EVO Phone Mount V4.5 for Rivian R1S & R1T

The OpenSourceEV Parts EVO Phone Mount V4.5 is the fourth generation of the most popular inboard phone mount for the Rivian R1S and R1T. It tucks between the gauge cluster and infotainment screen, installs in seconds without tools, and holds securely via friction. Manufactured and supported by OpenSourceEV, tested in Rivian vehicles, and built for daily use and road trips alike.

Choose the mount only and pair it with a ball-compatible holder you already own, or add one of five name-brand MagSafe phone holders at checkout. If you want maximum flexibility, the All + Upgrade Kit option includes every ball size and the parts needed to convert this mount into a NextGen Phone Mount V2.5 -- and vice versa.

What Makes This Different

  • Proven Design, Continuously Refined: Four generations of community feedback and real-world Rivian use. The contact area with the infotainment screen was increased 35% in V4 for a tighter, more secure fit.
  • Dual Function: An integrated loop on the mount doubles as a sunglasses holder even if your phone is on the mount.
  • Modular Ball Mount: The ball is a separate, swappable component. Change holders or replace a broken ball without replacing the entire mount. Available in 17mm, 20mm, and 1-inch sizes, or purchase all sizes in one kit.
  • Secured by Steel: An M5 x 35mm stainless steel bolt and nut holds everything in place. Competing mounts rely on clips, which are significantly more prone to failure.
  • Textured Ball: The mounting ball has a textured surface that allows phone holders to grip significantly better with less clamping pressure. Other mounts slip.
  • Extended Range of Motion: New in V4.5, a slimmer ball base allows nearly 20 degrees of additional adjustment for better phone positioning and ergonomics.
  • ASA Construction: Printed from ASA for superior UV resistance and temperature resilience up to 300 degrees F. Competing mounts use PETG, which can deform in heat, or ABS, which fades with UV exposure.
  • Open Source Design: Design files are publicly available under Creative Commons NC-SA 4.0 for personal use and remix.

Ball Size Guide

The EVO Phone Mount is available in three ball sizes. The 17mm size works with the vast majority of phone holders on the market, including all five holders we sell. The 20mm size is compatible with Offroam x Peak Design co-branded products. The 1-inch size is designed for RAM-branded accessories only. If you're unsure, choose 17mm.

Available Phone Holders

This mount requires a separate ball-compatible phone holder. The holder snaps onto the ball and locks via a screw on the back. Five name-brand holders are available to add at checkout:

  • OSEV Offset Charging MagSafe: OpenSourceEV's own MagSafe holder. Offset to keep your phone clear of the vent airflow. Open center design. Dim blue LED ring for targeting at night. Uses less than 1mw when not charging -- no impact on the 12V battery. Available in 17mm only.
  • ATB 720 Degree MagSafe: MagSafe holder with a secondary adjustment screw midway along the arm for the most positioning flexibility of any holder we carry.
  • Lisen Offset MagSafe: MagSafe holder offset to keep your phone clear of the vent airflow. Open center design.
  • Lisen Charging MagSafe: Charging MagSafe holder. Charges fast with minimal heat. Near-invisible blue LED ring for targeting at night. Uses less than 1mw when not charging.
  • Lisen Charging and Cooling MagSafe: Charging MagSafe holder with a built-in cooling fan. Nearly inaudible when running. Small yellow LED indicator. Uses less than 1mw when not charging.

All magnetic holders include a metal ring for phones or cases without built-in MagSafe. Charging holders include a USB-A to USB-C cable.

Key Features

  • Installs between the gauge cluster and infotainment screen. No tools, no bolts, no adhesives.
  • Secured by an M5 x 35mm stainless steel bolt and nut.
  • Integrated sunglasses loop that is usable regardless of the phone being installed.
  • Printed from ASA for superior UV resistance and temperature resilience up to 300 degrees F.
  • Manufactured, sold, and warranty-supported by OpenSourceEV Parts. Made in the USA.
  • Fits Rivian R1S and R1T.

Using a Charging Holder

Charging holders require a USB-A power source. The Scosche OBD-II to USB-A Quick Charge Connector is available as a bundle and is the recommended solution. It plugs into the OBD-II port in the driver footwell, includes an OBD-II passthrough so the port stays accessible, is fused inline, and has a cable long enough to route cleanly under the steering column without running behind trim or weather stripping.

Installation

  1. Insert the included nut into mount and thread the stainless steel bolt through the ball and mount body.
  2. Tighten the bolt until snug -- it just needs to not rotate.
  3. Slide the mount into the gap between the gauge cluster and infotainment screen until it seats firmly.
  4. Remove the locking screw from your selected phone holder and slip it over the ball.
  5. Snap your phone holder onto the ball mount and lock it down via the holder's locking screw. Again, don't over-tighten as the textured surface should bite well.

Customers praised this vehicle-specific mount for its easy installation, discrete placement, and secure phone positioning. Many noted "excellent customer support" and "great customer service." While most found it sturdy with minimal bounce, some reported durability issues including breaking, melting in heat, and loose ball attachments. A few mentioned it blocks screen controls. Overall, shoppers appreciate the design improvement.

One minor tweak and it's now perfect.

I tried many different phone mounts for my R1S and they all had their strong points. One thing that they also had in common ... my phone jiggled while I was driving. It was worse on the mounts with longer arms (that's just physics). I settled on this mount, with the cooling Lisen MagSafe charger, after making one little tweak. I added some double stick tape to adhere it to the center display ... I used the thin "LCD repair tape" used inside cellphones and other electronics, because the 3M stuff is too thick and too strong. Adding that adhesion so close to the ball mount has totally eliminated the shakes when the phone is mounted. FINALLY.

Replaced my original Phone Mount PRO

I replaced my original Phone Mount PRO from Opensource EV (Riviparts) with the newer EVO model and it's night and day. My phone was previously hidden behind my steering wheel despite an attachment I purchased on eBay to make it rise up a little. This new EVO model resolves it so that I can see the screen completely now!

Works well and excellent customer support

I enjoyed the first gen version for three years and found it was the best product on the market with a convenient placement that was discrete looking and worked well. This next gen version is even better. And the customer service from owner Rob has always been A+. Highly recommend.

Excellent mount

Excallend mount, easy to install, not much bounce on rougher roads.

Almost there

The base piece clicks in to the dash really well. But, (1) the 17mm ‘ball’ didn’t fit my mount and I had to seemed it to make it work (2) the ball part doesn’t attach securely to the base… those tabs are too small and the supplied nut spins in the slot so the entire ball attachment wiggles. (3) the final position of the phone doesn’t work, blocks too much of the left side of the center screen.
I’m happy to support this maker community but this part didn’t work for me

Hi Stephane - Thanks for the feedback. Something doesn't seem quite right here - it might be an issue with that particular print or something similar. Can you reach out to us via the contact form with what you're seeing? I'd like to attempt to correct this for you, if you willing.

Sorry, but nope!

3D printed part is weak. It broke immediately. I didn't have the energy to request a replacement. I just bought another product that is working perfectly.

Hi Gil - Thanks for the feedback; that is very much not supposed to happen. We're happy to replace the item for you if you do find the energy to reach out. It's quick to do so, just use the contact us link at the bottom of each page.

Good Holder

Great holder, worked well. This is my second purchase first one snapped in half after 1 year. Otherwise great product, especially for the low cost.

Great product from a great company!

I bought the original phone mount and it worked well but come summer, the plastic melted. The company stands behind their product and replaced it with an updated design that is even better than the original, easy to see and easier to adjust. Pleasure to do business with Open Source EV

Love it!!

It’s so much sturdier than having the swivel arm attached like the previous one. It’s in a great location and very stable! No more vibrating phone. So simple!

Excellent upgrade

Open source replaced the previous model (it would melt/sag in the sun) with this new model. It is sturdier, and locates the phone to the right and up, out of the visual path of the steering wheel. Impressed with standing behind their products and making the situation right. Refreshing to deal with a reputable company. Thanks

Melts in hot temperatures

Worked great until the summer weather then melted on a hot day when cabin temperatures were high when parked in the sun.

Hi WP - Looking at your order history, it appears that you just placed an order for the EVO mount and it hasn't even arrived to you yet. You may be referring an older, OG Phone Mount that you purchased in 2022. We have a special program on mounts from that era that were contract manufactured for us. We're replacing them, for free, even two years later, as a small percentage may exibit the behavior that you mentioned. Please reach out to us via the Contact Us page below. There are details about the program there, and we're happy to help.

Great product and great customer service

Had previously purchases a different mount, similar in function as this one. But I think the product had some weak points that caused it to snap off. sent an email to the customer contact and Rob immediately responded and discussed the issue and offered a replacement of the same item or this EVO Mount. Opted for this for the reason I see it has the extra strength of the screw. The product is perfect and easy to install. Overall rate them best for the commitment to the customer. Thank you Rob.

Works great until Apple CarPlay (if ever)

Easy installation that looks great. Very stable for iPhone 14. Fast shipping! Thanks!

This the one you want

Especially for heads up navigation. Perfect and secure placement and ease of use. I prefer to charge with a cable so the AINOPE phone holder that works with this and is mentioned in the description above is perfect! My only ding would be having to reach around my phone to lock/unlock the vehicle on the main screen. Well worth the minor inconvenience to have my phone in the perfect spot and be able to grab it and go quickly. 10/10 recommend this simple and easy to install product!

Awesome phone mount

Exactly what I was looking for. Added my own phone holder and am a happy camper. Thank you for creating such a simple and useful accessory.

works great

Easy to install and when paired with a magnetic phone mount I purchased from Amazon I can mount my phone without the steering wheel blocking my view.

Best phone mount I've been able to find for the R1S

second mount working

First mount broke because I pressed the wrong area (because i thought the pressure fitting would scratch the Rivian touch screen frame). The second one installed correctly, but in my effort to secure the ball while fiddling with the Spigen phone mount, i overtightened and snapped the plastic pins on the backside that prevent the ball from spinning. The ball is a bit too close to the screen and it is very difficult to mount a the phone holder - not enough for the threaded collar to be adjusted properly. However, it is in place and functioning reasonably well. The mount has some play but so far has not affected the performance - as in the phone does not shake too much or move out of position.

Hi JJC - Thanks for the review. Please reach out to use using the Contact Us page, we'll replace the ball for you.

Regarding installing, we've purposefully located the ball close to the screen. We recommend tilting the phone holder you install on it all the way to the left to give yourself enough clearance to tighten it down correctly. (e.g. face it roughtly toward the drivers window) Feedback that we've recieved is that works nearly every time.

Right Side Rivian Phone Mount Works Perfectly!

The mount snaps in easily and positions the phone where I can see it without blocking the screen or being hidden behind the steering wheel. Very sturdy and doesn't move around.

Best phone mount for RIVIAN R1S!

I tried several other options and none worked well until the Evo mount. I paired with the Lisen mag safe unit for my iPhone 14 Pro and it looks as if it was OEM - perfectly matching with the RIVIAN dash. Is great!!

Sleek and Elegant

I really enjoy the phone mount I added the Seigen wireless magsafe mount to it. Modern contemporary look hardly noticeable. The mount looks like it should have been there from the manufacturer.

Great concept but…This is the second one I bought First one broke second comes apart all the time

Hi Mark - Can you please reach out about what you've reported here? I'm not seeing that you have multiple of these, and I'd like to understand what is happening here and make it right. - Rob @ OpenSourceEV

Really ingenious design, everything fits together perfectly. Mount fits snugly between console and dash, and holds a phone in the perfect position. Great product and great service!

Nice Fit - Quality - Great Design

I have had both ball mounts, I bought this to see if I could get rid of an extension on the first one to move my phone up from behind the steering wheel. This one is a tighter fit than the original, and I was able to get rid of that extension. Honestly I wish it was about 1 inch higher, but I can probably accomplish that with whatever phone mount I use in front of it.
