Up for sale is my Audi MMI Bluetooth adaptor. This was used in my 2012 Audi A5. I traded in my car and the dealership didn't want it. It allows you to play pandora, Spotify, Apple Music and more wirelessly in your Audi that doesn't have a music Bluetooth connection. Bought for $95 new plus tax, in perfect working order. 

It's made by a company called "a2dp4audi.com". It's a modified MMI iPod cable that is able to provide power to a 32-pin iPod Bluetooth adaptor, and the car treats it as an Aux line in. If you've done your research online then you'll find that a2dp4audi comes highly recommended on many forums, etc. 

Note for those that haven't done the research - while it is a very convenient way to play Bluetooth music sources in your pre-a2dp car, it presents audio as a line-in so does not display album artwork and song title in your MMI display.
