Navionics+ for US Coast and lakes, MFG# MSD/NAV+NI, includes charts detailed pre-loaded on card.
Updates can be downloaded by the customer, sonar charts and community edits free for one year.
Card reader for computer is included.
The issue with paper charts is that once you have the chart, the data you rely on never changes until a new chart is purchased.
Electronic charts offer the ability to update and add to the data available, but actually doing the update still requires buying a new chart, though usually at a reduced price.
Because of that, charts are rarely updated by people.
Navionics+ solves that issue by including unlimited updates to the basic chart data contained on your chart.
The card comes pre-loaded with charts highly detailed and is ready to use as soon as it is plugged into your plotter.
In addition, the card can be plugged into your computer (using the supplied card reader) and a wealth of additional information can be downloaded as often as you like.
Information available includes: official updates: government agencies and cartographers are constantly updating the information contained on electronic charts.
With Navionics+, those updates can be added anytime you want.
Sonar chart: sonar data from a variety of sources, including Navionics users, is collected, correlated, and added to your charts, creating detail high-definition of bottom contours.
Send in your sonar logs to help build a more accurate database for all to use.
(For compatible chartplotters) community edits: Navionics customers continually send in local information that is added to the Navionics database.
Update sonar chart data, basic chart data, or community edits for up to a year.
When your first year is complete, the service can be renewed a year at a time for a reasonable fee.
