Product Description  
This Rearview Mirror/Monitor, when used with a backup camera, is designed  
to assist the driver by providing a clear and wide image of the area behind the  
vehicle whenever the vehicle is shifted into reverse. Never rely solely on this  
product to ensure the area is clear of children and/or obstructions. Use your  
monitor and look both ways. This is not intended to replace existing safety  
procedures, but to add an additional safety tool for your vehicle.
