Navionics Differences Between Formats and Silver's Limitations
Not available to purchase on its own, Navionics Silver cartography is supplied pre-loaded in some chartplotters as an enhanced base map.
It should also be noted that the update path for Silver is to purchase a Gold or Platinum cartridge. Silver can not be updated.
Our recommendation is, if it is an option, Buy the plotter without Navionics Silver, and then Buy Navionics Gold or Platinum Plus.
Here follows a brief comparison of differences between Silver, Gold and Platiunum Plus. Silver's lack of tidal data and zoom levels alone should be enough to make the decision.
