Works
Color: for X3 2022-2024，X4 2022-2025【12.3 inch Screen】, Color: for X3 2022-2024，X4 2022-2025【12.3 inch Screen】
It fits with my BMW X3 2022. It also has a back pocket that offers storage behind the screen. I wish it had a magnetic holder but that has nothing to do with this product.

Fits great minus no horizontal view

Can’t move the phone to horizontal, only vertical. I sent it back because of this.

The fit is perfect and is a sold mounting system
Custom fit for 2022 Tacoma, fit exactly. Very sturdy mount and took seconds to install. All metal with the exception of a adjustment knob. Quality hardware. More expensive than a lot of mounts but most are cheap plastic and are not nearly as solid and sturdy as the Offroam.
