5. Secure the under-deck mount to the mounting surface with screws. Use extreme care to
ensure that the screws do not penetrate the upper surface of the deck.
6. Connect the power/data cable to the GPS 17x.
7. Route the cable away from sources of electronic interference, and connect it to your
NMEA 2000 network.
Step 2: Connect the GPS 17x Antenna to Your NMEA 2000
Network
The GPS 17x is packaged with a NMEA 2000 T-connector and a NMEA 2000 drop cable. You
will use these two components to connect the GPS 17x to your existing NMEA 2000 network.
If you do not have an existing NMEA 2000 network, you will need to install a NMEA 2000
network on your boat. For more information on NMEA 2000, visit www.garmin.com.
To connect the GPS 17x to
your existing NMEA 2000
network:
1. Determine an appropriate
location to connect the
GPS 17x to your existing
NMEA 2000 backbone.
2. Disconnect one side of a
NMEA 2000 T-connector
from the backbone nearest
to the location where you
want to connect the GPS 17x
antenna.
If you need to extend the
NMEA 2000 backbone,
connect an appropriate
NMEA 2000 backbone
extension cable (not
included) to the side of the T-
connector you disconnected.
6. Connect an included T-
connector in the NMEA 2000
backbone.
7. Route an included drop cable
from the GPS 17x antenna to the top of the T-connector you added to your NMEA 2000
network.
If the included drop cable is not long enough, you can add a drop cable extension up to
13 ft. (4 m). If more cable is needed, add an extension to your NMEA 2000 backbone, based
on the NMEA 2000 guidelines.
Step 3: Update Your Chartplotter
To ensure compatibility with the GPS 17x, upgrade your Garmin chartplotter with the latest
software. For more information, visit http://www8.garmin.com/support/download.jsp.
