Just picked up this new mounting solution. Was a little skeptical but it works great. It's easily movable and should work on any car. Drove around with it today and it hangs tough; does not move.

This is what my phone is hanging on to. A small magnet the clips on the the vent.
Here's a close up. The head turns to open and close the grip. Just need to connect a small magnet to the back of your phone.
Magnet does not interfere with the operations of the phone. I also have a case on mine so the magnet is not directly attached to my phone. Comes with 3 different size magnets. I am using the smallest one and again doesn't move. Picked this up for about $25. Overall I am very happy with this solution.
