I have Amazon music working.
You need to login to Amazon - you do this through the Services on the My Audi app. Also ensure that you're phone is connected to the MMI through WiFi. Make sure you also have a data connection - I use Bluetooth rsap (android).
Great when it works!
Just in the process of moving across from an A3 8P 3.2
Picked this up last week, '18 plate, Black Ed, Mythos, loads of options. Pre-registered with Reading Audi, 3k miles.
Quite a different experience to driving the 3.2 - shall miss the V6 in the old girl !!
