B Class bluetooth connectivity

[Jakerook]

Good afternoon all. Would you be kind enough to give me some help. Can anyone advise what I need to get the bluetooth for the phone working on the A20 sound system. I believe it to be able. I have attached two photos of what I have under the centre arm rest. Many thanks

For that you would need to replace the head unit:
