storage means for storing location information for a designated geographic location, the designated geographic location not dependent upon the present location;

processing means for receiving information regarding the present location and the location of the designated geographic location in order to determine directional information, the directional information relating the present location to the location of the designated geographic location;

display means for displaying the directional information; and

control means for monitoring/controlling the function of at least one of the present location determining means, storage means, processing means, and display means.

2. The apparatus of claim 1, wherein the present location determining means utilizes a user input to determine the present location.

3. The apparatus of claim 1, wherein the present location determining means utilizes information received from a base station to determine present location.

4. The apparatus of claim 1, the storage means containing location information corresponding to place names and wherein the control means retrieves place name location information from the storage means and provides the place name location information to the processing means.

5. The apparatus of claim 4, wherein the place names comprise at least one of names of major cities, names of major countries, and names of predetermined destinations throughout the world.

6. The apparatus of claim 4, wherein the location information comprises latitude/longitude information.

7. The apparatus of claim 4, wherein the location information comprises directional information.

8. The apparatus of claim 2, wherein the user input comprises one of a place name corresponding to a predetermined location stored in the storage means, points on an electronic map displayed by the display means, latitude information corresponding to the present location, and longitude information corresponding to the present location.

9. The apparatus of claim 8, wherein the control means retrieves location information corresponding to the user input from the storage means and provides the information to the processing means.

10. The apparatus of claim 9, wherein the user input comprises at least one of latitude and longitude information.

11. The apparatus of claim 8, wherein the control means provides the user input to the processing means as the present location.

12. The apparatus of claim 8, the user input comprising a place name and wherein the control means retrieves location information corresponding to the place name from the storage means and provides the information to the processing means.

13. The apparatus of claim 1 further comprising a compass means for translating the present location into compass point user information.

14. The apparatus of claim 13, wherein the compass means is an electronic compass fixed directly to the apparatus and the control means retrieves compass point user information from the compass.

15. The apparatus of claim 14, wherein the compass means is a terrestrial magnetism unit.

16. The apparatus of claim 13, wherein the compass means is a mechanical compass.

17. The apparatus of claim 16, wherein the compass is fixed directly to the apparatus.

18. The apparatus of claim 1, wherein the display means displays the directional information as a fixed direction.

19. The apparatus of claim 1, wherein the display means displays the directional information as compass points.

20. The apparatus of claim 1, wherein the designated geographic location is Mecca.

21. A mobile communication device for representing directional information to a user, comprising:

a present location determining unit for determining present location in response to at least one of location information from a base station and a user input;

memory containing location information corresponding to a designated geographic location, the designated geographic location not dependent upon the present location;

a compass;

a processor for receiving information regarding the present location and the location of the designated geographic location in order to determine directional information, the directional information relating the present location to the location of the designated geographic location;

a display for displaying the directional information as either a fixed direction or compass points; and

a controller for monitoring/controlling the function of at least one of the data entry unit, memory, processor, and display.

22. The device of claim 21, wherein the controller retrieves latitude/longitude information from the memory and provides the latitude/longitude information to the processor as the present location of the user.

23. The device of claim 21, wherein present location is determined by the location of the device and the controller receives location information corresponding to the present location of the device from a base station and provides the received location information to the processor.

24. The device of claim 21, wherein present location is determined by a user input.

25. The device of claim 24, wherein the user input comprises latitude/longitude information and the controller provides the user input to the processor as the present location.

26. The device of claim 24, wherein the user input comprises a place name and the controller retrieves location information corresponding to the place name from the memory and provides the retrieved location information to the processor.

27. The device of claim 24, wherein the user input comprises a point on an electronic map displayed by the display and the controller retrieves location information corresponding to the user input from the memory and provides the retrieved location information to the processor.

28. The device of claim 21, wherein the compass is a terrestrial magnetism unit fixed directly to the apparatus and the controller retrieves compass point user information from the compass.

29. The device of claim 21, wherein the compass is a mechanical compass.

30. The device of claim 29, wherein the compass is fixed directly to the device.

31. The device of claim 21, wherein the designated geographic location is Mecca.

32. A method of providing directional information related to a designated geographic location, comprising:

providing a mobile communication device having present location determining means, storage means, processing means, display means, and control means;

determining present location by receiving at least one of location information from a base station and a user input;

comparing present location to location information corresponding to the designated geographic location in order to generate directional information, the directional information relating the present location to the location of the designated geographic location, the designated geographic location not dependent upon the present location; and

displaying the directional information.

33. The method of claim 32, further comprising:

determining that present location is determined by the location of the device;

communicating with a base station to receive location information corresponding to the location of the device; and

transferring the received location information to the processing means as the present location of the user.

34. The method of claim 32, further comprising:

determining that present location of the user is determined by reference to an electronic map;

displaying an electronic map;

receiving user input comprising information related to the electronic map;
