I just purchased on 07 Limited and was surprised to learn that backup sensors were not available. I checked the net and found an alternative. I ordered a Dolphin hitch mounted ultrasonic wireless sensor. The device plugs into the 2" receiver and the 7 pin contector. It only operates in reverse. There is a small speaker/light device about the size of a lighter that goes in a 12 plug. The closer you get to an object the faster the sensor beeps and the light turns from green to yellow and then red. Since the genious engineers at Toyota only provided one power plug up front, I plugged the sensor into the rear power plug and can easily hear it. So far this is a good way to overcome a safety problem and it is only about $170. You can also transfer it between vehicles. I plan to also use it on my RV during trips. If you have kids or dogs -- consider getting one.
