Concert II - How can I play music through phone?
 

I have a Audi A4 Cabriolet (B7) 2006 with the Concert II radio (not the + version, and not the multi-CD version), what way would you recommend to connect an iPhone7 for playing music via spotify?
I'd prefer to connect by bluetooth instead of aux cable if its possible, I don't really want a hands free phone call system though, just a way to play music from the phone.
I've googled this and it looks like there are a few systems that will add an Aux In cable, SD cards, USB ports etc. but they have the older 30pin iPhone/iPod connection and I'd need the smaller newer lightning connection.

All advice much appreciated - Thanks

I was in the search of the same thing for my A6 2005. I ended up purchasing this device and it works great. I had some issues playing the music at the beginning but while someone called me the MMI (2G) showed all the information and call quality was really good. Then I found out that I had to connect 2 bluetooth devices to my phone, I think one is for calling and the second is for music. Once both were connected I could play music through bluetooth with ease.
