8 GPSMAP 400/500 Series Installation Instructions
Connecting the Wiring Harness to a Garmin CANet Device
If your GPSMAP 400/500 series chartplotter is Garmin CANet-compatible, it can receive sonar information from a CANet-compatible Garmin
Sounder or Fishnder device. See the chartplotter functionality matrix on page 1 to determine whether your chartplotter is CANet compatible.
Using the CANet optimizes the performance of CANet-compatible devices, allowing sonar information from a sounder or shnder to be
shared with up to two CANet compatible Garmin chartplotters. A standard NMEA 0183 connection only allows depth, temperature, and speed
information to be sent to a single chartplotter, whereas a CANet connection provides full sonar readings, including Ultrascroll
™
, so you can
view and control the same information on your compatible chartplotter(s) as you can on your compatible Garmin sounder or shnder.
: To use the Garmin CANet with your device, you must purchase an optional CANet Kit. Contact your Garmin dealer, or visit
www.garmin.com.
Connecting the Chartplotter to a NMEA 2000 Network
If your GPSMAP 400/500 series chartplotter is NMEA 2000-compatible, you can connect it to an existing NMEA 2000 network on your boat
to share information with other connected NMEA 2000-compatible devices. If you do not have an existing NMEA 2000 network on your boat,
you will need to build one. See www.garmin.com for more information.
: NMEA 2000-compatible GPSMAP 400/500 series chartplotters are not packaged with NMEA 2000 connectors or cables. You will need
a NMEA 2000 T-connector and drop cable to connect it to an existing NMEA 2000 network. NMEA 2000 components are available from your
local Garmin dealer or marine dealer.
