FUSION® MS-BB300 Installation
Instructions
Important Safety Information
WARNING
Failure to follow these warnings and cautions could result in
personal injury, damage to the vessel, or poor product
performance.
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.
Disconnect the vessel's power supply before beginning to install
this product.
Before applying power to this product, make sure it has been
correctly grounded, following the instructions in the guide.
CAUTION
Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.
NOTICE
When drilling or cutting, always check what is on the opposite
side of the surface.
You must read all installation instructions before beginning the
installation. If you experience difficulty during the installation,
contact FUSION Product Support.
Software Updates
For best results, you should update the software in all FUSION
devices at the time of installation to ensure compatibility.
Go to www.fusionentertainment.com/marine to download the
latest software. Software updates and instructions are available
on your device product page.
• To avoid interference with a magnetic compass, the device
should be installed at least 203 mm (8 in.) away from a
compass.
Mounting the FUSION BB300 Device
NOTICE
If you are mounting the device in fiberglass, when drilling the
pilot holes, it is recommended to use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This
will help to avoid cracking in the gel-coat layer when the screws
are tightened.
NOTE: Stainless-steel screws may bind when screwed into
fiberglass and overtightened. It is recommended to apply an
anti-seize lubricant to the screws before installing them.
NOTE: Screws are included with the device, but they may not
be suitable for the mounting surface.
Before you mount the device, you must select a mounting
location and determine what screws and other mounting
hardware are needed for the surface.
Place the device in the mounting location and mark the
1
location of the pilot holes.
Drill a pilot hole for one corner of the device.
2
Loosely fasten the device to the mounting surface with one
3
corner and examine the other three pilot-hole marks.
Mark new pilot-hole locations if necessary, and remove the
4
device from the mounting surface.
Drill the remaining pilot holes.
5
Secure the device to the mounting location.

Connection Considerations
The device must be connected to power, either the boat ignition
or an external switch, a NMEA 2000® network, speakers, and
media input sources to function correctly. You should carefully
plan the layout of the device, the NMEA 2000 network, the
speakers, and your input sources before making any
connections.

Mounting Considerations
CAUTION
In high ambient temperatures and after extended use, the
device enclosure may reach temperatures deemed dangerous
to touch. Therefore the unit must be installed in a location where
it will not be touched during operation.
NOTICE
This device should be mounted in a location that is not exposed
to extreme temperatures or conditions. The temperature range
for this device is listed in the product specifications. Extended
exposure to temperatures exceeding the specified temperature
range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.
• The device must be mounted in a location where it is not
submerged.
• The device must be mounted in a location with adequate
ventilation where it is not exposed to extreme temperatures.
• The device should be mounted so that the cables can be
connected easily.
• To achieve IPX3 water ingress protection and optimal heat
sink cooling, the device must be mounted on a vertical
surface with the connectors pointing downward.
• The device can be mounted on a horizontal surface, but such
positioning might not achieve IPX3 water ingress protection.

mutes the audio or switches the
input to AUX2. This is available in
the settings menu.
Connecting to Power
When connecting the stereo to power, you must connect both
power wires. The yellow power wire should be connected
directly to the battery, or connected using a 15 A isolator switch.
This provides power to the stereo and a constant trickle-power
standby feed. The red signal wire should be connected to the
same battery through the ignition or another manual switch to
turn the stereo on and off.
If you are not routing the red wire to the ignition or another
manual switch, you can connect the yellow to the red, and
connect them to the positive (+) battery terminal. You should put
a fuse on the red wire.
If it is necessary to extend the yellow power and black ground
wires, use 14 AWG (2.08 mm2) wire. For extensions longer than
1 m (3 ft.), use 12 AWG (3.31 mm²) wire.
If it is necessary to extend the red signal wire, use 22 AWG
(0.33 mm2) wire.
Route the yellow power À and black ground Á wires to the
1
battery and route the wiring-harness plug to the stereo.
Do not connect the wiring harness to the stereo until all of the
bare wire connections have been made.
• Connect the yellow wire to the positive (+) battery
terminal, and route the red signal wire  to the ignition or
another manual switch Ã.
• Connect the yellow wire to the red, and connect them to
the positive (+) battery terminal.
NMEA 2000 Connection Considerations
NOTICE
If you purchased the stereo and remote as a bundle (FUSION
MS-BB300R), do not use the included adapter cable
(CAB000862) to connect the FUSION BB300 stereo to an
existing NMEA 2000 network. Existing networks are normally
powered separately. You must obtain a non-powered drop cable
(CAB000863) from FUSION to connect to existing NMEA 2000
networks.
The FUSION MS-BB300 stereo can connect to an existing
NMEA 2000 network or to a FUSION NRX remote control.
Through the NMEA 2000 network, you control the FUSION MSBB300 device using a compatible chartplotter or FUSION NRX
remote control.
The FUSION MS-BB300R stereo and remote bundle package
includes the cables needed to connect the FUSION BB300
stereo to a stand-alone FUSION remote control network. If you
need to connect the FUSION MS-BB300R stereo and remote
bundle to an existing NMEA 2000 network, you must obtain a
non-powered drop cable (CAB000863) from FUSION.
The FUSION MS-BB300 stereo package includes a NMEA 2000
drop cable to connect the FUSION BB300 stereo to an existing
NMEA 2000 network. A standard NMEA 2000 drop cable is not
compatible with the connector on the device, although the
included cable can be extended to a maximum length of 2 m
(6 ft.) using a standard NMEA 2000 cable.
