Phone Mute Function on Bose: Where's the input?
On the '02 Premium Sound, where is the car phone mute function input? I originally read it was in the DB25 connector in the left rear of the car on pre-'02 model, but have also heard that unless the '02 model was ordered pre-wired, that specific connector won't exist. Before probing everywhere for it, does Anyone know for sure where it is on a non-prewired A4? Is it on the head unit itself? Input is totally apprecialted.
