Connecting iphone 5 via bluetooth receiver to AMI

[Suipedali]

I currently run an iPod Classic connected via cable. I've attached a Layen Bluetooth receiver to the cable and paired with my iphone successfully. When I've gone into Spotify on my phone and played a track it doesn't play through the media player, although the spotify app recognises that I'm connected to the Layen receiver. The car display just shows that the system is trying to initialise the device.

My questions are; Can I actually do what I'm trying to do? Do I need to access the "Hidden Menu" and make some changes? I can't seem to access the "Hidden Menu" via holding down the car/setup buttons together.

I own a 2013 Audi A4 Avant Black edition.....any help will be appreciated.

Which system to you have fitted? Concert/Symphony or MMI?

As soon as I posted I realised I needed to add that. It's the MMI.

Does the 3G+ system not have bluetooth streaming as standard?

i know people use tune2air with ami if really needed and not had problems.
