I tested it against a big wheel kids toy and it was sporadic at best DO NOT DEPEND ON THIS TO KEEP YOU FROM BACKING OVER A CHILD. A rear camera would work well in this capacity, my buddy's GX 470 has the camera which offers amazing views but is poor for parking. He backed into a pile of mulch thinking it was several feet away and wishes he had park assist as well as the camera. The 300C sonar is an excellent parking tool when tested against my Jeep.
