Abstract

A privacy enhancement device for electronic device such as a cellular telephone. The privacy enhancement device may include a jammer which may produces false information, e.g. false information indicative of pseudo ranges. In addition, the navigation information used on the position detecting device may be locally stored versions of dynamically changing information. The navigation operation may be carried out using a Web service.

Claims

1. A method, comprising:

operating a navigation system which enables determining a current position and a desired location, and providing navigation information that guides from the current position to the desired location;

carrying out a web browsing operation using said client, which web browsing operation allows determining a desired item or location from a remotely accessible database that is accessed using the web browser, downloading information about the desired item or location, and providing said information to said navigation system which provides said navigation information to guide to said desired item or location.

2. A method as in claim 1, further comprising storing the downloaded information as a bookmark, which can be retrieved and used to set the desired location when retrieved and wherein said and wherein said providing navigation information comprises providing navigation information to the retrieved information from the bookmark.

3. A method as in claim 1, wherein said information is an address.

5. A method, as in claim 1, wherein said client is a cellular phone.

6. A method as in claim 1, wherein said database includes messages, and said item or location is a destination noted in a message.

7. A method as in claim 1, wherein said navigation system sends said current position and said desired location to a server, and receives navigation information from said server, responsive to said sending.

4. A method as in claim one, wherein said description is a description of a restaurant or a hotel.

8. A method, comprising:

operating a navigation system which enables determining a current position and a desired location, and providing navigation information that guides from the current position to the desired location;

accessing a remotely accessible database over a network;

selecting a desired entry from said database over the network;

automatically downloading information indicative of the selected entry to said navigation system; and

setting said information as said desired location in said navigation system, and providing navigation information that guides from the current position to the desired location comprising the information from the desired entry from the database.

9. A method as in claim 8, wherein said entry is a restaurant or a hotel.

10. A method as in claim 8, wherein said entry represents a destination that is set forth in a message.

11. A method as in claim 8, wherein said information represents a physical address in a form that can be understood by a positioning device.

12. A method as in claim 8, wherein said form represents coordinates in a form that can be understood by said positioning device.

13. A method as in claim 8, wherein said operating, selecting and downloading is carried out in a cellular telephone.

14. A system as in claim 13, wherein said navigation part sends said current position and said desired location to a server, and receives navigation information from said server, responsive to said sending.

15. A navigating system, comprising:

a navigation part which operates to determine a current position and allows entry of information about a desired location, and provide navigation information that guides from the current position to the desired location;

a web browsing part, associated, with said navigation part, said web browsing part accessing a remotely accessible database over a network, and allowing selecting a desired entry from said database over the network and automatically downloading information indicative of the selected entry to said navigation part; and

said navigation part operating to set said information as said desired location in said navigation part, and provide navigation information that guides from the current position to the desired location comprising the information from the desired entry from the database.

16. A system in claim 15, wherein said navigation part and web browsing part are parts of a cellular telephone.

17. A system as in claim 15, wherein said navigation part determines its position using both GPS and at least one non-GPS item of information.

18. A system as in claim 15, wherein said navigation part sends said current position and said desired location to a server, and receives navigation information from said server, responsive to said sending.
