1. A portable transceiver for use in communications with an automobile, comprising:
- a transmitter that transmits signals to activate a remote keyless entry (RKE) feature of the automobile;
a locating device that tracks a distance and direction of a plurality of traversed paths of the transceiver relative to a waypoint;
an altimeter that measures elevation;
a processor that processes the plurality of traversed paths, and reconstructs a return path back to the waypoint, wherein the return path corresponds to the plurality of traversed paths, and in response to an activation of the RKE feature, the locating device determines the waypoint corresponding substantially to that of the automobile; and
a display that simultaneously displays a pointer indicating a direction from a current one of the plurality of traversed paths to a next one of the plurality of traversed paths, a waypoint indicator indicating a distance from the current one of the plurality of traversed paths to the next one of the plurality of traversed paths, and a set of arrows indicating an elevation direction from the current one of the plurality of traversed paths to the next one of the plurality of traversed paths,wherein the transmitter, the locating device, the altimeter, the processor and the display are housed in a pocket sized housing.

13. A method of guiding a user to a vehicle, comprising:
-
marking a waypoint corresponding to the user'"'"'s location upon arming of a security feature of the vehicle; tracking a distance and direction of a plurality of traversed paths of the user relative to the waypoint; reconstructing a return path back to the waypoint, wherein the return path corresponds to the plurality of traversed paths; and displaying, simultaneously, a pointer indicating a direction from a current one of the plurality of traversed paths to a next one of the plurality of traversed paths, a waypoint indicator indicating a distance from the current one of the plurality of traversed paths to the next one of the plurality of traversed paths, and a set of arrows indicating an elevation direction from the current one of the plurality of traversed paths to the next one of the plurality of traversed paths. - View Dependent Claims (14, 15, 16)

17. A portable transceiver for use in communications with an automobile, comprising:
-
a transmitter that transmits signals to activate a remote keyless entry (RKE) feature of the automobile; a locating device that tracks a distance and direction of a plurality of traversed paths of the transceiver relative to a waypoint, wherein the transmitter and the locating device are housed in a pocket sized housing; and a processor that processes the plurality of traversed paths, and reconstructs a return path back to the waypoint, wherein the return path corresponds to the plurality of traversed paths, and in response to an activation of the RKE feature, the locating device determines the waypoint corresponding substantially to that of the automobile and initiates a tracking procedure that measures a distance that the transceiver is moved away from the waypoint in three dimensions. - View Dependent Claims (18)
