Connecting the Device to a Remote GPS Antenna
This device has an internal GPS receiver, but some
installations, such as a flush-mount installation, may not allow a
view of the sky needed to calculate your GPS position. In this
situation, you can install a Garmin external GPS antenna and
connect it to the device to provide GPS information.
Devices that can receive information from a Garmin external
GPS antenna have a port labeled EXT GPS.
1
Follow the instruction provided with your Garmin 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 EXT GPS port on your
device.
NMEA 2000 Considerations
NOTICE
If you have an existing NMEA 2000 network on your boat, it
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 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.
NMEA 2000 compatible models can connect to a NMEA 2000
network on your boat to share data from NMEA 2000
compatible devices such as a VHF radio. The necessary NMEA
2000 cables and connectors are sold separately.
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
The port labeled NMEA 2000 on the back of the device is used
to connect it to a standard NMEA 2000 network.
