Auto power wiring option
Black wire
: Connect this to the negative
battery terminal.
Red wire
: Connect this to the positive battery
terminal after the main switch. Fit a 2 Amp fuse
as shown.
Yellow wire
: To enable the engine hours coun-
ter and fuel counter; and to start the fishfinder
automatically when the ignition is turned on,
connect the yellow wire to the ignition system
through a 2 Amp fuse.
Note:
The fishfinder cannot be turned off while
the ignition is on.
Secondary alarm wiring option
Green Wire:
Use this to connect a secondary
alarm indicator such as a flashing light or exter-
nal beeper with a built-in drive circuit. See the
Auto power wiring diagram.
If the external beeper or light requires more than
200 mA total, fit a relay. Consult your Navman
dealer for more advice.
Fuel kit wiring
See the
Fuel Kit Installation Guide
for information
about the fuel transducer cable.
Wire the power cable for Auto power (as de-
scribed in this section) to make sure the fuel
counter starts as soon as the engine starts.
For twin engine installation a T-connector needs
to be installed on the fuel transducer cable.

connect the Fishfinder to other NMEA instru-
ments such as Navman’s REPEAT 3100. (See
section 6-6 Systems of several instruments.)
NMEA-1 in: Blue wire – Use this, if desired, to
connect a NMEA instrument to the Fishfinder
such as an external GPS source. Note however,
to use NMEA-1 in, NavBus must be disabled
in the Comms menu – see section 3-7 Setup
> Comms.
NavBus wiring option:
NavBus (-): Blue wire: and;
NavBus (+): Orange wire: Use this, if desired, to
connect the fishfinder to other Navman instru-
ments such as Navman’s REPEAT 3100. (See
section 6-6 Systems of several instruments.)
NMEA and NavBus option:
If both NMEA and NavBus are to be used, then
use the following:
NMEA out: White wire - NMEA out
NMEA in: NMEA-2 in (White connector)
