Functionality isn't good if you use it with car multimedia system. Every Times when you press break pedal this item switch screen to front camera. It is uncomfortable when you drive in traffic. When you turn to rear shift with pressed break screen don't show distance because item mixing front and rear distance information and on the screen you can see incomprehensible mix. One of sensors was defective, parking system sounding conditions. If you use this system with dedicated monitor my be better, but the algorithm is the same.
thanks. very good prodect
