Yeah, my internal battery died on the 478, meaning that it won't remember what time it is for more than about two hours powered off. This causes it to go into AutoLocate mode every time I boot it up...kind of a hassle as this is a 3-5 minute process before it knows when and where it is. I'm guessing it's just a button battery clipped in the main board, but I don't want to take it apart for fear of ruining the water seal.
