We have just had the Sirius Weather module added to our C-80 display. A few thuings to note for any one thinking about this investment. Last week we ran with a storm approching. The Weather data was great and we timmed our trip to a tee. The info is accurate and great to watch as a weather buff. We enjoy the fact you can jog to any location in the states and check the weather from waves to sea temp. The animation feature allows you to view the storm building and add storm tracking to see its heading and speed. The down side is it does not show much more than the shore line. I guess what I'm trying to say is it is void of hi ways and cities. It would be nice to use those as reference points. Other than that it has become a great resouce before durring and after out trips.
Hope this helps!
