Steering Wheel Interface



The Steering Wheel Interface enables the existing Scania Truck steering wheel audio buttons to remotely control a Blaupunkt radio/CD headunit.

This project involved discovering un-documented CAN messages. Anything Electronics own custom CAN logger, captured streams of live data. These CAN messages were parsed until the hidden messages were revealed.

Fitting of the Steering Wheel Interface product is extremely simple. No cutting or soldering is necessary. All plugs mate directly with the Scania and Blaupunkt connectors.

All Scania steering wheel audio buttons are active. SOURCE, SEEK LEFT, SEEK RIGHT, VOLUME UP, VOLUME DOWN and MUTE. The response of the headunit to the steering wheel audio buttons is restricted to the available functions of the Blaupunkt radio/CD headunit.
