1
Route the yellow power
À
, red ignition
Á
, and black ground
Â
wires to the 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.
2
Connect the black wire to the negative (-) battery terminal.
3
If you are routing the red wire through the ignition or another
manual switch
Ã
, connect the red ignition wire to the ignition
or switch.
4
Connect the red wire to the yellow wire, install a 15 A fuse
Ä
as close to the battery as possible, and connect both wires to
the positive (+) battery terminal.
NOTE: If you are running the red wire through a fused switch,
it is not necessary to connect the red wire to the yellow wire
or to add an another fuse to the red wire.
Enabling Standby Mode
You can set the stereo to enter a low-power standby mode when
you press . When you press again, it takes less than the
typical 30 seconds to turn on.
NOTE: When the stereo is in low-power standby mode, it
continues to draw current from the battery. The maximum
current draw in standby mode is 200 mA.
Select > Settings > Standby Mode.
The stereo now enters standby mode when you press .
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.
Zones 1 and 2 are powered by the on-board amplifier. To use
the RCA line outputs and the RCA subwoofer outputs, you must
connect external amplifiers.
You can set the balance, volume limit, subwoofer level, and
name for each zone.
Subwoofer Connection Considerations
This stereo supports output to a powered subwoofer for each
zone.
The subwoofer outputs are mono line-level signals tied to the
corresponding zone volume.
A splitter is provided to connect this mono output to the stereo
input of a subwoofer amplifier. Additional splitters (not included)
are needed for additional subwoofer connections.
Speaker Amplifier Connection Considerations
This stereo supports output to an external amplifier for each
zone.
The zone outputs are stereo line-level signals tied to the zone
volume. A standard RCA cable (not included) is required to
connect each zone output to an external amplifier.
The blue wire from the wiring harness must be connected to
each amplifier to provide a signal to turn on the amplifier with the
stereo. If it is necessary to split or extend this blue signal wire,
use 22 AWG (0.33 mm
2
) wire.
Common Connections to the Stereo
You can connect a variety of additional media inputs and
outputs to the stereo, depending on the stereo model and the
devices to which you are connecting.
The connectors are color coded to assist you in making the
correct connections. For example, if your TV has RCA line out
ports, you can connect an RCA cable to the AUX IN 1 or AUX IN
2 connector on the stereo. This table lists some possible ways to
connect devices to the stereo.
NOTE: Not all connectors are available on all stereo models.

Ethernet and Wireless Support
You can connect a compatible FUSION-Link
™
MFD to the
entertainment system using the Ethernet port. See the
documentation provided with your MFD for more information.
NOTE: Some MFDs with Ethernet support may not be
compatible with FUSION-Link over Ethernet, but may be
compatible with FUSION-Link over NMEA 2000 instead.
You can connect a wireless Ethernet router to the entertainment
system to control the device with Wi‑Fi
®
. You can download free
apps from the Apple App Store
SM
for Apple devices. Android
™
apps are available through Google Play
™
.

Audio Return Channel
The Audio Return Channel (ARC) enables you to play the audio
from a television with HDMI technology over the stereo system
speakers.
ARC eliminates the need to connect a separate audio cable
from the television to the stereo. Typically, in televisions without
ARC, to play the audio from the television over the stereo
system speakers, you would need a separate cable. With ARC,
the HDMI cable sends the television audio to the stereo.
HDMI version 1.4 with ethernet cables support ARC. When
planning your stereo installation, check whether your devices
support ARC. Most devices that support ARC have an ARC
label on the HDMI connector that supports ARC.
