The OpenSourceEV Phone Ball Mount EVO is the third generation of the best phone mount on the market for the Rivian R1S and R1T. It's designed to tuck in between the gauge cluster and infotainment screen. It's held in place via friction and is easily removable.

The Phone Ball Mount EVO improves on the Phone Ball Mount PRO in the following ways:

  1. The ball mounting location is moved upward, to the right, and slightly forward for a better viewing angle which is less obscured by the steering wheel.
  2. The surface area along the rear of the infotainment screen is significantly larger to ensure a tighter, more secure fit.
  3. The ball mount is now modular, allowing for a quick swap between sizes without having to purchase a brand new mount and without having to deinstall the base.
  4. The ball is now secured in place by an M5 x 30MM steel bolt and nut which better supports larger, heavier phones.

The Phone Ball Mount EVO is compatible with all three ball sizes - 17MM, 20MM and 1 Inch. One of these is included, other are sold separately. The 17MM works with most phone mounts, 20MM works with the co-branded Offroam x Peak Designs products (link below), and a 1" size designed for RAM branded items only.

Please note that this mount alone will not hold a phone in your Rivian - it is designed to be an attachment for a 3rd party phone holder. Phone holders pictured are not included. We suggest defaulting to the 17MM mount unless you know exactly what you want. We've also tested and suggest the following phone holders that are known to work well with this mount:

** Please note that Phone Mount PRO and extra ball sizes pictured are not included **

Works well

Easy to install and holds my phone well. Great product.

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

great product

great product, best accessory for the rivians

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.
