Hi all please can you help.

picked up a 2005 A4 avant 1.9tdi sport last night and would like to fit an ipod integration kit.

Firstly it has BOSE and ideally i wanted a PArrott 9200i but after reading about 6 pages on this forum im starting to think its not a good idea.

it has a single CD currently and i think its the concert (1 or 2 how would i know)

how do i correctly identify the head unit?
whats a GEN2 etc? (compatibility list from dension for gateway100)

Audi A2, A3, A4 & TT 1999-05 Chorus (I, II) & Concert (I, II) GWL1AU2
A2, A3, A4 & TT 2003-08 Chorus Gen II + & Concert Gen II + GWL1AI2
Symphony Gen II +
Navigation Plus RNS-E
Navigation RNS-Low (BNS 5.0)

will mp3 txt work? and appear in the computer screen on the dash?

also i can only find 2x holes for removal keys? where i can only find packs of 4x for sell?

Help as cd's are soooo last year and the radio doesnt do it for me anymore


Thanks in advance

Andy..
