Parking sensors

I bought a used 2025 Tacoma SR5 4WD. Got a great deal on it. With that said, I really thought most of the trims came with front and rear parking sensors !! I guess I should have researched just a little more. In my opinion this should pretty much be standard on these trucks !! I checked with Toyota about adding it, and they’re saying the truck has to be wired for it from the factory!!
