Addendum: If the camera is stuck at a strongly curved pane next to the interior mirror on the left, the right edge of the roadway is not sufficiently consulted and represented.
But this page is very important.
After all, you can not pivot horizontally this camera (unfortunately)
... The A3, for example, the windshield is very oblique.
The camera lens (inside) can be swung down, the hood is only just visible.
The higher the camera is mounted under these circumstances, the worse is the view directly in front of the car. Deeper down, the camera lens can not twist.
Addendum: Meanwhile, I have to the right side of the road and down very improved by the installation of a "Hama keeper" joint base "4L" the vision (remove the pin on the joint socket and then just with 3M - zusammekleben bonding surfaces)
