ViseeO Tune2air WMA1000 - Wireless Bluetooth Music Interface Adaptor for in-car iPod Integration (Audi, Volkswagen, Mercedes etc)
This is exactly what I needed for my 2015 Audi A4. No more weird reaching into the glove box to hook up my phone. It was shipped to me in the US from outside the country and the anticipated delivery was weeks. It arrived much faster than that (less than 2 weeks). I'm very happy with it.
