INSTALLATION
INSTRUCTIONS
Mounting Considerations
You can mount the camera upside-down or sideways. You can
reverse the camera image to use in rearview mode. See your
chartplotter owner's manual for instructions.
You should mount the camera in a location where it is
• not an obstacle in doorways or walkways.
• not exposed to extreme temperatures.
• not exposed to gas or oil.
• not exposed to radioactivity.
• not facing into direct sunlight or a direct reflection of sunlight.
Tools Needed
• 1 A fuse or circuit breaker
• Drill and 2 mm (
1
/
16
in.) drill bit

Installation Considerations
You must connect the camera power wire to the battery through
a 1 A fuse or circuit breaker. If you do not use a fuse or circuit
breaker, the camera can malfunction.
Some Garmin
®
GPSMAP
®
chartplotters have a built-in CVBS
video encoder. Video from the camera or cameras appears on
all chartplotters on the network when plugged into a single
CVBS IN port. Go to
www.garmin.com/manuals/gc12
for a list of
compatible GPSMAP chartplotters.
If you want to use more than one camera or the chartplotter
does not have a CVBS IN port, you must use an encoder.
You can add up to four cameras to one encoder and up to two
encoders to the Garmin Marine Network.

• Verify all cables are firmly connected.
• Verify the video cable is connected to the camera video
output port.

soft, clean cloth.

camera position or location.
