Would anyone know where I can get the complete AMI retrofit with the harnesses needed to replace the CD changer and add it to a car that didn’t have it?

After doing a lot of research, I wanted to document the AMI retrofit for posterity.

This is mostly for people who buy a Gen 1 R8, want to connect your phone via Bluetooth to play music/show song name on screen, and want to keep the OEM stock look.

AMI is Audi Music Interface for playing music from iPhones and other devices. It's really only useful today when used with a Bovee tune2air Bluetooth Car Kit (WMA3000A AMI/MDI/MMI Connector) or similar. More historic details are available in this post.

AMI works only with the Radio Satellite Navigation unit RSN-E version 193 (2010-2015 R8s), not RNS-E version 192 (2008-2009 R8s.) The 193 version has the "Media" key on it and the 192 does not.
If you have a 192, you can replace it with a 193 unit, but also have to replace the Reverse Camera RVC module. See this post for details.

There are 3 versions of AMI modules. MOD Bus for MMI, CAN Bus for MMI, CAN Bus for RSN-E. Only that last version is compatible. They are the module from an R8, TT, or A3. The part numbers are 420 035 785 (from R8), 420 057 785 (from R8), 8P0 035 785 (from A3), 8J0 035 785 (from TT).

If you have these parts, then you need a retrofit cable. The Audi part number might be 8K0 051 592 for the cable. But a easier option might be the Kufatech cable. If you can't find a cable, here are the pinout details (also see this thread):
Code:
The pinouts for the CAN AMI are:
1 - "Terminal 31" - Ground
2 - CAN Bus Low (Infotainment)
4 - NF right (low frequency) to radio -R-
7 - "Terminal 30" - unsiwtched 12V (Pin 1 is the ground, pin 7 is the permanent 12V. Terminal 30 and terminal 31 is common Audi terminology for ground and 12V.)
8 - CAN Bus High (Infotainment)
9 - NF left (low frequency) to radio -R-
10 - NF earth (low frequency) to radio -R-

Pinouts from the 2009 192 RNS-E are the same for the 2010 193 RNS-E:
Multi-pin connector, 12-pin, black (T12i)
2 - Signal earth to CD changer -R41-
3 - Speed signal (not used)
4 - Permanent live to CD changer -R41-
5 - K-diagnosis (not used)
6 - CD data output to CD changer -R41-
7 - BOSE code (not used)
8 - Signal (left-side) from CD changer -R41-
9 - Signal (right-side) from CD changer -R41-
10 - Switched positive to CD changer -R41-
11 - CD data input from CD changer -R41-
12 - CD-CLK from CD changer -R41-

The CAM CD Changer (2009) pinouts are:
Multi-pin connector, 12-pin, black (T12f)
1 - Data output to radio -R- / navigation system with CD drive control unit -J401-
2 - CLK output to radio -R- / navigation system with CD drive control unit -J401-
3 - Terminal 31
4 - Data input from radio -R- / navigation system with CD drive control unit -J401-
6 - Permanent live from radio -R- / navigation system with CD drive control unit -J401-
7 - Signal (right) to radio -R- / navigation system with CD drive control unit -J401- / satellite radio -R146-
8 - Switched positive from radio -R- / navigation system with CD drive control unit -J401-
9 - Signal earth from radio -R- / navigation system with CD drive control unit -J401- / satellite radio -R146-
10 - Signal (left) to radio -R- / navigation system with CD drive control unit -J401- / satellite radio -R146-
11 - TOC Check Control (not used)
12 - Terminal 58 (not used)
Installation: The summary is that you need to install the physical hardware, connect the wiring harness (including the CAN bus wires), change the coding of the modules. Full instructions are available here from the archived OEMPlus AMI retrofit kit install manual. The install manual is also included here:

The AMI interface has finally arrived but I'm still waiting for the Kufatech cable. AreAte - did you do this mod? I may need some help, I'm hoping the retrofit cable makes my life a lot easier?

That's a nice looking example! I think the Kufatech cable will greatly simplify the installation process. Otherwise, tapping into the CAN datalink is a bit confusing. Let me know how it goes and I'm happy to help any way I can.
