Garmin 190-01030-02 Manual De Usuario

The GXM 51 is packaged with a NMEA 2000 T-connector and a NMEA 2000/audio cable. You 

will use these two components to connect the GXM 51 to your existing NMEA 2000 network. 

If you do not have an existing NMEA 2000 network, you will need to install a NMEA 2000 

network on your boat. For more information on NMEA 2000, visit 

.

1.  Determine an appropriate 

location to connect the  

GXM 51 to your existing 

NMEA 2000 backbone.

2.  Disconnect one side of a 

NMEA 2000 T-connector from 

the backbone nearest to the 

location where you want to 

connect the GXM 51 antenna.

  If you need to extend the 

NMEA 2000 backbone, 

connect an appropriate 

NMEA 2000 backbone 

extension cable (not included) 

to the side of the T-connector 

you disconnected.

3.  Connect the included  

T-connector in the NMEA 

2000 backbone.

4.  Route the NMEA 2000 portion 

of the NMEA 2000/audio cable 

from the GXM 51 antenna to 

the top of the T-connector you 

added to your NMEA 2000 

network.

  The 19 ft., 6 in. (6 m) NMEA 2000 portion of the NMEA 2000/audio cable is the maximum 

length for a drop cable as defined by the NMEA 2000 standards. If more cable is needed, 

add an extension to your NMEA 2000 backbone, based on the NMEA 2000 guidelines.

To hear XM Radio through the stereo on your boat, connect the audio adapter cable to the audio 

portion of the NMEA 2000/audio cable and to an audio input on the stereo. Refer to the manual 

provided with your stereo for audio input installation and operation.

To ensure compatibility with the GXM 51, upgrade your Garmin chartplotter with the latest 

software. A GPSMAP 4/5000 series chartplotter must be at software v5.0 or later to use the 

GXM 51. For more information, visit
