I have an '07 Audi A4 Avant with no navi or Bose. Anyone have a radio wiring diagram. I looked at the posts and the car datbase...

I attatched (I think) a picture of the schematic atop the radio. The plug colors are (from the schematic):
brown (bottom right)
Black (Bottom left)
Blue (Top Right)
Green (Top Left)

It looks like the blue and green are for external accessories, while the black and brown are standard VW/Audi plugs, but there are only 4 wires for speakers. I know there is an amp and sub located in the right rear of the car.

Thanks posted_image

Can't see your picture but blue should be carrying rear right left and common plus possibly amp trigger.

Looks like the blue plug has three wires in it. I am assuming (like you had said) it has right, left, and common for them both. How about the sub. The green plug has a a pair of brown wires going to a single pin, with a green and white (possible light yellow) on either side.

Thanks for the help so far!

Alright, If I could delete the last 3 posts I would. I tried to upload the picture 3 different times (sizes, formats etc.)

Oh well here is what the diagram on top of the radio says.

Green
(Tel AF +)(LINE RR)(AU PL)(Line FR)(Line [ground])(K LTG)
(TEL AF -)(Line RL)(blank)(Line FL)    (blank)    (blank)

Blue
(Clock)   (Data in)(CDC [switch])(SDI CD-R) (SDI CD-L) (AUX-R)
(Data out) (BOSE)   (+ U CDC)   (Aux [gound)(CD [gound])(Aux-L)
