Well, I've just stumped up the cash to get the Audi iPod adaptor and after one day of flicking between tunes, I am really pleased.

I bought and fitted the kit yesterday. The Audi instructions were clear and very easy to follow.

I just popped out the Concert II and un-did the rear aerial and loom.
I disconnected the thick brown live wire from the main loom.
Connected this to the new iPod adaptor brown wire.
Connected the iPod adaptor new brown wire in the old ones place.

Connected the new loom into the back of the loom assembly.

Replaced the Concert II and set out on the glovebox removal.

removed the glovebox by undoing the 7 screws.

Drilled a 13mm hole in the side of the top right compartment and fed and fitted the iPod wire and grommet.

Connected the iPod cable to the little black box of tricks on the new adaptor.

Assembled the glovebox and plugged in my iPod.

Switched it all on and sat listening for about an hour.

I am very pleased. Although i wish they would sort out the text on the Concert II to show playlists and track names.

Still, I do love the Audi logo on the iPod
