Query: Great, but you need to know...

Please note the the angle of the arm is 90degrees, which is clear in the photos. The one on the section cup one is about 45. I had bought to mount on my motorcycle for a Garmin Nuvi 225, but the head restricts swivel too much so I can't turn up enough to see. The 45 would have been perfect. Consider where you are mounting before purchasing. A standard top of dash horizontal location should be fine. The quick release and locking base swivel seems well designed.
