maps can give you an approximate idea of your location with
respect to land areas. Nav aids are not included.
For more detailed charting data, you'll want to use Navionics'
highly detailed miniature Nav-Chart™ cartridges. Navionics is
a major producer of high-quality, high-resolution "seamless"
digital charts. The 958's usefulness is greatly enhanced with
cartridges for the areas to which you plan to navigate.
Cartridge data is the result of countless hours of converting
land-mass shapes, nav-aid names and locations, depth
contours and other information found on official paper charts
into an electronic format used by the 958. Each cartridge
includes several charts covering a specific geographic location,
typically providing zoom in and out levels ranging from a
maximum detail of 1/4 nm across the screen to an overview of
up to 256 nm across. Virtually every major port and most
popular boating areas are available on these cartridges, and
new charts are constantly being added. For details about
obtaining Navionics charts, contact your authorized Northstar
dealer.
The cartridge slot is located at the lower left-hand corner of
the 958. You can see if a cartridge is inside by opening the
cartridge access door and looking inside the slot. If the 958 is
on, press the CHART SETUP menu key to the right of the
CHART screen to display the CHART STATUS screen (the
cartridge door must be fully closed and latched to display this
information):

If a cartridge is inside, the cartridge name and date are
shown at the left of the CHART SETUP/STATUS screen
(screen at left, below).
