Abstract
A locator device includes a pocket-sized casing that contains a keyless remote entry circuit for remotely operating a vehicle security system. A GPS receiver circuit is located in the casing and automatically identifies a vehicle waypoint whenever the vehicle is turned off. The locator device then determines from any current location and with a single button press the direction and/or distance back to the vehicle waypoint. Many other novel applications are also performed by the locator device.
