Garmin GSD 22 Installation Instructions Manual page 5

Marine Network Wiring and Cables
Garmin Marine Network components use specialized Garmin Network cables. For some installations, it may be necessary to drill 1¼ in.
(32 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 GSD 22, 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. To create a waterproof seal, apply
marine sealant around the grommet and cable after installation. Additional grommets can be purchased from your Garmin dealer or direct from
Garmin. Be sure to test the system before installing the grommets.
