The OpenSourceEV NextGen Phone Mount V2 is the latest generation of the best phone mount on the market for Rivian R1T and R1S. This updated version of our mount that installs at the very top of the passenger side outboard vents. It doesn't obstruct airflow at all, it's easily in reach of the driver, and it's outside of the shadow of the steering wheel.
Included balls at every size are now have a slimmer base, so that the installed mount is now able to adjust nearly 20 degrees further. This allow even more flexibility in phone positioning to better dial in ergonomics.
The NextGen Phone Mount V2 has been painstakingly updated to make this the very best phone mount on the market for the Rivian R1T and R1S. Here's what's new:
The NextGen Phone Mount V2 continues the precedents set by the last generation phone mounts we released. We wholeheartedly believe it's the absolute BEST phone mount on the market for the Rivian because:
The NextGen Phone Mount is compatible with all three ball sizes - 17MM, 20MM and 1 Inch. The 17MM works with most phone mounts, 20MM works with the co-branded Offroam x Peak Designs products, and a 1" size designed for RAM branded items only.
If you're not sure what to get, we recommend the 17MM setup. It's what most phone holders on the market use, for better or worse. This includes all four options that we sell, should you not want to roll-your-own.
This mount alone will not hold a phone in your Rivian - it is designed to be an attachment for a 3rd party phone holder. The phone holder snaps onto the ball mount and locks down in place via a locking screw on the back.
We sell two different phone mounts that we have validated to worked exceptionally well with this mount. We're not bundling in either of the powered mounts from the driver side as there is no easily accessible power on the passenger side.
Pictures of each mount are in the gallery - both of the part, and what it looks like installed. As each mount is magnetic, they all come with a metal ring that can be affixed to your phone or case if not equipped already.
This video was produced for the V1 unit. An updated video is coming soon.
Customers praised this phone mount for its low-profile design and secure hold. Shoppers said it's "perfect" and "holds my phone securely." The product received positive feedback for its effectiveness and minimal footprint, making it ideal for passenger-side installation.
I got both the driver and passenger side ones. Well made and works great for my husband's pixel 8 and my pixel 6 XL.
This is perfect. Low profile and holds my phone securely!
This is an update to the review I left on 11/15/2025. As Rob stated I his response they shipped me a known good ball and this has no issues at all. I am impressed when a small company follows up like this.
Not sure when there was a redesign, but the one I got today has a screw and barely makes it out of the first ball section. Not a huge deal just need to find a longer one.
Hi Sean - Thanks for the review. This is likely due to the ball and the base not quite lining up 100%. If it's not aligned and seated correctly, the bolt would appear to be a smidge too short. There may be a slight defect with this mount if that isn't the case - reach out via the Contact Us link and we'll send over a replacement to get this sorted for you. --Rob
Does the job and seems generally well made. I took one star off because the 3D printed ball was either slightly too large or slightly misshapen and I had to file it down for it to fit it the socket on the MagSafe charger. I still commend this company for providing these thoughtfully designed accessories.
Hi Tom - We looked at all of the 17MM balls that we had in stock and tried them with the mounts that we sell, and you're right - there was an unexpected change in the balls where they had supports to print on the bed. We're thinking this might be due to a 3D printer slicer updated, and it's indeed problematic with one of the Lisen phone mounts.
We've tossed the lot and have printed more with the correct supports, and the issue appears to be solved. If you would like a known-good replacement, just reach out via the Contact Us page. --Rob
I am really happy with this phone mount. Its nice to get something that doesnt cost $50 or more. There aren't many that fits the driver door side that allows for clear vision.
In order to install this properly, I had to shorten the screw by 4mm and then superglue the nut into the slot where it goes - first attempts to install this with the too long screw resulted in the nut stripping the slot so it kept turning without tightening. Once installed with the shortened screw and nut glued in, it works well.
Hi Robert - Thanks for the feedback. We don't carry a screw that is too long for this application, so something may have gone wrong during install. Can you reach out to us so we can replace the broken parts? --Rob @OSEV
Fits as described and places my phone off to the left out of the way of the screens. Be sure to hand tighten, install the mag phone mount, remove the mount then hand tighten again. It will seat itself as you do this. Might want to check the tightness after a few weeks just be sure not to over tighten, just good and snug. Love the product! Well built.
Great product - perfect fit!
Had a fitment issue. Communication was great. Resolution was perfect. Works great!!!!!
Very simple to install but it's rock solid. Paired this with the Offroam + Peak Design MagSafe charger. Now I have a perfect view of my phone, unlike the mount I tried before which was next to the main display where my phone was mostly obscured by the steering wheel. Much happier with this one and its location.
I previously had purchased the left hand drivers side mount they made. I installed it and it never really fit right where it was supposed to against the A pillar. It’s worked for almost a year but had recently been more problematic. So,I saw that they had improved that design and decided to give it a go. I’ve installed it and it is by far a better fit design. It holds the phone mount snugly and should continue to do so indefinitely. Very glad I made the swap.
This mount is exactly what I was looking for. Secure and unobtrusive. Much safer than glancing down at the phone on the charging pad. I bought the kit with the Lisen holder and it works great. Also got one for the passenger side and my wife loves it.
perfect!
This was super fast and easy to install and securely holds my phone charger/holder.
It liked the design. The ball mount could have little bit stronger but still it fulfills my requirement.
Got the left side (drivers side) version and I love it. Install is pretty straightforward, just be careful not to break the tabs on the ball mount. I paired mine with Lisen MagSafe phone mount. Great combo, highly recommend!
Great design - compact and looks like an OEM add on. Easy to install, and sits out of the way, but with good visibility of the phone - left of the steering wheel.
Thanks for the review! These are currently on national backorder. More are due in toward the end of March, 2024.
I like it. Easy to install. Though ac vent location makes the phone very cold-which for an iPhone is probably much better than hot.
