Garmin gpsmap 4008 User Manual

Appendix

The GPSMAP 4000 and GPSMAP 5000 series chartplotters can accept data from NMEA 0183 

compliant devices and also from certain NMEA 2000 devices connected to an existing NMEA 2000 

network on your boat.

The NMEA 0183 data cable included with the GPSMAP 4000 and GPSMAP 5000 series 

chartplotters support the NMEA 0183 standard, which is used to wire various NMEA 0183-

compliant devices such as VHF radios, NMEA instruments, autopilots, wind sensors, or heading 

sensors.
The GPSMAP 4000 and GPSMAP 5000 series chartplotters can receive data from up to four NMEA 

0183-compliant devices and send GPS data to up to six NMEA 0183-compliant devices.
To wire a GPSMAP 4000 or GPSMAP 5000 series chartplotter to optional NMEA 0183-compliant 

devices, see the GPSMAP 4000/5000 Series Installation Instructions.

GPWPL, GPXTE, and Garmin proprietary sentences—PGRME, PGRMM, and PGRMZ.
This unit also includes support for the WPL sentence, DSC, and sonar NMEA 0183 input with 

support for the DPT (depth) or DBT, MTW (water temp), and VHW (water temp, speed, and 

heading) sentences.

  NOtE: To configure how the unit manages these NMEA 0183 sentences, see 

The GPSMAP 4000 and GPSMAP 5000 series chartplotters are NMEA 2000 certified and can 

receive data from a NMEA 2000 network installed on the boat.
To connect a GPSMAP 4000 or GPSMAP 5000 series chartplotter to an existing NMEA 2000 

network and to see a list of supported NMEA 2000 PGN numbers, see the GPSMAP 4000/5000 

Series Installation Instructions.

 All GPSMAP 4000 and GPSMAP 5000 series chartplotters are NMEA 2000 

certified.
