Move 'Reverse' beeper to back bumper. Anyone done it?

1) Has anyone found that little F'er (beeper) under the dash? (where and how easy to access?)
2) And moved it to under the back of the car? The aftermarket back up alarm I installed on my box van is WAY louder than would be appropriate for a small car. I MUST stop that noise in the cabin, but would love to have that beeping be heard at the back of the car, "IF" it would sound subtler at the back of the car for pedestrians.

I was just very glad to read that the dealer will turn off the Reverse Beeper (usually for free I am told), since I am due for the 5k service next week. But if this Mod has been done to good effect, I'd like to try it first. So any How to's on removing beeper, running wire to rear of car, mounting location(s) and was it worth it, would be greatly appreciated. Was the beep sound no longer obnoxious in the cab? Was it obnoxious for pedestrians?

For those with Reverse alarm turned off, did it also turn the seat belt alarm off, or is that a separate step? I would love the dealer to turn off the seat belt warning. Anyone had this done or know if it is allowed by law (in Calf. if that matters)?

TMI: Being a Mac person, I was NOT looking forward to learning to download a CSV file onto an old PC of my wife's and trying to use my Torque App to disable it. Now excited about the 'possibility' of turning a lemon (cabin beeper) into delicious lemonade (exterior beeper).

 

I see now the other option is One beep. This is good. Now I'll get to see if Dublin Toyota service dept. will turn it to one beep for free, or if I have to get the salesman involved.

I still would like to hear of anyone moving that beeper to the back bumper. I'm going to have to check how effective the white noise (in EV) is from the back of the car. Is there only a speaker in front for the white noise?

This Bak-Talk unit looks interesting, but pricey.

It supposedly 'talks' only when there is something in your path. Saying: " Eight feet, five feet, two feet, (under 12") 'Crash'. " Would be good if it really was quiet w/o annoying false alarms.

Anyone seen or heard of these Bak-Talk units before?

 

Called for 5K appointment. They said the Entune 3.1 update and Reverse change to one beep were free (she asked if I bought my car there, which I did). Se was not aware they were able to turn off the turn signal alarm Seatbelt Alarm. I told her it was listed on page 646 of manual. She called back in an hour to confirm that they could indeed turn off the seatbelt alarm (all three for free). Good to know in advance. )

 

Dooooh! Thank you! Post edited

 

I wanted to see how well I could hear the PiP's white noise speaker from the rear of the car. While my wife was backing down our driveway, the 'noise' was on and off. We figured it turned off as she applied the brake backing down the slight grade of the driveway. Even when 'white noise' is on, it is not as audible behind the car. Hmmmmn. Maybe instead of looking for an aftermarket noise maker, I'll look into mounting a second factory 'white noise' speaker at the rear of the car? I'll do some more listening...
