If you go to navteq's website and search for an upgraded map for a 2005 A6 the website says, "New updates are currently available for your navigation system, but can not be ordered from this site at this time." A similar search for a 2005 A4 yields, "There are no updates for your vehicle at this time."
Didn't both the 2005 A4 and A6 have a RNS-E option? Shouldn't it be the same disc?
