Won this off ebay last week, was listed as "2004 audi a3 sat nav" with a buy it now of Ł450 so i snapped it up
Ordered the GPS antenna and 4 audi cd player removal pins so once they arrive ill get it installed.
Ill take some pics during the install and do a write up to help anyone else thinking of doing it.
Think it should be pretty simple, need to move a wire for the bose to work but apart from that i think its plug and play
ill update this with any progress, heres a few pics of the unit:
