So one of the Installs I did a while ago when I had my old 3G setup was the AMI install, I also used the same setup in my 3GP install as well, just needed a different configuration in the green menu.
I really don't like the idea of the AMI in the glove box on the C6 it was a rubbish idea especially if your using your iphone as the music source, so you have to reach over every time you get in and out of the car. I also been looking around for a pre-made cables which even on ebay they are going for £150 to £300 which is a complete joke for what it is.
So here is a write-up of making your own cable and installation which i'm going to put under the armrest.
So the parts required.
AMI extension cable (this is from a part from a VW) Part number on the connector is 7L6 035 727 changed to 7E2 971 199 (harness) the harness is expensive if you buy from VW I got one from Poland for 30euro
LVDS cable this is for a BMW.... cost was 19 euros delivered from ebay
New section of cable you need at least 14 core + the screen
12 Pin connector to go into the back of the quadlock connector ignore the part number on the photo it is now 3B7 035 477 B
Quadlock pins you can buy 20 for £6
So to making the cable.
First is to remove the cover at the AMI socket end.
At this point desolder all the cables, and solder up the new cable, there are some differences between the VW & Audi setup on this cable I purchased which are shown in the picture below, all the points that were desoldered should be soldered back up with the new cable.
Once the soldering is done at the AMI end you can connect the pins to the quadlock connector
You should also cut off the end of the LVDS cable and strip about an inch of the wiring back, so you can solder up the the 4 wires.
The pinout for both quadlock & LVDS is listed below
After you have done all that you should end up with something like this.
I was doing some other work to the car at this point as I needed to replace the cup holder in the center console so had to take out all of the climate controls and MMI controls and surround, which you don't need to do if your just fitting the cable as you can run the cable going to the glovebox and run it behind the carpet trim.
First was to remove the side trims, there is one screw under the drivers & passenger foot well to remove.
Once the screw is removed you can remove the trim by getting your hand behind the trim and pulling away from the centre console, the passenger side is a little tight as there is not much room between the seat & console.
You can then start to remove the rear section of the console, you have to remove the air vent first either by pushing on the back of the vent or using a hook to pull the vent out. Don't hook onto the front vent you will on break them off the hook point is right at the back of the vent at the bottom.
Once the vent is removed you can access the screw holding the armrest in, if you have factory fit phone prep you will also need to disconnect the wiring harness
Next was to remove all of the rubber mats under the armrest, and remove the screws holding the cup holder and rear console in place.
The rear section is also held in by clips either side of the console at the back, you don't need to touch the screws
Rear console removed.
Once you have the rear center console out it time to start hacking around with the dremel...
First to flatten out the area where you going to fit the AMI connector.
Next is to mark out the hole using the connector as a template.
Don't worry about it looking a bit untidy as there is a cover to go over
You then need to trim the AMI connector to allow it to clip in place, you trim down these edges to allow for the thickness of plastic.
AMI fitted
Depending on where you fit the AMI connector you will need to slightly trim the center console support. I trimmed my in the area marked in red but the screw and most of the plastic was still left
Pic with the Rear console in place, remember you don't need remove the front center console or the climate controls
Final stage of the installation is to connect the cable to the back for the Audi Multimedia module, to do this you need to drop the glove box. To remove the glove box first start by removing the end panel on the left hand side so you can see the fuse holders, you then remove the 2 screws underneath the glove box on the left & right hand side, then open the glove box and remove the 3 screws at the top of the glove box.
Once removed you can get get access to the quadlock connector.
At this point you can remove the glove box to make it easier to run the cable and connect into the quadlock
The other connector goes in the yellow connector shown in the image below.
Once fitted it then best to test the cable before you start putting the car back together.
First enable the hidden menu, you will need VCDS to do this.
[5F - Information Electr.]
[Adaptation - 10] -> Channel 6 -> Change 0 to 1
Save and Exit.
You should be able to access the hidden menu now by holding down the following buttons CAR - SETUP if you don't see the hidden menu then you may have to reboot the 5F module, you can do this by holding down the Setup, Joystick, and top right control button hold down for around 5 seconds then release.
Once in the Hidden menu select Diagnose, Settings
Select AMI/AUX from there I selected option 5/8 as this will allow streaming of music via BT (once I get the AMI BT adapter)
Press the return key a couple of times to exit the menu and reboot the 5F module.
once the system has rebooted select he CD/TV or Media key, and the top right soft key (Source) you should now see AMI in the list (IT will be grayed out if you have not plugged in a cable and device)
Connect your cable to the AMI socket, I plugged in a USB cable & memory stick and you should see it come to life
Installation is now complete you just have to put the car back together....
