Mounting the GPSMAP 168 Sounder Unit
The GPSMAP 168 Sounder’s compact, waterproof case is suitable for mounting in exposed loca-
tions or at the nav station. The unit comes with a gimbal bracket for surface or overhead mounting.
When choosing a location for the display unit, make sure you consider the following conditions:
• There should be at least a 3” (5 cm) clearance behind the case to allow connection of the
antenna (external antenna only) and power/data cables.
• The mounting surface should be heavy enough to support the unit and protect it from excessive
vibration and shock.
• For units with the built-in internal bail mount antenna, it should be mounted in a location that has
the clearest, most unobstructed view of the sky in all directions to ensure the best reception. Avoid
mounting the unit where it will be blocked by the boat’s superstructure, a radar arch or mast.
The temperature range for the GPSMAP 168 Sounder is 5°F to 158°F (-15°C to 70°C).
Extended exposure to temperatures exceeding this range (in storage or operating
conditions) may cause failure of the LCD screen. This type of failure and related
consequences are NOT covered by the manufacturer’s limited warranty.
To install the GPSMAP 168 Sounder unit:
1. Place the mounting bracket in the desired location.
2. Mark and drill the four mounting holes for the fastener you are using.
3. Fasten the bracket to the surface using the appropriate fastener.
4. Insert the GPSMAP 168 Sounder into the mounting bracket. The bracket is designed for a tight fi t to
provide additional support when swiveling the unit.
5. Screw the two mounting knobs through the bracket and into the display case.
6. Connect the power/data and antenna cables (external antenna only) to the back of the unit, making
sure the locking rings are fully tightened on both connectors.

The Mounting Bracket is designed to be secured using a
fl at head screw. If you use a screw with a countersunk
head, you risk damaging the Mounting Bracket.
