Phone Mount Dash Anchor for Rivian R1T and R1S

Installation was a bit difficult until I realized that the screw spreads apart the pieces to hold the mount in place. Unfortunately, I found it totally unusable due to how much the phone vibrates. I have a 2025 R1T.

This is a sturdy phone holder. I just purchased the arm with the 17mm ball and it mounts to the back of the monitor securely, no wobble. The position of the ball is really good as well, I have a charger that mounts directly on the ball, no extention arm, and my sight line to the phone is above average.

Installation was easy, and took advantage of existing elements of the vehicle for a solid and sleek mount. Really impressed with the thoughtful design. In use though with the charger and my phone on the arm it's still bouncier than I would like and I find the flashes reflecting off the phone screen distracting. It's position is also such that I can't find an angle where where my phone (OnePlus 13) is at a good angle and isn't mostly obscured by the wheel and doesn't interfere with the drive selector stalk. I've found a position that's "OK", but not great, and we'll see how it goes. I think it would be better with a smaller phone, or with a phone where the magsafe ring were positioned different. Seems like if it were a little taller it would work better for me.

Only reason I couldn't give this a 5 star is because when my phone is attached and I am driving the arm shakes causing the phone to shake a lot. Otherwise it's a great product. The longer arm could use a vibration dampener maybe.

Install was relatively easy. The number 3 slot kept trying to pop out so it had to be held from the back while tightening the screw, but overall it went great. The arm is extremely strong and doesn't wiggle which is great. It being your phone high enough to avoid the steering wheel and that is great!
