Installation was thanks to the panel and CAN bus interface in a Golf 5 Year 2008, no problem. By activating the Loudness function and plays little rum with the sound settings, then it's amazing as opposed to the old normal radio.
Otherwise, all is working properly - dim function thanks to CAN bus also.
The included microphone is small and compact, cable length very long, so you can lay it well without it is visible.
Buy recommendation!
