A8 Noob - MMI 2G with Bose Aux In

[Oodoom]

Hello gents

Am picking up my first A8 tomorrow - a 2007 Quattro SE 3.0 TDI. Am very excited!

From reading the forums in the last week, Ive realised that the ICE system on this car is a bit of a complex beast and Im sure I will be asking many daft questions over the next couple of weeks. So here goes, the first round of daft questions:

My car has a colour screen, nav, a 6 disc changer in the glovebox and a dvd changer in the boot. Theres also Bose badges all over the interior. So, from this Im assuming I have an MMI 2G High system with the Bose option?

When I select 'Manual' in the systems menu, it says the disc is missing - there is a Manual CD in the owners pack - where does this disc go? In one of the 6 slots in the glovebox? And should its stay there or does it install on the system and can then be removed?

I listen to a lot of music but all my CDs are in the loft - so I must have some kind of Aux In. It seems that there is no Aux In on the MMI system unless my car has the AMI option - which it doesn't. I'm not about to spend 500 quid on an all singing all dancing interface that fully integrates with the MMI, I'm not bothered about controlling my phone from the car controls, I just want a cable that I can plug into the phone. So, what is my best and cheapest option for fitting an Aux In? For example, will this work with my system: http://www.xcarlink.co.uk/product.php?productid=61 - Does anyone have experience of fitting / using this unit? Any other suggestions gratefully received.

Thanks in advance!
