Radio/audio wiring diagram 2004 CLK320?
Hi, has anyone got description of the connectors for the audio/radio unit? Somehow I can't find it anywhere - mostly all the inputs (steering wheel controls etc) as the outputs (speakers etc) are easy to figure out even without diagrams. But description of all connectors would be the best! thanks!

Here's a good resource I found:

Note that things like steering wheel controls, switched 12v and illumination don't exist as individual circuits - they are controlled by the CAN bus. Also, you may not have speaker wiring in the harness if you have the Bose or Harmon-Kardon systems as those use fiber optics to send audio from the head unit to the amplifier.

Super, thanks Rodney (so I guess I will have to skip the steering wheel controls - it will be a bummer if my car also has the fiber optics - I'll find out soon)

There are CAN bus interfaces you can get that will interface wit the steering wheel volume and channel control buttons. Some of those also provide the illumination and switched 12v signals.
