Warning
It is your sole responsibility to install and use the instrument and transducer(s) in a manner that will not cause accidents, personal injury or property damage. Always observe safe boating practices.
The choice, location, and installation of transducers and other components of the system are critical to the performance of the system as intended. If in doubt, consult your Navman dealer.
To reduce the risk of misusing or misinterpreting this instrument, you must read and understand all aspects of this Installation and Operation Manual. We also recommend that you practice all operations using the built-in simulator before using this instrument at sea.
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 is subject to changes which could affect the accuracy and performance of all GPS equipment anywhere in the world, including this instrument.
Electronic Chart: The electronic chart used by this instrument is an aid to navigation designed to supplement, not replace, official government charts. Only official government charts supplemented by notices to mariners contain the information required for safe and prudent navigation. Always supplement the electronic information provided by this instrument with other plotting sources such as observations, depth soundings, radar and hand compass bearings. Should the information not agree, the discrepancy must be resolved before proceeding any further.
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. Never use this instrument to gauge depth or other conditions for swimming or diving.
Fuel data: Do not rely on this instrument as the sole source of information about fuel available onboard. You must supplement this instrument’s fuel data with visual or other checks of the fuel available. This is necessary because possible operator errors, such as forgetting to reset the fuel used when filling the tank or running the engine with this instrument not switched on, can render this instrument inaccurate. Fuel economy can change drastically depending on boat loading and sea conditions. Always carry adequate fuel onboard for the intended trip, plus a reserve to allow for unforeseen circumstances.
Simulate mode: Never have simulate mode on when you are navigating on the water.
Failure to adhere to these warnings may lead to death, serious injury or property damage. Navman 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.

1-2 Cleaning and maintenance
The Instrument screen is covered by a proprietary anti-reflection coating. To avoid damage, clean the screen only with a damp cloth and mild detergent when dirty or covered in sea salt. Avoid abrasive cleaners, petrol or other solvents. If a plug-in card gets dirty or wet, clean it with a damp cloth or mild detergent.
Cover or remove a transom-mounted transducer when repainting the hull. If painting over a through hull transducer with antifouling paint, use only one coat of paint. Remove the previous coat of antifouling paint by sanding it lightly.
To optimize performance, avoid walking on or jamming cables and connectors. Keep the transducer free of weed, paint and debris. Do not use a high pressure water blast on a speed sensor paddlewheel as it may damage the bearings.
Push the dust cover over the display when the Instrument is turned off.
The NAVMAN 8120 is a rugged, highly integrated marine chartplotter and fishfinder. It is easy to use and has a very large, easy to read and use colour display. Complex functions can be performed with only a few key presses, taking the hard work out of boating.
The available functions depend on the optional sensors and instruments that are installed:
The Video window requires the 8120 to
receive video from a compatible source, such as a camera.
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 SmartCraft Gateway Installation and Operation Manual.
1-1 Overview
DSC/Buddy track functions require an
appropriate Navman DSC VHF radio to be installed.
The 8120 can send data to other
instruments, such as an autopilot, and receive data from other instruments.
For information on installation options, see section 18-2.
This manual describes how to install and operate the 8120. Special terms are explained in Appendix C. For more information on this instrument and other Navman products, go to our website, www.navman.com.
8120 Installation and Operation Manual7
1-3 Plug-in cards
The 8120 can use two kinds of C-MAP™ SD-Card plug-in cards:
Chart cards have chart details required
for navigating in a particular region. When you insert a chart card, the extra details automatically appear on the Chart window. You can plug in up to two chart cards at once. If the chart shows a region not covered by a chart card, then it displays a simplified built-in world chart.
User cards store navigation data. A
user card allows navigation data to be transferred to another compatible instrument (see section 14).
Removing a plug-in card
Turn the 8120 off (see section 2-2). Open the card cover on the right of the display.
Inserting a plug-in card
Push the card down until it releases and can pop up.
Lift the card out. Put the card in its case.
Hold the new card with the gold contacts on the far side.
Push the card into an empty socket until it clicks.
Close the card cover. Turn the 8120 on (see section 2-2).

3-1 Introduction to navigating
The chart window shows the chart, the boat’s position course and navigation data.
The Instrument has two ways of navigating, going straight to a point or following a route.
3-1-1 Navigating to a point
When the Instrument is navigating to a point, the chart and highway windows 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.
For more information, see appendix C.
If the Instrument is connected to an autopilot, the Instrument 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 Instrument has no autopilot, steer the boat manually:
a use the boat position and destination on
the chart or highway windows
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 17-8).
2 If the arrival radius alarm is enabled, then
an alarm will sound to show that the boat has reached the destination (see section 17-8).
3 When the destination is reached an
arrival warning appears with the option to cancel navigation (goto or route). yes the navigation is cancelled, no navigation continues however XTE and highway are no longer displayed.
