INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
This device must be installed according to these instructions.
Before applying power to this product, make sure it has been correctly grounded according to these
instructions.
CAUTION
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
NOTICE
Do not use the stereo as a template when drilling the mounting holes because this may damage the glass
display and void the warranty. You must only use the included template to correctly drill the mounting holes.
You must read all installation instructions before beginning the installation. If you experience difficulty during
the installation, contact Fusion Product Support.

GUID-DA740304-7C70-417A-8779-630F09652A74 v3October 2022
Mounting Considerations
• The stereo can be mounted on a flat surface or in a single-DIN opening as a replacement for an existing
stereo.
• The stereo must be mounted in a location that allows open airflow around the rear of the stereo for heat
ventilation.
• If you are installing the stereo in a location that may be exposed to water, it must be mounted within 45
degrees of the horizontal plane.
• If you are installing the stereo in a location that may be exposed to water, the cable should have a drip loop to
allow water to drip down off the cable and avoid damage to the stereo.
• If you need to mount the stereo outside a boat, it must be mounted in a location far above the waterline,
where it is not submerged.
• If you need to mount the stereo outside a boat, it should be mounted in a location where it cannot be
damaged by docks, pilings, or other pieces of equipment.
• To avoid interference with a magnetic compass, the stereo should be installed at least 15cm (5.9in.) away
from a compass.

Mounting the Stereo in a New Location
NOTICE
Be careful when cutting the hole to mount the stereo. There is only a small amount of clearance between the
case and the mounting holes, and cutting the hole too large could compromise the stability of the stereo after it
is mounted.
Before you can mount the stereo in a new location on the mounting surface, you must select a location in
accordance with the mounting considerations.
1Trim the template and make sure it fits at the mounting location.
2Adhere the template to the mounting surface.
3Using a drill bit appropriate for the mounting surface, drill a hole inside the corner of the dashed line on the
template to prepare the mounting surface for cutting.
4Using a rotary-cutting tool, cut the mounting surface along the inside of the dashed line on the template.
5Place the stereo in the cutout to test the fit.
6If necessary, use a file and sandpaper to refine the size of the cutout.
7After the stereo fits correctly in the cutout, ensure the mounting holes on the stereo line up with the pilot
holes on the template.
8If the mounting holes on the stereo do not line up, mark the new pilot-hole locations.
9Using an appropriately sized drill bit for the mounting surface and screw type, drill the pilot holes.
10 Remove the template from the mounting surface.
11 Make the necessary wiring connections (Connection Considerations, page4).
12 Place the mounting gasket on the back of the stereo .

13 Place the stereo in the cutout.
14 Secure the stereo to the mounting surface using the included screws .
15 Snap the screw covers in place .
Replacing an Existing Stereo
1Remove and disconnect the existing stereo.
2If necessary, remove the existing wiring harness or install a vehicle- or vessel-specific wiring-harness adapter
(not included) to provide access to the power and speaker wiring.
3Place the mounting gasket on the back of the stereo .
4Place the mounting bracket behind the mounting surface.
5Make the necessary wiring connections (Connection Considerations, page4).
6Place the stereo in the opening.
7Secure the stereo to the mounting bracket using the included screws .
NOTE: You might need to reach behind the mounting surface to hold the bracket in place when securing the
stereo to the bracket.
8Snap the screw covers in place .
Connection Considerations
The stereo must be connected to power, to speakers, and to media input sources to function correctly. You
should carefully plan the layout of the stereo, wired remote, speakers, optional NMEA 2000® network, and your
input sources before making any connections.

Port Identification
Item Description
ANT
Connects the stereo to a typical AM/FM antenna using an RF coaxial connector.
If you are installing the stereo on a boat with a metal hull, you must use a ground-dependent
antenna, and if you are installing the stereo on a boat with a non-metal hull, you must use a
ground-independent antenna. See the installation instructions provided with your antenna for
more information.
SXM TUNER Connects to a SiriusXM® tuner to receive SiriusXM channels where available (not included).
NMEA Connects the stereo to a NMEA 2000 network (NMEA 2000 System Wiring Diagram, page11).
USB Connects the stereo to a USB source.
FUSE Contains the fuse for the device.
See the device specifications for replacement fuse information.
Connects the stereo to the power and speaker wiring harness.
Connects the stereo to the auxiliary in and line/subwoofer out wiring harness.
Reserved for future use.

Wiring Harness Wire and Connector Identification
6
Wire Function Wire Color/
Number Notes
Power (+)
Red (yellow
on some wire
harnesses)
Connects to the positive terminal of a 12Vdc power source
capable of supplying 15A.
Ground (-) Black
Connects to the negative terminal of a 12Vdc power source
capable of supplying 15A. This wire should be connected before
connecting the red (or yellow) wire. All accessories connected to
the stereo must share a common ground location.
Amplifier on Blue Connects to an optional external amplifier to turn it on when the
stereo turns on.
Mute Brown
Activates when connected to ground.
For example, when connected to a compatible hands-free mobile
kit, the audio mutes or the input switches to AUX when a call is
received and the kit connects this wire to ground. This function
ality can be configured from the settings menu.
Dim Orange
Connects to the boat's illumination wire to dim the stereo screen
when the lights are on.
The gauge of the illumination wire must be suitable for the fuse
supplying the circuit it is connected to.

such as a CD or MP3 player.
Zone 1 line out (left)
Zone 1 line out (right)
Provides a full-range output to an external amplifier, and is asso
ciated with the volume control for zone 1.
Zone 2 line out (left)
Zone 2 line out (right)
Provides a full-range output to an external amplifier, and is asso
ciated with the volume control for zone 2.
Subwoofer out
Each cable provides a single mono output to a powered
subwoofer or subwoofer amplifier, and one or both cables can
be used, depending on the connection requirements of the
subwoofer or amplifier.
A connected subwoofer is associated with the volume control for
zone 1.

Connecting to Power
When connecting the stereo to power, you should connect it through the ignition or another manual switch.
If it is necessary to extend the power and ground wires, use 14AWG (2.08mm2) wire. For extensions longer
than 1m (3ft.), use 12AWG (3.31mm2) wire.
1Route the red power wire to the ignition or another manual switch , and route the black ground wire
to the battery.
2If necessary, route a wire between the switch and the battery .
3Route the wiring-harness plug to the stereo.
Do not connect the wiring harness to the stereo until after all of the bare wire connections have been made.
4Connect the black wire to the negative (-) battery terminal.
5Connect the red power wire to the ignition or another manual switch, and connect the switch to the positive
(+) battery terminal if necessary.
6Connect the wiring harness plug to the stereo.
Speaker Zones
You can group speakers in one area into speaker zones. This enables you to control the audio level of the zones
individually. For example, you could make the audio quieter in the cabin and louder on deck.
You can set the balance, volume limit, subwoofer level, and name for each zone.
