I thought sticking my old phone in the built-in dash pocket worked well, but the ProClip mount is worlds better.

The phone is up higher now and the bottom of the phone isn't obscured by the pocket so it's easier to see and use.  Using the face ID on the iPhone XS works great in the mount too... all I have to do is move my head slightly to the right and the phone unlocks.

The mount is sturdy enough you can type on the phone with it in the mount and it's rock solid.

It's unusual for me to endorse a product like this, but I think it's really well designed and I was surprised to find something made specifically for the Transit dash.
