FCC Statement
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a normal installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio
or television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an output on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced technician for help.
A shielded cable must be used when connecting a peripheral to the serial ports.
Important
The choice, location, angle and installation
of the instrument & transducers are critical to
performance of the system as intended. Follow
instructions in this manual carefully. If in doubt,
consult your Northstar dealer.
Ensure that any holes cut are in a safe position and
will not weaken the boat’s structure. If in doubt,
consult a qualified boat builder.
Do not install plastic through hull transducers in
solid wooden hulls. Leaking through the hull may
result.
Do not install bronze transducers in metal hulls.
This will cause electrolytic corrosion that may
result in damage to the hull or transducer.
Sonar Performance: The accuracy of the sonar
depth display can be affected by many factors,
including the type and location of the transducer
and water conditions. Ensure that the transducer is
located and used correctly.
Global Positioning System: The Global
Positioning System (GPS) is operated by the
US Government which is solely responsible for
its operation, accuracy and maintenance. The
GPS system is subject to changes which could
affect the accuracy and performance of all GPS
equipment anywhere in the world including
the 657. Whilst the Northstar 657 is a precision
navigation instrument, it can be misused or
misinterpreted, which can result in its use
being unsafe. To reduce the risk of misusing or
misinterpreting the 657, the user must read and
understand all aspects of this Installation and
Operation manual. We also suggest that the user
practice all operations using the built in simulator
before using the 657 at sea.
Electronic Chart: The electronic chart used by
the 657 is an aid to navigation and is designed to
supplement the use of official government charts
not replace them. Only official government charts
supplemented by notices to mariners contain
the information required for safe and prudent
navigation. Always supplement the information
provided by the 657 with other plotting sources
such as observations, depth soundings, radar and
hand compass bearings. Should the information
not agree then the discrepancy must be resolved
before proceeding any further.
Sonar fishfinder: The accuracy of the sonar
depth display can be limited by many factors,
including the type of the transducers, the location
of the transducers and water conditions. It is the
user’s responsibility to ensure the 657 transducers
are installed and used correctly.
AIS: The AIS features on this chart-plotter are
designed as a safety aid only and do not guarantee
safety at sea. AIS transmission is mandatory on
some, but not all, vessels. You should check your
local laws and regulations for requirements in your
area. As a result of different legal requirements,
different vessel sizes and uses, you should not
assume that your AIS equipped chart-plotter will
show the location of ALL vessels in your area.
Careful prudence, judgement, and safe navigation
practices should always be exercised. AIS should
be used to complement radar, but AIS is not a
substitute for radar.
Fuel Computer: Fuel economy can alter
drastically depending on the boat loading and sea
conditions. The fuel computer should not be the
sole source of information concerning available
fuel onboard and the electronic information
should be supplemented by visual or other checks
of the fuel load. This is necessary due to possible
operator induced errors such as forgetting to
reset the fuel used when filling the tank, running
the engine with the fuel computer not switched
on or other operator controlled actions that may
render the device inaccurate. Always ensure that
adequate fuel is carried onboard for the intended
trip plus a reserve to allow for unforeseen
circumstances.
Failure to adhere to these warnings may
lead to death, serious injury or property
damage. Northstar disclaims all liability for
installation or use of this product that causes
or contributes to death, injury or property
damage or that violates any law.
The 657 is set up with default units of feet, °F
(Fahrenheit), US gallons and knots. To change the
units, see section 17-10.

7Northstar Explorer 657 Installation and Operation Manual
1-1 Ov ervi ew
The Northstar 657 is a compact, rugged, highly
integrated marine chartplotter and fishfinder. It is
easy to use and has an easy to read color display.
Complex functions can be per formed with a few
key presses, taking the hard work out of boating.
The available functions, displays and setup
menus depend on the optional sensors and
instruments that are installed:
Sonar functions require a sonar transducer to
be installed
Fuel functions require one or more
petrol/gasoline or diesel fuel sensors to be
installed.
SmartCraft™ engine functions require a
SmartCraft™ system to be installed. For
information on using SmartCraft™, see the
SmartCraf t™ Gateway Installation and
Operation Manual.
1-2 Cleaning and main tenance
The 657 screen is covered by a proprietary
anti-reflection coating. To avoid damage, clean
the screen only with a damp cloth and mild

1-3 Plug-in cards
The 657 can use two kinds of plug-in card:
1 C-MAP™ chart cards have chart details
required for navigating in a particular region.
When a chart card is plugged in, the extra
details automatically appear on the 657 chart
window.
The 657 can use NT, NT+ and NT-MAX
cards. NT-MAX cards have much more chart
information than earlier cards, including
photos of points of interest.
Northstar Explorer 657 Installation and Operation Manual8
2 C-MAP™ user cards are used to store
navigation data. Each user card expands
the 657 memory and allows the data to be
transferred to another 657 easily.
(see section 14).
Note: The older 5 volt user cards are not
supported.

3-1 Introduction to navigating
The 657 has two ways of navigating, going straight
to a point or following a route.
3-1-1 Navigating to a point
When the 657 is navigating to a point, the chart
and highway displays show navigation data:
A The boat position
B The destination point marked with a circle.
C The boat’s plotted course to the destination.
D Two CDI lines, parallel to the boat’s plotted
course, which indicate the maximum
expected deviation from the plotted course.
A
For more information, see appendix C.
If the 657 is connected to an autopilot, the 657 will
send data to the autopilot to steer the boat to the
destination. Start the autopilot before starting to
navigate to the point.
If the 657 has no autopilot, steer the boat
manually:
a use the boat position and destination on the
chart or highway displays
b or use navigation data displayed on the data
header (see section 2-7-3)
c or use COG and BRG on the compass (see
section 2-7-4).
Note:
1 If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (see section 17-9).
2 If the arrival radius alarm is enabled, then an
alarm will sound to show that the boat has
reached the destination (see section 17-9).
