The Steering Knob with secondary functions
Technology
When the driver activates a button on the control unit, the command is sent through an existing wired connection from the steering wheel to the dashboard where it is analysed by the main electronic controller.
The appropriate function is then activated, like it would by the original controls. The use of a wired connection makes the system perfectly reliable in all circomstances. No battery is needed like it would with infrared systems.
The system is programmable to fit the specific wiring requirements of each car. It can be installed on all cars with automatic transmission including cars with multiplex electronics.
The electronic circuits have been tested for electromagnetic complainces. See EMC Test.
