Steering Wheel Audio Control Interface

Description features:
The Third Generation of Universal Interface of Steering Wheel Audio Control System The first generation: There is only one signal input wire, which can be connected to all Korean cars and some of American cars. No need to tear down original steering wheel, you just need to connect the right wires of the steering wheel. The second generation: There are two signal input wires, which can be connected to all Korean cars, 99% Japanese cars, European cars and American cars, no need to tear down original steering wheel. Connect the wires as instruction tells, then it works. The new generation of universal interface of steering wheel audio control system has improved a lot. Details as following:
1. Cubage is much smaller than the second generation. It is only 1/3 of the second generation. It saves room for installation and it is more convenient for installing. (Only half of Nokia 6030) 2. There are four signal input wires instead of two signal input wires in the second generation, which makes more brand cars available by easy connection without any teardown and adding any other parts. It can be easily installed in Picasso (with controller in the both side of the steering wheel), Buick Regal (with +12V data output wires), and so on. 3. There is an external extended wire for IR transmitter, which makes it is more convenient for hiding the interface when refitting. 4. Solved the problem from the second generation that doesn't support Foryou dvd player, one model of JVC DVD players and Eclipse head unit. All head units with IR control function are available.
5. There is a data input wire for updating to the fourth generation. The third generation can be updated directly into the fourth generation, no need to change the third original steering wheel controller. There are connecting function instruction on the bottom Universal control interface for vehicles steering wheel.
