Maybe updating the firmware is why the number of icons changed (though it seems odd to me that it would go from 10 down to 6), but where is that darn Address icon? If it hadn't shown up a couple of times I'd think that it wasn't available with Recreational Lakes, but I had it there on at least two occasions, and then a minute later it was gone.
I'm looking at the Find menu, from pressing the Find button on the GPSr. The Main menu has 12 icons, and no, there aren't any more that I have to scroll up or down to.
