11/29/2015 The cheapest, easiest way to do it is –

1. AMI to Auxiliary cable – works with all 2G & 3G .

2. USB Dongle – 

3. Extension if the auxiliary cable is too short

09/18/2015 – I modified my 2008 Q7 – MMI 2G AMI cable and build a black box to play iPod and stream audio from my iPhone and my wife Android phone on the fly without removing any of the players.

You can add USB host by connecting pins 17 & 18 for data and 25 & 28 for USB power

My sister new 2016 Q5 still comes with a 30-pins AMI cable for old iPods and iPhones, amazing. She’s been using and updating her devices so current that she doesn’t have any 30-pin devices any more. She asks me to help her to be able to stream music and navigation from her iPhone 6 to the MMI 3G plus. I found the website with the information and did it. Now, I can make a cable that works with all MMI 2G and MMI 3G, it’s simple, not that hard, just need some soldering skills.

AMI Pinout

The easiest way is to use a small screw driver to push the 2 big lock tabs on both sides in and up, then just pry the top cover open up.

When the top cover is out, just slide the bottom cover out easily. Split open the metal case from the TOP.

Solder a 1k-1.1k ohm resistor (1/4 watt) across the original resistor 18.7k ohm to have .95-1k ohm across. Pull the iPod wires out. Put some small shrink tubing or cut the wires. Bundle them together and fit them back to the case.

  • Hello,i have AMi cable which works fine with Ipod and have an Iwave bluetooth which powers on when connected to AMi cable 4F0051510K which when connected to iwave it works and i can pair to my phone but Audi AMI says audi ami device not connected.do i need to change the resistor only or disconnect ipod pins as well in AMI?
    i can solder the resistor if i need to.My car is not 2G or 3G,no MMI or nav.
    Appreciate any response.

    • Hello nam,
      The AMI must be in auxiliary for Bluetooth to transfer music, but when the AMI in auxiliary mode, the usb power is off, you need to supply power to the adapter 5v. Follow my video.
