Installation is unbelievably simple and quick, the manual is illustrated and provided with additional text. Even without the additional tape holding the construction with me very well. The position is to the right of the center console below the vent. So relatively close to a built-in navigation system. Nevertheless, it could possibly interfere with one or the other, that it is too far away and the view far different from the traveling direction.
By installing the flow regulation of passenger air is a bit more difficult to achieve and probably hakelig for thicker fingers. Can not say how that will interfere, so far I use this control in the cars rarely. Whether the air stream is deflected unfavorable, I can not say yet.
I am after purchase and installation date and will satisfy the everyday usability in the next few days, however, the sample stellen.Bisher the device fully meets my expectations. Therefore, even a perfect score.
