No handsfree Audio

1 post in this topic

Hello, I'm not sure if I should make a new post for this, but I have tried everywhere and can't get an answer. 

I have a 08 A4 B7 with RSN-E unit installed. It has nav and sat radio. a couple years ago (2015) a friend wired OEM bluetooth module but never coded it because they didn't know how. I recently bought a VAG cable for something else and decided to finally code it. The problem is the bluetooth connects but I have no audio, the person can't hear me and I can't here them. There is a mute symbol at the bottom of the screen during a call but once the call is ended all other audio is resumed. (I can hear nav or radio) 

I posted a link with pictures of the coding and the harness wiring so any help would be nice. Thanks ya'll.
