The OpenSourceEV Parts Seat Back Tablet / Phone Mount V2 for the Rivian R1S and R1T is our second version of the unobtrusive, easy to install / remove, way for you to mount a tablet or phone holder on the back of your front seat. The mount assembles quickly with one Phillips head screw and a specialized low-profile T-nut. Installation is simple and toolless as it just hangs securely on the hook mounted on the rear of the R1S and R1T front seat.

This second version improves upon V1 in the following ways:

  • Fitment is significantly more snug --The portion of the mount around the seat back hook was completely refactored to be as tight as possible without damaging the seat finish.
  • Easier install with USB-C cable -- The cutout for the USB-C cable has been expanded to allow for quick install with cables that have a more chunky connector.
  • More durable -- The curvature around the hook has been improved to carry heavier loads.
  • Better bolt / nut fit -- The depth of the bolt receptacle has been tweaked so it is more flush with both the back of the mount and to ensure the bolt doesn't poke out beyond it.

Please note that this mount alone will not hold a phone or table in your Rivian - it is designed to be an attachment for a 3rd party holder. We suggest the OpenSource EV Parts Tablet Holder for tablets with up to an 11" screen. (8" across narrowest side) we also have extensively tested with the Lamicall Car Tablet Holder - Black / Yellow - the included mount can be discarded.

Please note: When assembling, the screw should not be overtightened - it should only be snug. We recommend these to be uninstalled when not in use - they can be easily stored in the rear door pocket. Holders and tablets pictured are not included.

love the product but...........

I use the product all the time but since there is no way to Secure it vertically it does move up and down

Hi General - This product shoud be very snug and not move when it's installed. If it is moving for you, please reach out to us via the Contact Us page so we can get it fixed for you.

Does the job; keeps clear of USB port

Low-profile hook interface fits snugly over the Rivian's front-row seat-backs. The v2 changes are very snug, so be gentle when pushing it firmly onto the seat hook. It does feel a bit cheap, so I wouldn't be inserting and removing it all the time for fear of breaking it. I didn't notice any damage to the seats, just a slight scuff if I really looked close that cleaned off with a finger-rub. Pretty happy with the solution overall when combined with the tablet holder from Amazon (which, by the way, is great for the R1S 3rd-row seats).

Misleading Description

I was expecting a tablet mount (like what's pictured), but instead got a hanger with a ball on it. The product page is deceptive, and funny enough, I didn't even see there was a second piece to order until coming to write this review. Why not sell an actual "Tablet Mount" vs selling a universal ball adapter, which is what this is. It's a nice ball mount so it at least deserves half the stars.
