9.  Route the NMEA 2000/audio cable away from sources of electronic interference, and 

connect it to your NMEA 2000 network and to the audio input of your stereo receiver 

(see 

The GXM 51 can be mounted under a fiberglass surface with the adhesive pads attached to the 

under-deck mounting bracket. The GXM 51 will not acquire satellite signals through metal—

you can only use the under-deck mount under a fiberglass surface.

1.  Determine the location on the 

fiberglass surface where you 

want to mount the GXM 51.

2.  Place the adhesive pads on 

the under-deck mounting 

bracket.

3.  Place the GXM 51 in the 

under-deck mounting bracket.

4.  Adhere the under-deck 

mounting bracket to the 

mounting surface.

5.  Secure the under-deck mount 

to the mounting surface with 

screws. Use extreme care to ensure that the screws do not penetrate the upper surface of 

the deck.

6.  Connect the NMEA 2000/audio cable to the GXM 51.
7.  Route the NMEA 2000/audio cable away from sources of electronic interference, and 

connect it to your NMEA 2000 network and to the audio input of your stereo receiver (see 

step 3 below).
