I absolutely love this!!! I had to return a previously purchased car phone holder but this is perfect! If I could buy one for my family and friends, I would!! The quality is top notch, it moves smoothly and was a super easy install!!

Works

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
Color: for X3 2018-2021，X4 2019-2021【10.3 inch Screen】
Can’t move the phone to horizontal, only vertical. I sent it back because of this.
