Looking for a weather solution for the wife’s boat

Looking for suggestions. I need an inexpensive weather device that will support an XM Nexrad service similar to what I have on the airplanes (Garmin 496). Most of the similar garmin units are discontinued.

Want something that will mount on the boats control console (it is reasonably dry there), and costs less than $600 buck. I’ll go higher if I need to, but this the price point where I won’t throw a tantrum if it falls overboard.

We have moved out boat to the top of the bay – sorry I’m aeronautical and non-nautical. It is far enough away that two storms caught us before we got back to base last year. One of them was amazing and also terrifying, even though we made in into our slip just as it unleashed and road it out there. I now fly with that added perspective.

Please shoot me an email if you have any thoughts… droid apps, whatever. I think a low end iPad would be overkill…. and I also think it would not hold up to that environment. What do you think>
