I'm really struggling as to what is going on here.

I have an original shaped Allroad on a 55 plate. It is not the new shape, so I guess that makes it a C5 (although it says here that a C5 stops at 2004).

Anyway, I need to fit an Isofix child seat into the rear, but I do not have the Iso fix mountings, can these be retro fitted and if so, any idea of cost and part numbers please.

Next question is ref getting an Ipod to play through the head unit (preferably with the track/playlists shown).
I have the Sat Nav fitted (the manual says RSN-E). Is this possible for a reasonable price or should I stick with 2gb memory cards????

Thanks for your help. Im a bit of a numpty when it comes to Audis, its my first (and first baby too).
