Mounting the Microphone Hanger
NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended
to use a countersink bit to drill a clearance counterbore through only the top
gel-coat layer. This will help to avoid cracking in the gel-coat layer when the
screws are tightened.
Stainless-steel screws may bind when screwed into fiberglass and
overtightened. It is recommended to apply an anti-seize lubricant on the
screws before installing them.
You can mount the microphone hanger in a convenient location near the radio.
1
Select a mounting location for the microphone within reach of the
microphone cable.
2
Using the microphone hanger
as a template, mark the pilot holes.
3
Drill the mounting holes using a 3 mm (

VHF antenna
You must connect the device to a VHF antenna (sold
connection
separately) (Connecting a VHF Antenna, page 3).
NMEA 2000
You can connect this device to a NMEA 2000 network on your
®
connector
boat to share DSC and GPS information (optional) (NMEA
2000 Device Connections, page 3).
Connecting the Wiring Harness to Power
1
Route the wiring harness to the power source and to the device.
2
Connect the red wire to the positive (+) battery terminal, and connect the
black wire to the negative (-) battery terminal.
Additional Grounding Considerations
This device should not need any additional chassis grounding in most
installation situations. If interference is experienced, the grounding screw on
the housing can be used to connect the device to the water ground of the boat
to help avoid the interference.
Connecting a VHF Antenna
1
Mount the VHF antenna (sold separately) according to the installation
instructions provided with the antenna.
2
Connect the VHF antenna to the antenna port on the back of the radio.
NMEA 2000 Device Connections
NOTICE
If you are connecting this device to an existing NMEA 2000 network, the
NMEA 2000 network should already be connected to power. Do not connect
the NMEA 2000 power cable to an existing NMEA 2000 network, because only
one power source should be connected to a NMEA 2000 network.
If you are connecting this device to an existing NMEA 2000 network or engine
network by another manufacturer, you should install a NMEA 2000 Power
Isolator (010-11580-00) between the existing network and the Garmin devices.
If you are installing a NMEA 2000 power cable, you must connect it to the boat
ignition switch or through another in-line switch. NMEA 2000 devices will drain
your battery if the NMEA 2000 power cable is connected to the battery directly.
To connect this device to your existing NMEA 2000 network, you must
purchase a NMEA 2000 cable and connector.
If you are unfamiliar with NMEA 2000, you should read the "NMEA 2000
Network Fundamentals" chapter of the Technical Reference for NMEA 2000
