'06 Lx470 Backing Sensor Doesnt Work, Need Help!

[NMon]

I've just bought second hand '06 LX470 recently. It has backing sensors mounted in back bumper. But it doesnt give any "sound warning" when I reverse. Does anyone experience this, and found way to fix it? I searched through the forum, but havent found any topic related to it.

Correct me if I am wrong but I do not think any of the LX470's offer the back up sensors. Just the rear view camera. Can you post pictures of the sensors you see? Maybe it was an aftermarket job. But then again I see you live in Mongolia? Maybe it is different than the U.S. model.
