GPSMAP 400/500 Series Installation Instructions
Your GPSMAP 400/500 series chartplotter must be properly installed according to the following instructions. You need the appropriate
fasteners, tools, and mounts listed in each section. If you experience difficulty installing the chartplotter, seek the assistance of a
professional installer, or contact Garmin Product Support.
Before installing your GPSMAP 400 or 500 series chartplotter, confirm that the package contains the items listed on the bo

Installing a Transducer Consult the chartplotter feature matrix on page 1 to determine if your chartplotter is capable of using sonar. The following transducer installation procedures are only applicable to sonar-capable chartplotters. Note: The following procedures contain installation instructions for the transducer included with the “s” model GPSMAP 400/500 series chartplotters. If you choose to use a different transducer, installation instructions are provided in the transducer kits. Some

To mount the transducer on a transom: 1. Position the transducer mount at the selected transom location. Make sure the transducer is parallel with the water line. Mark the center locations of each hole on the transducer mount. Apply marine sealant to all screw Mount the transducer threads to prevent water from cable cover far above seeping into the transom. the waterline. The transducer should 1 extend /8 in.

6. Route the transducer cable to the GPSMAP 400/500 series chartplotter using cable ties to secure the cable to the motor shaft. Y ou can fill the forward-facing portion (except the cable tie pocket) of the transducer mount with sealant to avoid accumulating debris. NotIce: Leave some slack in the cable to avoid damage while using the trolling motor . NotIce: Avoid routing the cable close to electrical wires or other sources of electrical interference.

> > Installing the Wiring Harness The chartplotter comes with a wiring harness that connects the chartplotter to power and to optional NMEA 0183 and Garmin CANet devices. If applicable, the wiring harness also connects the chartplotter to a transducer. The wiring harness does not connect to a NMEA 2000 network. For instructions on connecting to a NMEA 2000 network with compatible devices, see page 8. Wire Color Wire Function Red Power (10–32 Vdc*) Ground (power and NMEA 0183) Black NMEA 0183

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 Fishfinder 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 fishfinder to be shared with up to two CANet compa

To test the transom mount transducer installation: 1. Begin testing the installation at a slow speed. If the sonar appears to be working properly , gradually increase the speed of the boat while observing the operation of the sonar . If the sonar signal suddenly is lost or the bottom return is severely degraded, note the speed at which this occurs. 2. Return the boat to the speed at which the signal was lost. Make moderate turns in both directions to see if the signal improves. 1 3. If
