INTRODUCTION
Warning
Failure to avoid the following potentially hazardous situations
could result in an accident or collision resulting in death or
serious injury.
When navigating, carefully compare information received from the
GPS 17 to all available navigation sources, including information
from street signs, visual sightings, and maps. For safety, always
resolve any discrepancies or questions before continuing
navigation.
WARNING: This product, its packaging, and its components contain chemicals known to the State of California to cause cancer, birth defects,
or reproductive harm. This Notice is being provided in accordance with California’s Proposition 65. If you have any questions or would like
additional information, please refer to our Web site at http://www.garmin.com/prop65.
Use an electronic chart in conjunction with the GPS 17 only to
facilitate, not to replace, the use of authorized government charts.
Official government charts and notices to mariners contain all
information needed to navigate safely.
Caution
Failure to avoid the following potentially hazardous situations
may result in injury or property damage.
Use the GPS 17 only as a navigational aid. Do not attempt to use
the GPS 17 for any purpose requiring precise measurement of
direction, distance, location, or topography. This product should
not be used to determine ground proximity for aircraft navigation.
ii GPS 17 Installation Guide
The Global Positioning System (GPS) is operated by the United
States government, which is solely responsible for its accuracy
and maintenance. The government’s system is subject to changes
which could affect the accuracy and performance of all GPS
equipment, including the GPS 17. Although the GPS 17 is a
precision navigation device, any navigation device can be misused
or misinterpreted and, therefore, become unsafe.

MOUNTINGTHE GPS 17
Mounting Location Tips
• Position the receiver so that it has the clearest
possible view of the sky and horizon in all directions.
• Avoid mounting the antenna next to large areas of
conductive material (metal, aluminum, etc.) as this
may cause poor signal reception.
• Do not mount the GPS 17 high on a mast, as the top
of the mast travels more than the boat. The unit will
provide more stable readings if it is located near the
water level.
To flush mount the GPS 17:
1. Turn the GPS 17 upside down. To create a template,
punch a hole in the three mounting screw holes.
2. Use the template to mark the hole locations on the
mounting surface. The centers of the holes are 2.44”
(62 mm) apart. Use an 11/64” drill bit to drill a hole at
each marked location.
3. Align the GPS 17 over the three holes and fasten the
M4 screws. The threads are 8.10 mm deep: do not
use screws that will thread into the base any deeper,
as this may damage the GPS 17.
• When routing the wiring to the GPS 17, avoid routing
the cable near the vessel’s alternator or ignition
system components or parallel to other power lines.
Mounting
hole
• As a general rule, mount the receiver at least three
feet from all other antennas and the vessel’s electrical
system components (alternator/ignition system).
• The GPS 17 is supplied with a 30-foot power/data
cable. Be sure that the cable can be routed to the
necessary devices.

To attach the enclosed pole to the base:
1. Thread the cable though the pole mount.
2. Align the tab on the pole to the notch on the base.
3. Use the enclosed screws to secure the pole to the
base.
To mount the GPS 17 with cable outside mount:
1. Place the cable in the vertical slot along the side of
the base of the unit.
2. Screw the GPS 17 onto the mount. Do not
overtighten: it is possible to tighten the unit to the
point that the cable may be cut in two.
3. Fill the remaining gap in the cable exit with marine
sealant.

MOUNTINGTHE GPS 17
To mount the GPS 17 with cable through mount:
1. Position the mount in the desire location and mark
the approximate center of the mount
2. Drill a hole large enough for the cable to pass
through at the marked location.
3. Slide the cable through the mount and screw the
GPS 17 onto the mount.
4. Fasten the mount to the boat.

GPS 17 Installation Guide 5
Routing the Cable
You can shorten or coil excess cable and secure it in an
inconspicuous location. When routing the power/data cable,
try to avoid the following things:
• Sharp edges that can cut the cable.
• Routing the cable parallel to other power lines.
• Excessively twisting, straining or bending the cable.

WIRINGTHE GPS 17
To wire the GPS 17 to a NMEA Device or PC
Connector:
1. Connect the White (Port 1 Data Out) wire from the
GPS 17’s power/data cable to the DATA INPUT line
of the NMEA device or to pin 2 on a DB-9 (pin 3 on
DB-25).
2. Connect the Blue (Port 1 Data In) wire to the DATA
OUTPUT line of the NMEA device or pin 3 on the
DB-9 (pin 2 on DB-25).
3. Connect the Black (-) wire to the GROUND wire of
the NMEA device and/or pin 5 on the DB-9 (pin 7
on DB-25). If connecting to a PC, the Black (-) wire
must also be run to a ground.
If the Black wire is connected to the same ground
terminal as the NMEA device, no additional
connection is required, unless a separate data return
line is required by the NMEA device.
4. Connect the Red (+) wire from the power/data cable
to a 8–40 VDC power source.
GPS 17 Installation Guide 9
5. If the receiver is being wired to a circuit that is
already switched, (with the NMEA device for
example) connect the Yellow wire to the same place
as the Black wire. When the Black and Yellow wires
are combined, the GPS 17 will turn on/off when
power is applied/removed to the Red (+) wire.
If a remote power switch is being installed, refer to
Figure 6 on page 7. This will allow the GPS 17 to
remain connected to a power source but manually
powered on (pull down to less than 0.5 volts) and off
(open).
Some non-Garmin devices may have a separate data line
labeled RETURN, DATA GROUND, or DATA -. If one of
these lines exist, connect the Black wire from the power/
data cable to it.
You may output data to up to three NMEA devices. The
number of devices is determined by the total amount of
impedance from all devices.

given an opportunity to collect satellite data and determine
its present position. To ensure proper initialization, the GPS

17 is shipped from the factory in AutoLocate
mode, which
allows the receiver to “find itself” anywhere in the world.
When turned on, the GPS 17 searches for satellites. After
it has calculated an initial position fix, the GPS 17 outputs
navigation data. For more information about the data
output by the GPS 17, refer to the GPS 16/17 Technical Specifications located on the Garmin Web site.

stations and create a GPS data correction message. Initial
reception of the WAAS signal may take up to 20 minutes.
According to the FAA’s Web site, testing in September 2002
of WAAS confirmed an accuracy performance of 1–2 meters
horizontal and 2–3 meters vertical throughout the majority
of the continental United States and portions of Alaska. For

WAAS is just one service provider that adheres to the

Satellite Based Augmentation Systems (SBAS). Eventually,
there will be several services of worldwide geostationary
communication satellites and ground reference stations.
All SBAS systems use the same receiver frequency and are
capable of providing your GPS unit with increased accuracy
at any location in the world.
