I’m going to modify the cable to use USB host to connect hard drive, iPhone, Android, bluetooth, all in one.

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.

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 did diy android all in one for my q5.

    and there was sound problem and i so your post and i modified my ami-ipod connector with aux cable.

    happilly, it kinda works, with bluetooth, video, but, everytime i use navi, the guide of direction is cut in half, or just one word, and it became blank…

    i was searching some more, and i think, maybe it happens because lack of vatage of the ami connector… for the two gadget. today, i was playing music (since media is connected to ipod) sametime, youtube with my phone, both sound came out to the speaker, and i didn’t like the music so i change the music, in between change of music, i notice, my phone (connected with android all in one) sound became much louder. and when music start play from ipod, it became lower again. and kinda remember, when you modify yours, you change some parts…

    can you give me any tips to fix this problem?

    or do you have any idea, where i can get the aux beside ami connector?

    thanks for the reading this 🙂

    have a wonderful day! 🙂
