SeaDation - Yes I have it activated and it really makes it nice to know where a cell is and which way it is moving. We were coming back to the dock the other day and saw a storm in front of us, all we had to do was look at the screen to tell that it was moving sideways to us and wouldn't be a factor. Is it worth $50.00 a month?

time will tell but it makes me alot more comfortable with all the storms that pop up from nowhere.
