I am helping a local AWer install a bluetooth kit (HCB-30) in his A6. It was taken out of his former car, and I do not believe that he has the installation instruction book. First, I wanted to confirm the wiring:

Red - constant power (with integrated fuse, but I am probably going to switch that to an inline fuse)
Blue - ignition powerBlack - negative ground
Yellow - mute

Is this correct?

The other question I have is whether or not the yellow Mute wire works well with the Audi head unit. I read on a support forum (I think from the UK) that the yellow wire sometimes does not carry enough current to trip the mute function in radios. Does the yellow mute wire work well with your factory head unit?

TIA for any help!!!
