    I want to change the setting on the back-up beep from constant beeping to just one beep. Before I buy an OBD2 interface, I want to make sure I know where to plug it in. As near as I can tell, it's not mentioned in the owner's manual, and it doesn't seem to be where it was on the 2017 Prius Prime. I've been under the dashboard with a flashlight and mirror and still can't find it. Anyone know where it is?

    It's under the left side of the dash right below hood release lever. In the photo below the white socket is what you are looking for.

    I know there are currently four different ways to customize the reverse beep.

    1. Ask the dealer to perform the customization using Techstream. Result vary by dealers from free, charge for labor, or simply a refusal to perform.
    2. Use MiniVCI and techstream to DIY ~$30 for MiniVCI and pirated techstream (authentic one is way more expensive)
    3. Use Carista dongle and it's app ($20 for dongle + subscription, but you can get free 30 days trial and cancel it for a free app)
    4. Use Bluetooth ELM327 adaptors like ODBLink LX and Prius Tweak app (available only in android sideloading) $10~$50 for the adaptor, the app is free to download

    It is ridiculous that they could charge or refuse.

    First, Toyota should have given the owner the ability to do this themselves on the MFD.
    Second, since they didn't the dealers should be required to do it free. The constant beeping is not, in my mind, a safety adder but a detractor. Hard to pay attention to other alerts when you are trying to tune out the unnecessary "warning" that you are in reverse. No sh1t Shelock, I put it there ON PURPOSE!

    Why should this be a requirement? And how would this be implemented - a new law?

    Required by Toyota since they have removed the owner's ability to turn off (to the extent possible) the back up beeper. There is nothing "safer" about an annoying beeping the entire time you are reversing. It isn't warning people outside the car, it is "reminding" you that you are in reverse. Rear collision alert would be a lot more obvious if the rear beeper wasn't sounding.

    Thanks to everyone for your advice and instructions. I bought a Veepeak OBDCheck VP11 (for Android and bluetooth) for $9.99 on Amazon. I received it today (6 days without Prime), downloaded the "Dr. Prius" app, plugged in the VP11, started the car, made the connection to my phone and to the app. The first check-box and the app screen was to "turn off the backup beep". I checked that box, put the car in reverse, and just one beep! DONE. Thank you!
