Not a lot of large/flat surfaces to stick on a good mount. The custom mount that is available kind of blocks the vents, and I've never liked that option.
So I've decided to go in a completely different direction. Since I have Apple Carplay, I bought a 1' phone cable and just plug the phone in and leave it in the "cubby" under the power port.
In theory, I should be able to "use" my phone via the touchscreen, at least for anything that I would be using it for, while driving.
