Notes:
1.
Power and ground wires require 18
AWG.
All other wires require 22
AWG. Use 4-conductor
, shielded wiring for runs over 30’
(9.1 m).
2.
Refer to the GPSMAP
2006/2006C/2010/2010C/3005C/3006C/3010C Installation Instructions for wiring the GPS 17 sensor and other devices.
3.
For runs over 30’
(9.1 m), the drain wire must be connected to the shielding of the extension run. Do not terminate the end of the shield drain wire.
4.
When multiple GPSMAP
3005C/3006C/3010C units are in use, only wire the GSD 20 to one unit.
The GSD 20 information is transmitted to all
units connected to the Garmin Marnine Network.
