3
Loosely fasten the device to the mounting surface with one
corner and examine the other three pilot-hole marks.
4
Mark new pilot-hole locations if necessary, and remove the
device from the mounting surface.
5
Drill the appropriate pilot holes for the other three marks.
6
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.

This should be connected to a
constant 12 VDC source capable
of supplying 15 Amps.
This should be connected to a
separate switched 12 VDC
connection, such as an ignition
bus, to turn the device 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.
This is connected only when
using an external amplifier on

Connecting to Power
When connecting the device to power, it is important to connect
both power wires. The yellow power wire should be connected
directly to the battery, or connected using a 15 Amp isolator
switch. This provides power to the device 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 device on and off.
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.
1
Route the yellow power
battery and route the wiring-harness plug to the device.
Do not connect the wiring harness to the device until all of
the bare wire connections have been made.
2
Connect the yellow wire to the positive (+) battery terminal,
and connect the black wire to the negative (-) battery
terminal.

NMEA 2000 Connection Considerations
This device connects to a NMEA 2000 network on your boat
using the included NMEA 2000 cable and connector. Through
the NMEA 2000 network, you control the device using a
connected Garmin device or optional remote control. If you do
not have an existing NMEA 2000 network on your boat, you
must create one.
NOTE: The included NMEA 2000 drop cable must be used to
connect the device to the NMEA 2000 network. A standard
NMEA 2000 drop cable is not directly 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.
If you are unfamiliar with NMEA 2000, you should read the
"NMEA 2000 Network Fundamentals" chapter of the Technical
Reference for NMEA 2000 Products. To download this
document, select Manuals on the product page for your device
at www.garmin.com.
