Wiring for Audio 10 w203

[pinapplex]

Hi! I have installed a Audio 10 CD in a 2002 w203, but I canīt get the steering wheel functions to work. I suppose there should be 3 DIN (?) plugs in addition to the antenna, but I only found 2 in my dash, one I guess goes to the speakers, the other supply power and perhaps some other controls.

So my guess is that the 3rd plug controls the steering wheel functions...

Does anyone have any knowledge on this?

Thanks! Jm

Did you connect the fiber optic cables? It would have been connected to the radio you replaced.

I needed a cable. I bought it and connected it to a canbus distributor I finally found by the passenger footwell after looking everywhere...

Now everything works!
