Okay so if this is in the wrong place please let me know.

I keep finding conflicting information about hoe to retrofit AMI to my A6.

I have the MMI 3g Low/Basic on my 2010 A6. DVD NAV with SD slots in glove box and CD changer.

Some people say to just buy the wiring harness, plug into back of the dvd nav system and program it up, some say I need to buy a whole AMI unit of some sort.

What do I actually need? I essentially just want Bluetooth Streaming, thats all. But the AMI interface allows for multiple things to be connected obviously.

Can someone please point me in the right direction on what I need?

Really appreciate the help!!!
