How GPS Works
Your Matrix Fishing System uses GPS and sonar to determine your position, display it on a grid, and
provide detailed underwater information. The Global Positioning System (GPS) is a satellite
navigation system designed and maintained by the U.S. Department of Defense. GPS was originally
intended for military use; however, civilians may also take advantage of its highly accurate position
capabilities, typically within +/- 10 meters, depending on conditions. This means that 95% of the
time, the GPS receiver will read a location within 10 meters of your actual position. The GR4 GPS
Receiver can use information from WAAS (the Wide Area Augmentation System), EGNOS (the
European Geostationary Navigation Overlay Service), and MSAS (the MTSAT Satellite Augmentation
System) satellites if they are available in your area.

GPS uses a constellation of satellites that continually send radio signals to the earth. Your present
position is determined by receiving signals from up to 12 satellites and measuring the distance from
the satellites.

5. The Matrix Control Head outputs NMEA signals thru the "pigtail" cable attached to the end
of the GR4 GPS Receiver Cable for connection to devices such as autopilots. Connect the
NMEA Out (White Wire) of the cable to the NMEA In of the device you are connecting to
your Matrix Fishing System. The pinouts of this cable are as follows:
Connecting a GR4 GPS Receiver to the Matrix
Here's how to access GPS functionality using your GR4 GPS Receiver Accessory:
1. Attach the GR4 GPS receiver to your Matrix Control Head COM port using the NMEA cable
attached to the antenna.
• Red Wire, +12V (output voltage only)
• Black Wire, Ground
2. If you are already using other Matrix accessories plugged into the COM connector, you will
also need to use the AS-YC ("Y") cable included in your GR4 GPS Hardware Kit so that you
can use both the accessories and your GPS Receiver at the same time. Attach the COM
connector of the "Y" cable directly to your Matrix Control Head COM port. Attach the GR4
GPS receiver to the NMEA-COM connector of the "Y" cable. Re-connect your Matrix
accessories to the ACCY-COM connector of the "Y" cable.
• White Wire, NMEA Out.
CAUTION! Please use caution before connecting the red +12V wire to any other NMEA device. This is an
output voltage provided by the Matrix unit and GR4 receiver and should only be connected to those
NMEA devices that need a 12 volt input.
3. Power up the Matrix Fishing System (see your Matrix Operation Manual for details).
GPS Receiver Installation
To optimize performance of the GPS receiver, mount it in an area that has full exposure to the sky.
The effective area of reception is 10° above the horizon.
4. When the Matrix detects the NMEA input from the GPS Receiver, the Combo, Track and
Bird's Eye Views will be added automatically to the VIEW key function. A Navigation menu
tab and the Navigation X-Press menu will also be added automatically to the Menu system.
Different circumstances determine the mounting method appropriate for your GPS receiver.

linked to the boat by a gray line, even if the boat is off the screen.
Both Track and Combo views allow you to choose the orientation of the view. When North-Up
orientation is selected, North is shown at the top of the display. In other words, objects located to
the north of the boat are drawn above the boat. When Course-Up orientation is selected, the
direction of motion of the boat is shown at the top of the display. In other words, objects ahead of
the boat are drawn above the boat. In both orientations, the view pans automatically, so that the
boat is always centered on the display. When the boat is stationary, it is drawn as a circle. When the
boat is in motion, it takes on a boat shape, pointed in the direction of motion (always Up in the
Course-Up orientation).

Troubleshooting
Display Problems
Before contacting the Humminbird® Customer Resource Center, please read the following section.
Taking the time to review these troubleshooting guidelines may allow you to solve a performance
problem yourself, and therefore avoid sending your unit back for repair.
There are several main conditions or sources of possible interference that may cause problems with
the quality of the information displayed on the control head. Look in the following table for some
symptoms of display problems and possible solutions:
Fishing System Doesn’t Power Up
Problem
Possible Cause
If your Matrix Fishing System doesn’t power up, use the Installation Guide that also comes with it
for specific confirmation details, making sure that:
The control head loses power at
high speeds.
If the power output of your boat’s engine is unregulated,
the control head may be protecting itself using its over-
voltage protection feature. Make sure the input voltage
does not exceed 20 Volts.
•
•
the power cable is properly connected to the Matrix Fishing System control head,
the power cable is wired correctly, with red to positive battery terminal and black to
negative terminal or ground
When the boat moves at higher
speeds, the bottom disappears
or suddenly weakens, or the
display contains gaps.
The transducer position may need to be adjusted. A mix
of air and water flowing around the transducer
(cavitation) may be interfering with the inter-pretation
of sonar data. See your Installation Guide for
suggestions on adjusting the transducer position.
•
•
the fuse is operational
the battery voltage of the power connector is at least 10 Volts.
Correct any known problems, including removing corrosion from the battery terminals or wiring, or
actually replacing the battery if necessary.
Fishing System Defaults to Simulator with a Transducer Attached
Electrical noise from the boat’s engine may be
interfering with sonar reception. See Finding the Cause
of Noise for more information.
A connected and functioning transducer will cause the newly-started Matrix Fishing System to go
into Normal operating mode automatically. If, when you power up the Matrix Fishing System, it goes
into Simulator mode automatically, even though a transducer is already connected, this means that
the control head is not detecting the transducer. Perform the following troubleshooting tasks:
There are no fish detected, even
when you know they are in the
water under the boat, or sonar
readings seem weak or faulty.
Sonar readings may be affected if the transducer is not
positioned correctly (i.e. mounted at an angle, not
straight down), or there is some kind of mechanical
interference, either because it is mounted inside a hull
that is too thick for proper sonar transmission, the bond
between the transducer and the hull is not airtight, or
because the transducer is dirty. Check with your
Installation Guide for guidance on re-positioning the
transducer, and make sure the transducer is clean.
•
Using the Installation Guide that also comes with your Matrix Fishing System, check to
make sure that the transducer cable is securely connected to the Matrix Fishing System.
Reconnect if necessary, and power up the Matrix Fishing System again to see if this fixes
the problem.
•
•
Replace the non-functioning transducer with a known good transducer if available and
power up the control head again.
Check the transducer cable. Replace the transducer if the cable is damaged or corroded.
Low battery voltage may be affecting the power of
signal transmission.
Electrical noise from the boat’s engine may be
interfering with sonar reception. See Finding the Cause
of Noise for more information.

Finding the Cause of Noise
Matrix Fishing System Accessories
Electrical noise usually affects the display with many black dots at high speeds, and high sensitivity
readings. One or more of the following sources can cause noise or interference:
Accessories customize the Matrix Fishing System to your needs and enable you to stay on the edge
of new technology. When an accessory is connected to the Matrix Fishing System, additional menus
and readouts are added automatically to the Main Menu System. Accessories available today that
are supported by your Fishing System include:
Possible Source of Noise
Other electronic devices
Isolation
WeatherSense™ Fishing Condition Monitor: purchase and plug in the WeatherSenseTM accessory to
your Matrix Fishing System to obtain barometric pressure readouts and trend data in real time.
Turn off any nearby electronic devices to see if the
problem goes away, then turn them on one at a time to
see if the noise re-appears.
Wireless Sonar Link (WSL): purchase the Wireless Sonar Link (WSL) accessory to receive remote
sonar signals from a SmartCastTM Remote Sonar Sensor (RSS). Radio signals from the RSS are received
by the WSL and are transmitted over the Accessory Bus to the Matrix Fishing System.
The boat’s engine
To determine whether the boat’s engine is the source of
the noise, increase the RPMs while the boat is in neutral
and stationary to see if the noise increases pro-
portionately; if noise appears when you rev the engine,
the problem could be the spark plugs, alternator, or
tachometer wiring. Replace the spark plugs with resistor
plugs, install an alternator filter, or route the control head
power and transducer cables away from the engine
wiring.
PC Connect Cable: Purchase the PC Connect Cable to connect the Matrix Fishing System to a PC in
This accessory requires the MSWindows-compatible HumminbirdPC™ software downloaded from
our website to your PC in order to communicate with the Matrix Fishing System.
to grow your Matrix Fishing System!
or contact our Customer Resource Center at 1-334-687-0503 for additional details.
Cavitation from the boat’s
propeller
Turbulence created by the propeller can cause noise;
make sure the transducer is mounted at least 15” (38 cm)
from the propeller, and that the water flows smoothly
over the face of the transducer at all times.
