Connecting the Device to a Transducer
Only sonar-compatible devices are capable of receiving depth
information from a Garmin transducer. Sonar-compatible
devices have a port labeled 8-PIN SONAR or 12-PIN SONAR.
Go to
www.garmin.com
or contact your local Garmin dealer to
determine the appropriate type of transducer for your needs.
1
Follow the instructions provided with your transducer to
correctly install it on your boat.
2
Route the transducer cable to the back of your device, away
from sources of electrical interference.
3
Connect the transducer cable to the 8-PIN SONAR or 12-PIN
SONAR port on your device.
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 (not
included) in an appropriate location and connect it to the device
to provide GPS information.
Not all devices in the series are able to receive data from an
external GPS antenna. Compatible devices have a port labeled
EXT GPS.
1
Follow the instruction provided with your Garmin external
GPS antenna to correctly install it on your boat.
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.
Connecting the Device to a Garmin Marine
Radar
Only radar-compatible devices are capable of receiving
information from a Garmin Marine Radar. Radar-compatible
devices have a port labeled RADAR. Go to
contact your local Garmin dealer to determine the appropriate
type of radar for your needs.
1
Follow the instructions provided with your radar to correctly
install it on your boat.
2
Route the Garmin Marine Network cable from the radar to
the back of your device, away from sources of electrical
interference.
3
Connect the Garmin Marine Network cable to the RADAR
port on your device.
NOTE: Do not connect the network cable to the ETHERNET
port if one is present on your device. The ETHERNET port is
reserved for future use.
Updating the Device Software
The device may contain a software-update memory card. If so,
