INSTALLATION INSTRUCTIONS
Marine Network Wiring and Cables
Garmin Marine Network components use specialized Garmin Network cables. For some installations, it may be necessary to drill 1.25" (31.7
mm)holes to route the connector end of the cables. Garmin rubber grommets are provided to cover the installation holes (see below). Wiring instructions are found on the following pages. If you experience difficulty installing the unit, contact Garmin Product Support or seek the assistance of a professional installer.
The grommets may not be needed in some installations. The grommets do NOT create a waterproof seal. Apply a marine sealant after installation to weatherproof around the grommet and cable. Additional grommets can be purchased from your Garmin dealer or direct from Garmin. Be sure to test the system before installing the grommets.
