This kit is the 4 sensor system. The production has CE certification.
Please be aware that your insurance policy will be void if any electronic device without 'CE' approval is installed on your vehicle.

• Suitable for cars with towbars. If one of the sensors detects a towbar, the sensor begins to learn about it. The sensor will then be aware of the towbar's presence, hence it will not activate (bleep), ignoring the towbar but not other objects.
