It’s a radio-wave device that groups the auxiliary controls in a unique place on the steering-wheel, on the right or on the left, according to the user’s requirement.

It has a button-board with a handle allowing you to manage, by the sound limb, the wheel and the following controls: arrows, windscreen wiper, horn, emergency lights. The size of the
power-box is very small, while the surface of the griffe staying in contact with the wheel is very large. When you do not use the  above device, you can easily remove the handle and the button-board, leaving the wheel on the griffe.

You can place the power-box in any point on the ring of the wheel.

The transmitter sends the impulses to the receiver by radio-waves.

This system can assure you:

A perfect functioning, also when transmitter and receiver are very far from each other.

Lack of interferences with other electric/electronic apparatuses in the car (power-stations, mobile-phones, radios, external electronic signals and other apparatus).

Lack of electro-magnetic pollution.
