2004 A6 Cell Phone Install
I do not have OnStar. Here are some of my questions. Any answers appreciated.
Where is 2004 A6 equivelant of DB-25?
Does 2004 A6 have built-in mic?
Does 2004 A6 have built-in nav/phone speaker? Or, can it use audio when muted?
People have been able to integrate with the newer system, but I don't know the details.
If you want to find switched, unswitched and ground, it should also be on your 10 pin.
That's it. The radio is already wired to the B pillar speaker.
Here's a picture of my hook up on my Nav Plus unit, only shows the speaker hook up, but essentially the same. I just did this on an 00 with a blue tooth, couldn't be easier.
