Concert II & iPhone (for music not calls)
 

Hi All, it's my first post, and I'm a first time Audi owner - it's a beautiful low milage 2006 Audi A4 Cabriolet (B7) with the Concert II radio (not the + version, and not the 6 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, 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 but they have the older 30pin iPhone/iPod connection and I'd need the smaller newer lightning connection.

All advice much appreciated - Thanks
