I'm trying to decide among products and was wondering what the source of the weather info for Nav Pro is. How often is the update? How does one receive the updates, internet? Does the weather overlay on the actual chart? Does XM Satellite Weather work? Lots of questions!!!
Chart Navigator Pro gets it's weather dat from NOAA.
GRIB files can be brought into CNP from other sources, by clicking on the Open folder in the Graphical weather forecast panel and browsing to GRIB files saved to the hard drive.
I just want to make sure I understand the GRIB files overlay function. I can download grib files over my email account and overlay them over the charts. As I am voyaging, I am not going to have access to the Internet, but I will be able to download GRIB files via SSB radio and my sail mail account.
