This doc is nicely designed. The phone clips into place easily and charges very quickly. The glass suction mount holds seemingly forever. There is just a single cable and at the power-connector end is also an audio connection so there is no need to route an audio cable to the dock separately. Nice. The power connector also has a spare USB connector to charge a second device from.
Overall this is a nice tool that makes the navigation utility quite useful and provides a sensible interface for use in a car.
