iNavX can request, download and display GRIB weather forecasts.
GRIB are output files generated by computer forecasting models. They are tremendously more compact than regular weather charts and because of their size are very well suited for download via wireless means. The largest producer of GRIB weather is NOAA although other organizations such as the military and research institutions also generate GRIB files. NOAA GRIB files are the best ones suited for marine forecasts.
GRIB files can come into iNavX three ways: X-Traverse or Email or iTunes:
Via X-Traverse
1) From the iNavX main menu, select "Setup".
2) Select "X-Traverse Account".
3) Enter email address used for X-Traverse account and X-Traverse password. Note if you forgot them, then reset password..
