Attaching MP3 player/AUX port Audi A3

[garratt83]

Hi

I've just bought an Audi A3 It has a HU with a cass player and a 6 CD changer in the boot. Is it possible to plug a lead in the back so I can use my MP3 player with it. I also have a Ipod, is there an adpater for this out there.

Any help would be great
