Been member here for a few months but I finally found a 6 MPS that was right for me, it came from a fellow forum member (but not advertised through here), even came with an Oz MPS sticker, hurray!
So the car is a totally standard 2006 6 MPS with 81,400 on the clock.
Got to have a nice drive back from Sydney down the freeway with my friend trailing behind in his TT Quattro.
If anyone cares to answer, how do I go about getting either a USB or Aux into the standard head unit?
