I am a huge fan of http://proclipusa.com
car mounts! The mounts with charging capability make the need to worry about plugging and unplugging your phone every time you get in the car a thing of the past. The best part is the ability to find the right mount for your car without being forced to use suction cups which inevitably lose their suction at the worst time.
On a side note, does anyone with an S5 and ProClip mount also have the Qi back cover? It would be nice to use the Qi charger at home and the ProClip in the car.
