I purchased this lead as the new A4 I have has got the Audi Media Interface installed and this would enable me to link my i-pod to the car stereo. This works perfectly fine and enables you to search through artists, tracks, genres, playlists etc via the main unit or the controls on the steering wheel. It arrived promptly and was packaged up with VW logos albeit the slightly wrong shade of blue but to be honest it's an aftermarket cable that cost c£4 so I'm not concerned about this in the slightest.
The only reason that I have given this 3 stars rather than 5 is the fact that postage costs were also around £4 and when this arrived a few days after being ordered it was in an envelope with a first class stamp on it. I have no complaints about the total cost which I'd obviously agreed to at the point of purchase but I find it very annoying that either:
a) they are employing very highly skilled and therefore expensive members of staff to stuff things into envelopes
b) profiteering from stuffing things in envelopes
c) pricing the product up incorrectly in the first instance to attract purchasers and recovering this via the handling fee
Conclusion - product is great, delivery was prompt it's just a shame about their pricing/postage policy which annoys me.
