Answer per Audi: basically none of it works while in Europe
None of Nav, Connect or SAT work in Europe per the European delivery contact. Per the Audi ED customer agreement, they will give you a portable GPS unit to use temporarily on an as available basis if your vehicle came with factory Nav installed.
The iPhone (or other) AMI connector cord is only provided at final US dealer delivery, so you need to either bring one with you or buy one at the factory store if you want to use AMI there.
And, for a Q5 w/ standard roof rack, the bars are boxed in the back of the vehicle at Euro delivery point.
