Remote control interface for replacement vehicle stereos
An interface circuit for interconnecting the fixed controls of a vehicle to a replacement stereo. The interface circuit is capable of receiving control signals from fixed controls, such as steering wheel controls, backseat controls, handlebar controls, and the like, and then transmitting corresponding control signals to a replacement stereo. In one embodiment, the output signals from the interface circuit are comprised of wireless signals, such as IR signals. In another embodiment, the interface device is programmable such that the interface device can be programmed to emit signals corresponding to the same signals that would be emitted from a handheld remote control sold in conjunction with an after-market stereo receiver.
1. A stereo control interface device adapted to be installed in a vehicle as an aftermarket product, the device comprising:
a receiver adapted to receive at least one input signal, the at least one input signal comprising a control signal in a first format configured to control an originally installed stereo receiver responsive to signals in the first format, at least one stereo control originally mounted in the vehicle at a location remote to the original stereo receiver; and
a transmitter adapted to produce and broadcast an output signal in a second wireless format to a replacement aftermarket stereo receiver that is responsive to signals in the second format, the replacement stereo receiver installed in the vehicle to replace the original stereo receiver,
wherein the interface device translates signals in the first format to signals in the second format so that the at least one stereo control can be operated to control the operation of the replacement stereo receiver via the interface.
2. The device of claim 1 , wherein the at least one input signal comprises a wireless signal.
3. The device of claim 1 , wherein the receiver is further adapted to receive a signal from a handheld remote control transmitter.
4. The device of claim 3 , wherein the interface device includes a program mode wherein the stereo control device can be programmed via the handheld remote control transmitter and the at least one stereo control.
5. The device of claim 4 , wherein the stereo control interface device includes a memory and is programmable to store wireless signals corresponding to the stereo control device such that subsequent activation of the stereo control devices results in a corresponding wireless signal being transmitted to the replacement stereo receiver.
6. The device of claim 1 , wherein the interface device is configurable to be adapted to more than one different make or model of vehicle.
7. The device of claim 1 , wherein the stereo control is a switch disposed on a steering mechanism of the vehicle, the switch being electrically connected to the original stereo receiver.
8. The device of claim 7 , wherein the vehicle is a motorcycle and the steering mechanism is handlebars of the motorcycle.
