The present invention provides a user experience greatly simplified from prior art GPS devices. The invention provides for storage of one or more locations, by simple user interactions tailored to the specific interaction environment. The invention also provides for determination of the current location of the user. The invention compares the current location to a selected stored location to determine a direction from the present location to the stored location. The invention also provides a determination of the present orientation of a display, relative to, as an example, magnetic north. The present orientation of the display can be combined with the determined direction to determine a configuration of the display that indicates a direction of travel toward the stored location. The invention can comprise a vehicle security system controller, and the operation of the invention integrated with the operation of the locking/unlocking of the vehicle.
