Abstract
A garage door opener transmitter system includes a sensor for determining the relative direction of the garage door opener receiver. A transmitter then selectively transmits a signal in the direction of the receiver. In one embodiment, the direction of the receiver is determined based upon a compass and the direction of travel of the vehicle at the time the signal is transmitted.
