This is far from the first time we are hearing about a car dock for the Nexus One, but this is the first time that it has been pictured. That and, perhaps more importantly that dock is now available for purchase. And its probably hard to argue that this dock combined with the Google Maps Navigation app (on updated Android phones) will make a nice combination. Anyway, as of now you can head on over to the Nexus One Store with Google and purchase a dock of your very own. The purchase price — $55. In addition to holding your Nexus One and attaching it to the windshield, the dock is also touting features such as built-in speaker, built-in Bluetooth, quick access to voice commands and the ability to charge your Nexus One battery.
