen.

14. The remote display unit of claim 1, wherein the user interface comprises a thin film keypad operably coupled to the flexible display screen.

15. The remote display unit of claim 2, wherein the flexible display screen comprises a light emitting diode (LED) matrix.

16. The remote display unit of claim 15, wherein the LED matrix is laminated.

17. The remote display unit of claim 1 further comprising a camera interface, wherein the display processor receives image data via the camera interface and provides the information via the wireless communication link to the navigation unit for display.

18. A navigation system comprising:

a navigation unit for determining a geographical position of the navigation unit;

a display unit located remotely from the navigation unit and including a display screen for displaying location information from the navigation unit to a user;

communication elements for providing a wireless communication link between the navigation unit and the remote display unit; and

a display processor for controlling the appearance of the display screen.

19. The navigation system of claim 18, wherein the display screen is a flexible display screen.

20. The navigation system of claim 18, wherein the display processor, in response to the remote display unit receiving location information from the navigation unit via the wireless communication link, causes the display screen to display a map and to indicate on the map the location of the navigation unit.

21. The navigation system of claim 20, wherein the display processor updates the indication of the location of the navigation unit on the map in response to the remote display unit receiving updated location information from the navigation unit.

22. The navigation system of claim 20, wherein the location information includes a digital representation of the map to be displayed by the display screen.

23. The navigation system of claim 20, wherein the remote display unit comprises digital storage for storing digital representations of maps including a digital representation of the map displayed on the display screen.

24. The navigation system of claim 23, wherein the position information includes longitude and latitude coordinates related to the location of the navigation unit, and the display processor, in response to receiving the longitude and latitude coordinates, selects from the digital storage a particular map that includes the longitude and latitude coordinates, as the map to be displayed on the display screen.

25. The navigation system of claim 20, wherein the remote display unit comprises, a user interface for enabling the user to select a particular map to be the map displayed on the display screen.

26. The navigation system of claim 20, wherein the remote display unit comprises, a user interface for enabling the user to change which map is the map displayed on the display screen.

27. The navigation system of claim 20, wherein the remote display unit comprises, a user interface for enabling the user to select a portion of the map to be displayed in magnified form.
