The Fishfinder 340C can be connected to another piece of NMEA 

compatible electronic equipment, such as a Garmin GPS (Global 

Positioning System). If equipped with a capable transducer, the 

Fishfinder 340C receiver can send depth, temperature, and speed 

information. It can also mark a location (see page 41) that can be 

displayed on another device and can accept GPS navigational data, 

such as position, time, course, or distance. Refer to the wiring 

diagram for interfacing the Fishfinder 340C with other devices (see 

page 18).

1.  Follow the voltage source installation steps (see page 15). 

For Garmin units, the ground (Black) wires serve as data 

ground and must be attached together or on the same 

terminal. Refer to the wiring diagram of your GPS unit for 

wire identification.

2.  Connect the Blue (Data OUT) wire from the Fishfinder to the 

Data IN wire on the GPS/NMEA harness.

3.  Connect the Brown (Data IN) wire from the Fishfinder to the 

Data OUT wire on the GPS/NMEA harness.

4.  Set the Fishfinder 340C NMEA Input/Output to 

On (page 

41). For Garmin GPS units, set the communications 

interface to 

NMEA/NMEA, NMEA In/NMEA Out, or NMEA.
