The CM-50 is a four-way control lever with three non-volatile memories, which is attached to the steering column of the car.

There are three additional switches at the ends of the lever under which speeds can be saved (e.g. button1 – 50km/h, button2 – 90km/h), which remain in the permanent memory of the device.

A constant speed LED indicates whether the system is active or in standby mode
