Smash or Pass? ….Smash.
The smash phone mount did the trick. There was never a good or convenient place to put my phone in the 4-runner. This piece of kit fixed the issue nicely. Fits in the little storage spot tightly with a spring loaded friction mount. The hardware to manipulate the holder so you can customize your preference is made of metal so it will be durable and stable and bc you can change it around to fit your needs it has a lot of functionality. A little pricey but a good add-on for the rig.

Get the stubby, not the standard
This is a very nice mount. I strongly recommend the stubby version over the standard, mostly because you can move the phone holder around to help keep it visible and out of the way. As a taller guy, the standard mount would be hitting my knee when I get in the vehicle, but the stubby mount allows me to move it further towards the passenger side, which also keeps my cup holder usable.

Perfect fit attachment!
This product is built very strong and fits perfectly into the small cubby in the lower middle dash of my 2018 4Runner. It holds my iphone tightly but is easy to remove. 100% satisfied with this purchase.
