Installation Guide

9
Secure the stereo to the mounting surface using the included
screws
.
You should hand-tighten the screws when securing the
stereo to the mounting surface to avoid over tightening them.
10
Snap the screw covers in place
.
Connection Considerations
The stereo must be connected to power, either through the boat
ignition or an external switch, 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.
Port Identification
Not used.
Connects the stereo to the wiring harness for auxiliary
input 1, and for the line and subwoofer outputs for zones
1 and 2.
Connects the stereo to the power and speaker wiring
harness.
FUSE Contains the 15 A fuse.
USB Connects the stereo to a USB source.
SXM TUNER Connects the stereo to a SiriusXM
®
Connect Tuner to
receive SiriusXM stations where available (not included).
Connects to a Fusion DAB module to receive DAB
stations where available (not included).
ANTENNA Connects the stereo to a typical AM/FM antenna.
If you are installing the stereo on a boat with a metal hull,
you must use a ground-dependent antenna. 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.
NMEA 2000 Connects the stereo to a NMEA 2000 network (NMEA
2000 System Wiring Diagram, page 4).

Ignition Red Connects to a separately-switched,
12 Vdc connection, such as an
ignition bus, to turn the stereo on
and off.
Amplifier on Blue Connects to optional external
amplifiers, enabling them to turn on
when the stereo turns on.
Maximum output current when
stereo is on: 100 mA.
Telemute Brown Activates when connected to
ground.
For example, when you connect this
wire 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. You can enable this
functionality 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.

Connecting to Power
When connecting the stereo to power, you must connect both
power wires. The yellow power wire must connect to the battery
to provide sufficient power to the stereo. The red ignition should
be connected through the ignition or another manual switch to
enable on/off control of the stereo. This installation method
provides the best performance because the yellow wire retains a
constant trickle-power draw that optimizes the startup time for
the stereo.
NOTE: If you will be storing the vessel for an extended period of
time, you should consider connecting the yellow wire through a
