I was looking for a clean-looking way (relatively) to mount my phone until the Apple CarPlay/Android Auto.
After testing out a few different options, this is the mount location and the simple phone mount that works for me:
Lamicall Car Vent Mount
($10 w/ promo code LAMICV09T - Actually a wireless charger too, although I'm only using it as a mount)
The air vent hook grabs well to the back of the Clearview Cockpit plastic trim piece, and the rubber padding gives it a snug fit on the screen's bottom edge.
