Talk about random gifts from the ether. British Android device owners are waking up this morning to discover their robot-themed operating system has gone and upgraded itself overnight. We've confirmed for ourselves that Google Maps Navigation -- yes, the free turn-by-turn stuff with voice directions -- has made its fully functional way across the Atlantic. This is the 4.1.1 Beta released on April 6 to US customers, but as we say, it's now working over in Blighty as well. We've tested it out on a Desire and Nexus One from HTC, with the latter offering the extra-cool option to aurally instruct your Google search bar to "navigate to" your destination. Check out the gallery below for some visual edification.
