Check out the one I posted above from Course. In a perfect world, it's a Magsafe Iphone mount that is to the left of the screen, about where the gear shifter buttons are. Just to the right of line of site would be ideal. Here is the mount in my Jeep Wrangler; it's in an ideal location. That's a magsafe mount from Journey, which we have used offroading with zero issues (it has a ball mount on back). See
HERE. (Please don't judge my wiring in the Jeep; I am in the process of installing two 12v USB-C ports facing up in the front dash tray so that the two phone mounts and the radar detector will have zero cords hanging down the dash)
BTW, these mounts would never fly in the Denali. This is one of those "Jeep Things" that no one understands... it almost looks like we taped a VCR up on the dash, ha! In the Denali, we are looking for extremely clean like the Course mount!
