Hi Everybody,
Just picked up my 2005 C180K Sport with the Audio 20 headunit. I don't have the cd changer or the phone pre-wiring.
My problem is whenever the Audio 20 is turned on, there is no sound, and the volume wheel doesn't work (neither do the steering wheel controls). Pressing the mute button twice (mute on, then off) unmutes the audio.
How do I prevent the radio from being muted when it's turned on? I've read the manual cover to cover, and searched these forums, but no joy.
Thanks,
Matthew
