Thanks for the welcome, I recently put a deposit down on an 09/09 A500, I collect it on Friday.
It never occurred to me that a car less than 5 years old would not have an AUX in socket.

As I understand it the Blue&Me system connects to the head unit using a standard iso connector. So all you need to do should be get to that line level cable and piggy back a line in socket to it.
Tackling it from the head unit end, you could run a cable from the stereo down the back of the fascia and out of the ashtray perhaps. Does anyone know how you might remove enough of the fascia to run the cable?
Alternatively, does anyone know where the Blue&Me decoder hardware sits? It might be easier to run a cable from there.
In case you are wondering why I am not happy to use the Blue&Me interface, I listen to audio books on my ipod a lot. The ipod has a “skip back 30s†button which is invaluable for audio books. I don’t think that function will be operable if connected through Blue&Me.
