Simple - Super - good packaging and very good quality and also works perfectly. I bought this adapter, because the Audi Neckarsulm center could provide me a functioning adapter for an A5 convertible with a iPod. According to them there are Komptibilitätsprobleme with some models. Not so here: Have this adapter plugged, iPod drangehängt and the device is recognized immediately. That the non-functioning original Audi cable 41 Euro (!) Would have cost is also worth mentioning. Although the cable comes from overseas, but 1 week delivery time was not unreasonable at this low price.
