This time last year, Google added new functionality to Maps on Android phones - Google Navigation. The new feature allowed you to search for directions as per usual, but then take it a step further and switch the results into turn by turn navigation. I’ve long resisted the SatNav world, although I have no real reason why. Perhaps I couldn’t justify the cost in my head, and didn’t particularly want another gadget, although I don’t recall putting even that much thought into it.
