Hi, kmartin has not been on this forum for 4 years. Hopefully she returns upon receiving your message. I believe that there are other threads on performing this here without the pdf. You might want to search around.
So, I recently purchased a 07 B9 Special, you know the one with the mesh front screen. I have used the AUX and a apple connect wire from my I phone 8 to the AUX connection under the arm rest. Works great for audio books and other stuff like music.
