There’s good chance that the Caseco Core 360 car phone holder. It may be the smallest and least obtrusive of the many mounts that I’ve checked out.
It’s a simple post with an adhesive backing that sticks to a smooth spot on your dashboard. You can place it almost anywhere that’s not leather or vinyl, keeping all of your dashboard air vents open and unobstructed.
I especially like the flexibility that the mount provides to give you the best viewing angle. You can tilt the phone up vertically or horizontally and you can rotate it to get a wide view of a GPS map.
The Core 360 comes with two rings and sells for $39.99 at the Caseco website. If the vent happens to be your preferred spot, Caseco also has a version with a vent clip.
You can see the mount in action in the video below and follow @Caseco_inc on Twitter.
