Radar Detector / Accessories Dash Mount Setup for Rivian R1T / R1S - Quick, Easy, and Removable

[EveryAmp]

If you're looking for a simple way to mount a radar detector, or really almost any dash mount accessory, you've come to the right place. In a previous post we walked you though hardwiring a Valentine One radar detector to a Tesla Model 3. That installation required pry tools to remove trim and fish cables to a switchable power source, subject to software changes.

For our Rivian we took a much simpler approach. No hardwiring, no disassembly of trim. A simple 2-3 minute installation and we were up and running.

All you need is three items, assuming you already have a radar detector of choice. We're fans of Valentine One but there are many other great detectors out there for your choosing.


Parts Lists

• Rivian Dash Anchor by EveryAmp (25mm/1in/B-Size)

• 3" Socket Arm (25mm/1in/B-Size)

• Adhesive Adapter Plate (25mm/1in/B-Size)

Think of these items as Legos. There's catalogs of components that you can mix and match to build nearly any type of rig you want. The other great thing is you do not need to stick to one manufacturer of these components as they all use industry standard ball sizes.

Tools Needed

• Philips Screwdriver

The Install
First insert the Dash Anchor behind either side of the main display. I chose the passenger side for the radar mount, since I have my phone mount on the driver side.

Summarizing our instructions page, once you feel the anchor click into place behind the screen you can secure it into place by tightening the screw with a Philips head screwdriver.

Attach your adhesive adapter plate to the underside of the radar detector.

Use the socket arm to join the adapter plate and dash anchor together and tighten it down once you've found a level position with a clear view over the dash.

All that's left is to power it up. I chose the simple route of running it to the 12V location under the center display area. It is switchable, such that it will turn off the radar detector when you exit the vehicle and automatically come back on when you get in. As we learned with Tesla this is subject to change with OTA updates but as of June 2023 this is true.

With this installation method you can choose to leave the radar installed all the time, swap out the accessory by loosening the socket arm, or remove the entire thing with a Philips screwdriver to the dash anchor.

Simple. Too bad for the folks that don't have the 12v under the dash though....

Anyone have any input on if the 12v under dash (and in frunk) has returned with recent build VIN's?

 

[dgennetten]

What phone mount do you have there?

Thanks for sharing. I swap the Uniden R4 from my Plaid (hardwired) to Rivian (double suction cup/12v cord). If I went this route for the Rivian, I would be "stuck" seeing the unsightly ball mount glued to the bottom of the detector when it was in the Plaid. Pass.

Got my R1T less then 30 days ago. Not a 12v to be found outside the gear tunnel.... I'm trying to figure out how to install a dashcam without taping wires etc. Idk why someone thought removing the 12v from under the dash was a good idea.

I believe these will work on our trucks:

Anyone on this thread able to confirm?

Of course, Amazon now lists it as out of stock... ?‍

There are a couple options for ODB-II based power:

1. Scosche Universal 5ft USB Hard Wire Kit with 18W USB-A QC 3.0 Port
2. Garmin Constant Power Cable

The Scosche part has a pass-through ODB-II plug design, but the Garmin does not. This means that you could plug the Garmin into the Scosche, and then plug the Scosche into the R1's ODB-II connector and get 3 USB connections, one of which is QC3.0-compatible (Scosche), and the other two (Garmin) which can be programmed to stay on for 10 minutes, 24 hours or forever. It does have low-voltage detection as well.

I bought these 2 days ago, so I assume they're still in stock at the 'Zon.

Thanks. What's your VIN (approximately)?

Looks like 19084

I just checked with my guide and he seems to think the removal of these 12v plugs is a permanent decision at this point. He says there has been no communication about them coming back.

Bummer. I'm going to have to figure out how to wire one myself.

Everyone has their own situation, glad to hear yours is working. There are many ways to mount a radar, this is one.

I did get one of these mounts in 1" variety for a phone mount and have been disappointed with how much movement it still allows no matter how much you tighten the screw. With the square profile in the main body of the arm it just doesn't seem to fill the space well and wobbles up and down over bumps.

Also, newer Rivians lack the 12V under the dash. For my phone mount I had to drag a wire all the way from the center console bin USB-C ports.

Sorry to hear that! Did you contact our customer support to make sure there's not something else going on? That does sound abnormal compared to ours and many other users.
