Audi Bluetooth Retofit A4 Cabrio


Registered User
Hi all,

I've recently bought an A4 cabrio B7 2006 it has an RNS-E mrk 1 with Bose fitted but no bluetooth.
Im thinking of fitting an Audi bluetooth unit in, apart from needing to get the Vcds coding done, Im confident to fit it myself.

After looking at the car i found that it already has a mic fitted in the overhead reading light panel.

My Question is where does this cable come out ? is it possible the harness could already be in the car but the BT unit is not? Iv'e had the head unit out but couldn't see the BT loom / connectors.
