I bought the radio as an exchange unit forthe original VW radio. It was important that a USB port is off speakerphone is untertützt and even MP3 running smoothly. All of these functions satisfies the radio with absolute satisfaction. Couples also clean with Bluetooth on, the voice quality with the beiligendem Mikrofonist fine too. By Belecuhtungsanpassung it is also great and the interior lighting adaptable. The diplay could actually make more, as people have already written in the reviews, but for the price you should not want to ask for anything. Anyway, I'm very pleased with the steering wheel remote control do I have, however, still concerned, because of this there are an incredible number of interface.
