1. A vehicle trainable transmitter for actuating a garage door mechanism, said trainable transmitter comprising:
- means for receiving a first transmitted control signal having a radio frequency carrier signal from a remote control for a garage door mechanism, said first control signal having a carrier frequency and said receiving means outputting said first control signal;
circuit means coupled to said receiving means for inputting said first control signal, storing carrier frequency information and said circuit means for detecting control signal information and for storing detected control signal information;
means for generating and transmitting a second control signal from said frequency information and said control signal information stored in said circuit means, whereby said second control signal has the carrier frequency identified by said circuit means and the control signal information detected by said circuit means and said second control signal is selectively transmitted to actuate the garage door mechanism without the remote control; and
means for generating reference signals having different frequencies, said reference signal generating means controlled by a frequency control signal, wherein said reference signal generating means outputs reference signals at different frequencies which are input to said circuit means, the frequency of said output reference signal being varied until said circuit means detects that the frequency of said reference signal and the frequency of said first control signal from said remote control are substantially equal.

Abstract
A vehicle structural accessory includes one or more electronic accessories. One electrical accessory which may be provided is an electronically trainable transmitter which is trainable to generate a control signal which will actuate a garage door opening mechanism. Another electronic accessory which may be included is an electronic compass. Yet another device is an electronically adjustable mirror having parameters set for each driver of a vehicle. The electronically adjustable rearview mirror and the electronically trainable garage door opener may be advantageously provided with a keyless entry system.
