1. An apparatus, comprising:
- a portable device, having a position sensing part therein, which is actuated to determine a current position of the device;
a user interface, having a first control which is activated for storing a current position of the device as a stored location, and having a second control that provides a label for the stored location as stored in response to activating said first control, said label providing descriptive information about said stored location that was stored in response to activating said first control,and said portable device providing navigation information from said current position to said stored location responsive to selecting said stored location as a destination for navigation, where said navigation information includes directions to said stored location.

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.

6. A method, comprising:
-
in a portable device, using a position sensing part for detecting a current position of the portable device; determining if a current position storing memory in said portable device has a position stored therein; if said current position storing memory does not already have a position stored therein, then storing information indicative of the current position as a stored location in said current position storing memory; and in said portable device, detecting that position in said current position storing memory has been selected and automatically providing navigation information from a current position to said stored location. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A navigating system comprising:
-
a position determining system that determines a current position; a display part, that displays information indicative of said current position; a selection part, that allows entry of information indicative of a desired location; a navigation part that provides navigation information using at least said display part to display said navigation information, said navigation information guiding from said current position to said desired location; and
enabling storing information indicative of said current position determined by said position determining device, and subsequent retrieval of the stored position to allow navigating to the stored position using a single control for both said storing and said retrieval. - View Dependent Claims (14, 16)

15. A navigating system comprising:
-
a position determining system that determines a current position; a display part, that displays information indicative of said current position; a selection part, that allows entry of information indicative of a desired location; a navigation part that provides navigation information using at least said display part to display said navigation information, said navigation information guiding from said current position to said desired location; and
enabling storing information indicative of said current position determined by said position determining device, and subsequent retrieval of the stored position to allow navigating to the stored position, wherein said navigation part enables storing multiple stored locations, wherein said navigation part enables storing descriptive information associated with each of the multiple stored locations. - View Dependent Claims (17, 18)
