Wiring to an Optional Alarm
The GPSMAP 3000 series chartplotter can be used with a lamp, a horn, or both, to sound or flash an alert when the chartplotter displays a
message. The alarm does not need to be wired for the GPSMAP 3000 chartplotter to function. The alarm circuit switches to a low-voltage state
when the alarm sounds. The maximum current is 100 mA, and a relay (not included) is needed to limit the current from the chartplotter to 100
mA. To select between visual and audible alerts, install a switch.

Chartplotter
Marine Video Cable
The GPSMAP 3006/3206/3010/3210 chartplotters have video input and output capabilities, and a video cable is provided with those units. The
GPSMAP 3005/3205 chartplotters do not have video input or output capabilities, so no cable is provided with those units.
The Marine Video 17-pin cable allows input of NTSC (National Television System Committee)/PAL (Phase Alternate Line) composite video
sources, and PC monitor output. Marine Video inputs are only available on the chartplotter to which they are attached and will not transmit over
the Garmin Marine Network.
➊ and ➋ VIDEO 1 and VIDEO 2 Inputs (RCA connectors) allow input from two separate NTSC/PAL compatible video devices, such as VCR,
DVD, TV, or a video camera. The chartplotter can display one video input at a time or alternate between the two. See the owner's manual for
details. Sound from a video source must be attached to a separate stereo/audio system. The video output from video device attaches to the
Video 1 (Black Cable) or Video 2 (Gray Cable) RCA connectors.
➌ Use the PC monitor output (HD 15-pin) connector for remote viewing of the chartplotter display on a computer monitor. The remote monitor
must be capable of at least VGA resolution and have multi-sync capability.
