no parts needed to fit it mate - just fitted one in my Dads R32
here is a quick guide
clip the top centre speaker/vent off (prise it out but careful not to break clips)
then one torx screw holding a plastic retainer in, then unclip
then 2 torx screws holding top of centre dash on
then 2 torx screws holding bottom surround on
once removed, this reveals 4 torx screws holding the unit in
very easy really, just take your time
