Digital Switching
Your chartplotter can be used to monitor and control circuits when connected to a compatible digital switching
system.
For example, you can control the interior lights and navigation lights on the vessel. You can also monitor live
well circuits.
For more information about purchasing and configuring a digital switching system, contact your Garmin dealer.
