I bought car adapter AUX Link almost one year ago. Totally satisfied. Perfect sound, no technical problems so far. Had to spend more time than I was planning to install it, but finally it worked out well (I did the installation on my own, but at any specialized workshop you can have it done in no time). I was buying in the online store AUX Car Kits. It's official store so they have lowest prices (at least when I was buying it) and free shipping worldwide. As for advantages of AUX Link, it can be also used as a charger and a Bluetooth hands-free car kit. Moreover you can control the music using the buttons on the steering wheel or on the car acoustics system. Highly recommended.
