Probably asked already if so my bad
Just bought an a5 sportback. It's a 2014 3.0 tdi auto black edition. It doesn't have Bluetooth audio, just phone calls. But I do have the mmi in the glove box however it won't let me play music via amazon/Spotify any advice how to get it to do this or can I put in an aux port it doesn't have one in the armrest thanks
