Installing the GPS 17
The GPS 17 can be flush mounted or installed on any standard 1" O.D. (Outer
Dimension), 14 threads-per-inch marine mount. When mounting the GPS 17, the
cable can be run externally, through the mounting panel, or through the center of
the marine mount.
The GPS 17 connects to the 18-pin Power/Data Cable on the GPSMAP 3005C
and provides the GPS/WAAS signal for the unit. If two or more
GPSMAP 3005C/3006C/3010C units are installed and networked, only one
GPS 17 needs to be installed.
To ensure the best reception, mount the GPS 17 in a location that has a clear,
unobstructed view of the sky in all directions. Avoid mounting the GPS 17 where
it is shaded by the boat's superstructure, a radome antenna, or mast. Sailboat
users should avoid mounting the unit high on the mast to prevent inaccurate speed
readings caused by excessive heeling. The unit provides more stable readings if
it is located nearer to water level. Mount the GPS 17 at least 3 ft away from
(preferably above) the path of any radar beam or a VHF radio antenna.
Temporarily secure the unit in the preferred mounting location and test for
correct operation. With correct operation verified, permanently mount the unit. If
interference with other electronics is experienced, try a different location.
NOTE: Never paint the GPS 17 or clean it with harsh solvents.
To flush mount the GPS 17:
1. Cut out the Mounting Template provided on page 12, and tape it on the selected mounting location.
2. Mark the center of each mounting hole by tapping the end of a center punch or pointed object with a hammer. If the cable is going to be
installed through the mounting panel, mark the center of the additional hole.
3. Drill the holes using the appropriate drill bit(s).
4. Align the GPS 17 over the mounting holes and fasten using M4 screws. The mounting threads in the GPS 17 are 8.10 mm deep, do not
use screws that thread into the GPS 17 deeper than 8 mm, or the case may be damaged.
The GPS 17 can be installed with the coax through the panel
or on the outside of the unit. If the coax is run through the
panel, seal the outside exit area with marine sealant.
