Now for praise:
.) The installation was fairly easy. Only connection to the reversing lights, I can not recommend it because of the construction of a wireless connection takes a few seconds to complete, which is especially when maneuvering in tight Pakrlücken unnecessary amount of time needed, because the connection each time the reversing lights go out, is interrupted. So I connected the camera to the plate light and activate the wireless connection on the mobile phone when I turn into the destination street.
.) Playback is unfortunately a slight delay, but in such radio systems I see it as normal.
.) What you should keep in mind: In some cars (eg when my FORD Mondeo Turnier 2007 -> ...) Camera Disabled access to the tailgate -> Either you have thin fingers, a Fernentrieglung or mounted the plate holder upside-down (which is possible because the camera expansion with little effort and is reversible).
