If necessary, place the nut plates
15
Place the stereo in the cutout.
16
Secure the stereo to the mounting surface using the included screws
17
If necessary, secure the back of the stereo with a back strap or brace (not
included).
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
sources before making any connections.

Wire Function Wire Color Notes
Power (+) Yellow This should be connected to a constant 12 Vdc
source capable of supplying 15 A. All 12 V wiring
must be fused at the power source end of your
cable using a 15 A fuse.
Ground (-) Black This should be connected battery negative before
connecting the yellow wire. All accessories
connected to the stereo must share a common
ground location.
Ignition Red This should be connected to a separately switched
12 Vdc connection, such as an ignition bus, to turn
the stereo on and off. If you are not using a
switched 12 Vdc connection, you must connect this
to the same source as the yellow (power) wire.
Amplifier on Blue This is connected only when using an optional
external amplifier.
Telephone Mute Brown When connected to ground and a call is received
on a hands-free mobile phone, this mutes the audio
or switches the input to AUX IN 2 or ARC source
(ARC source is available on the MS-AV755 only).
This is configurable in the Settings menu.
Dim Orange This can be connected to the boat's illumination
wire to dim the stereo screen when the lights are
on.
This must be connected to a wire gauge 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 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 red wire to the yellow wire, and connect them to the positive
(+) battery terminal.
If it is necessary to extend the yellow power and black ground wires, use
2
14 AWG (2.08 mm ) 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 mm
