• You can connect the radio to a GPS source through the NMEA 2000
network or through an external GPS antenna (not included).
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 ANT port on the back of the device.
Connecting the Active Speaker to the VHF Radio and Handset
Before you connect the active speaker to the VHF radio and handset, you
should mount the active speaker (Active Speaker Mounting Considerations,
page 2).
1
Route the female end of the included extension cable from the speaker
mounting location to the VHF radio.
2 Connect the extension cable to the GHS 11 STATION 1 port on the VHF
radio.
3 Connect the male end of the extension cable to the short cable from the
active speaker.
4
Route the long cable from the active speaker to the handset connector
mounting location.
5
If necessary, install the cable from the active speaker in the mounting
surface (Installing the Handset Connector in the Mounting Surface,
page 3).
6
Connect the handset to the long cable from the active speaker.
Connecting the Handset to the VHF Radio Using an Extension
Cable
If you install an active speaker with the handset, the handset connects to the
radio through the active speaker (Connecting the Active Speaker to the VHF
Radio and Handset, page 4).
1
Route the female end of the included extension cable from the handset
mounting location to the VHF radio.
2
Connect the extension cable to the GHS 11 STATION 1 port on the VHF
radio.
3
If necessary, install the handset connector on the extension cable in the
mounting surface (Installing the Handset Connector in the Mounting
Surface, page 3).
4
Connect the handset to the extension cable.
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
Products. Go to www.garmin.com/manuals/VHF315/.

Connecting the Device to a Remote GPS Antenna
This device must receive GPS information for proper functionality. You can
connect the device to a NMEA 2000 network with a GPS antenna, or you can
install a remote GPS antenna (not included) and connect it to the device.
1
Follow the instructions provided with your external GPS antenna to install it
on your boat correctly.
2
Route the antenna cable to the back of your device, away from sources of
electrical interference.
3
Connect the antenna cable to the GPS port on your device.
Connecting to a Hailer Horn or PA Speaker
You can connect the VHF radio to a hailer horn or public address (PA) speaker
(not included) to use a handset to make announcements.
1
If necessary, mount the hailer horn or PA speaker according to the
installation instructions provided with the device.
NOTE: To avoid feedback, you should mount the hailer horn or PA
speaker at least 3 m (10 ft.) away from, and facing away from, a handset.
2
Route or extend the wire from the hailer horn or PA speaker to the radio.
3
Connect the white wire on the radio wiring harness to the positive (+) wire
from the hailer horn or PA speaker.
4
Connect the green wire on the radio wiring harness to the negative (-) wire
from the hailer horn or PA speaker.
5
Cover the connections with waterproof tape or heat-shrink tubing.
