Front parking sensors
I am wanting to install front parking sensors on my 2006...However I want them to work like factory sensors and only turn on if I am below a certain speed (say 5 MPH). Is there a wire in the car that will only show positive or negative at slow speed? Maybe I could somehow tap it to the headlights since the AFS only operates with speed? Or the VSS? Any ideas and solutions would be appreciated.

What I saw in a Toyota Kluger that a friend bought (though you guys might call it a Toyota Highlander, was that there was a switch that you would press to turn on/off when parking. I personally would find it annoying in stop start traffic that the thing would beep every time. Note I have been interested in doing this to my car as well.

@spacecraft - They actually were offered as a factory option on the second gen RX...Just not in the USA. And I don't want the factory sensors, that would be too expensive to install. I want to know how the speed wire works so that I can install aftermarket sensors but have them act like the factory sensors would work.
@draco - the front sensors don't beep at as far of distance as the rear sensors do...The front sensors only start beeping about a foot away from the object it detects. So even in stop and go traffic it would not beep unless you are really REALLY tailing someone.

Some 2nd gen RX were indeed delivered with the parking sensors, but it was a dealer installation, not a factory option.
I'm not 100% sure about how the integration (if any) with the rest of the onboard electric system worked, but I suspect they just placed a beeper somewhere, as you would do with any aftermarket equipment....
Not a clue about other markets, like Japan etc.

I had my parking sensors installed by a car radio/alarm shop. I am sure you can swing by any such shop in your area and get all the info. you might want directly. Good luck!

A little update. I was just looking at Cobra's website again, since they make the only parking sensors I have found that work like and work as well as OEM sensors. They modified their parking sensors to be speed sensing for automatic activation/deactivation. YAY!
