1. A remote keyless entry (RKE) transmitter operable to wirelessly communicate with an RKE system of a vehicle, the RKE transmitter comprising:
- logic operable to indicate a return trip having a plurality of return compass directions and return distances to a user, the return compass directions and return distances being sufficient to direct the user from a destination back to the vehicle;
wherein at least most of the return compass directions and return distances are determined as the user journeys from the vehicle to the destination.

14. A vehicle finder transmitter comprising:
-
logic operable to indicate a return trip as a plurality of journey segments sufficient to direct a user from a destination back to the vehicle, each journey segment defining one return compass direction and one return distance; an electronic compass element operable to facilitate determination of the return compass directions based on compass directions generated by the electronic compass element; an electronic signal strength element operable to facilitate determination of the return distances based on signal strengths measured between the transmitter and the vehicle; and wherein substantially all of the return compass directions and return distances are determined prior to the user reaching the destination. - View Dependent Claims (15, 16)

17. A computer-readable program operable to facilitate control of a remote keyless entry (RKE) transmitter operable with a RKE system of a vehicle to indicate a plurality of journey segments, the plurality of journey segments being sufficient to direct a user from a destination back to the vehicle after the user has previously traveled from the vehicle to the destination, each journey segment defining a corresponding compass direction and distance to be traveled by the user for that journey segment, the program comprising logic operable to:
determine substantially all of the compass directions and distances for substantially all of the journey segments while the user travels from the vehicle to the destination. - View Dependent Claims (18, 19, 20)
