The GHS 10 connects to the transceiver box and to either the Garmin GHS 10 active speaker (included) or a passive speaker (not included). 

When planning the GHS 10 installation, consider the following:

Per FCC law, you must install the GHS 10 in the wheelhouse or an adjacent room.
Install the GHS 10 and the active speaker at least 20 in. (.5 m) from any compass.
Install the active speaker within 48 in. (1.2 m) of the location you mount the bulkhead pass-through plate.
Consult the VHF 300 Series Layout Diagram on 

 to determine how to connect the GHS 10 through a bulkhead to a speaker and to the 

transceiver box.
If the cable is not long enough to reach the GHS 10 mounting location from the transceiver box, extension cables are available in lengths of 

16 ft. (5 m) and 32 ft. (10 m). Install any extensions between the GHS 10 cable and the transceiver box according to the layout diagram on 

When you install the GHS 10 active speaker, if you use the GHS 10 cable to connect the active speaker to the transceiver box, do not 

connect a passive speaker to the GHS 10 cable. Clip and tape the passive speaker wires.

1.  Use the GHS 10 active speaker Flush Mount Template to mount the active speaker. The template is self-adhesive.
2.  Remove the paper backing from the template and adhere it to the bulkhead in a suitable location.
3.  Use a 3

4.  Place the speaker in the cutout.
5.  Ensure that the mounting screw locations align with 

the holes marked on the template. If they do not, 

mark the locations of new pilot holes.

6.  Drill four

transceiver box, use the GHC 10 cable according to 

the layout diagram on 

.

Do not connect a passive speaker to the GHC 10 

cable you use with the active speaker. Clip and tape the two passive speaker wires.
If the GHC 10 cable is not long enough to reach the transceiver box location, install an extension (not included) between the GHC 10 

10. To install the active speaker wiring harness though the bulkhead, follow the procedures on
