What's the beep sensor thing call?

[greatwhite]

I want to install one of them sensor usually located near the front and rear bumpers that beeps when you approach an object. The beeps gets closer to one another as you are closer to the object. A friend of mine had one in his SAAB 93 Aero. I assume there's an aftermarket product out there for trucks. I want to install it on my 07 Frontier CC LE that I just purchased.

Search 'parking sensor' or 'reverse sensor' on ebay.

I bought a set for the rear. Mine has distance and side for obstruction. Also beeps faster when you are close. Be sure to install an override switch. They go nuts when towing a trailer or with the tailgate down (in reverse). I ran a flew conduit from the rear bumper to the engine well since the sensors are connected to the processor via thin coax cable. I paid $35 on EBAY. Mounted the display in the center of the dash. Processor under the dash. Kit uses 4 transducers. Even came with a hole saw for the bumper. Search for backup sensor.
