NOTE: When using GPSMAP 2108, please 

use GSD 21 OR GSD 22 as Sonar options.

GPSMAP 2108 is  capable of using Garmin 

network but NOT CANet. Either sonar or radar 

information can be shown at the time when using 

GSD21. Both information can NOT be shown

simultaneously.

 

NOTE: When using GSD 21, please wire to

the NMEA 1 In/Out port of the GPSMAP 2008 

/ 2108. GSD 22 should be wired to CANet

(GPSMAP2008). GSD22 should be hooked to

the network port (GPSMAP 2108). When using 

Garmin Radar and sonar modules, you will need 
a network expander GMS10.

The unit comes with a wiring harness that connects 

the unit to power and the transducer with one easy-to-

remove connection and provides interface capabilities 

for connecting external devices. 
The color code in the diagram (see 

page 41

 for 

GPSMAP2008/2108) indicates the appropriate 

harness connections. The replacement fuse is a 

AGC/ 3AG - 3 Amp fuse. If it is necessary to extend 

the power wires, use 22 AWG wire. DO NOT cut the

transducer cable, because this voids your warranty. 

You can wire the unit directly to the battery. If your 

boat has an electrical system, you might be able to 

wire the unit directly to an unused holder on your 

current fuse block. If you are using the boat’s fuse 

block, remove the in-line fuse holder supplied with 

the unit. 

  CAuTION: The maximum unit input voltage is 

35 Volts DC. Do not exceed this voltage, because

this can damage the unit and void the warranty.
