Lastly, could someone explain what is the difference between this and the zumo 550/660?
Edit: I think I answered most of my questions with the 478 thread :)
You may want a 378, it has inland waters, 478 has coastal.
South hombre, the setting sun to the right until we are out gas, cash or goddamn snow.
