How do I know if my car has it?

 

As I recall, those with the Backup Warning will have small circles (as in stamped into) in 3 or 4 positions on the rear bumper when viewed from behind. I think they are the sensors. I don't have it so I can't help any more than that.

 

I have those round things on my back bumper but don't recall anything on the dash. does something BEEP??? Switch to turn it off and on???

 

The beeper for my back up control is under the trim piece behind arm rest/center console at rear seats. It just pulls off.

 

Damn, now I got to look in the trash can for that little speaker that I couldn't figure out what it was for.

 

The height of irony would be inadvertently backing into the trash can crushing the speaker inside.

 

hahahahaaha

That would be hilarious!
