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.

Ground (-) Black Connects to the negative terminal of
a 12 Vdc power source capable of
supplying 15 A. You should connect
this wire before connecting the yellow
wire. All accessories connected to the
stereo must share a common ground
location (Connecting to Power,
page 2).
Power (+) Yellow Connects to the positive terminal of a
12 Vdc power source capable of
supplying 15 A.
Ignition Red Connects 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 Connects to optional external
amplifiers, enabling them to turn on
when the stereo turns on.
A connected amplifier must use the
same ground (-) as the stereo for this
signal wire to function correctly.

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.

Connecting to Power
When connecting the stereo to power, you must connect both
power wires. You should connect the yellow power wire directly
to the battery. This provides power to the stereo and a constant
trickle-power standby feed.
You should connect the red ignition wire 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 through the ignition
or another manual switch, you can connect the red wire to the
yellow wire, and connect them both to the positive (+) battery
terminal.
You must connect the power wires to the battery through a 15 A
fuse or a 15 A circuit breaker.
If it is necessary to extend the yellow power and black ground
wires, use 14 AWG (2.08 mm
2
) wire. For extensions longer than
1 m (3 ft.), use 12 AWG (3.31 mm²) wire. If it is necessary to
extend the red wire, use 22 AWG (0.33 mm
2
) wire.
