Managed to get this sorted for anyone who's interested, now have full iPod control and also got a Bluetooth module so I can stream music through the MMI also got hold of a genuine media holder, was a very easy job, on the back of the nav unit there is a fibre optic input, found the original ami wiring on eBay, plugged it into the nav unit all the power plugs straight into the original connector block, enabled AMI/AUX in the green menu job done, theres already a location for the AMI socket in the glove box you just have to cut the tabs away and it enable you to slide the AMI socket in
Also found some genuine A6 under seat storage boxes
Also managed to get me an RS6 gear knob...
