Radar Detector Mount Setup for Rivian R1T / R1S - Quick, Easy, and Rem – 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 (paid link) but there are many other great detectors out there for your choosing.

Parts Needed

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

3" Socket Arm (25mm/1in/B-Size) (paid link)

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

Think of these items as Lego. There are 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.

UPDATE: In early 2023 Rivian removed the 12V ports both under the main display and the frunk. Alternatively you'll want to source power from the fuse box in the footwell or use an OBD2 to 12V adapter, though not switchable.

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.
