Reasons Why
The AutoZonic system is a safety device that accurately detects all objects, as children, toys, pets, another autos, etc. that are behind your vehicle while you back up. The beeping as well as LCD display inside the car warns the driver of the danger and prevents a potential accident.

But, the most important thing is that by installing this system you can prevent injuries to adults or worse children.
These statistics confirm the increase of these types of accidents.

According to the Department of Transportation, 27% of all accidents occur in reverse. Further research showed that 70% of these accidents could have been prevented with the use of a collision avoidance system as AutoZonic.
How does it work?
This system is automatically activated when you engage reverse gear. Small sensors are located at the rear of the vehicle, they send and receive ultrasonic radio waves, which bounce off obstacles and alert you to their presence. There is an internal buzzer that gradually increases in frequency as you approach the object and shows you the distance in the LCD display. A continuous tone and the red color in the LCD display background denotes that you are within 1ft (0.35m) of the obstacle.
