Good evening. I’m new here so excuse my ignorance. I recently got a pretty good deal on a 2009 S5. It had and has some issues which I’m working through. It has the bang and olufsen stereo. One of the issues was the amp was blown. I sent that away and had it rebuilt. Got it back today and now I have sound back. Is it really only Bluetooth for phone calls though? Any idea on what needs to be done in order to stream music?
