This radar is easily installed and works well. Too bad the diagrams in the instructions are in German ... if the document is not very detailed but sufficient for installation. The drill provided is of good quality and the rest elements to my surprise. The sensors are well made and work very well. Importantly the sensor installation: do not put too low, mine are 37 cm from the floor (55 cm recommended against) and detect the ground, in this case we must orient upwards. And pay attention to your vehicle that did not attach to the bumper by or metal parts of the body that could help break at the right height. Attention also to the inclination of shock. To provide a secure installation of silicone and glue and more.
