This is the incredibly rare but also incredibly useful Audi OEM Bluetooth Adapter for the Audi Music Interface. I bought this for my 2013 A4 but now have a vehicle that plays A2DP over the air so I have no need for this. 

It works great and is a great solution for anybody with an Audi Music Interface that does not play music over Bluetooth. 

I'm happy to answer any questions but have a feeling if you are interested in this, you know what it is. 

Buyer to pay in full within 24 hours of winning. 

Thanks!
