Caution: The G-DEK is designed for vessels with a 12 volt
negative ground electrical system only!
Referring to the connections diagram:
1. Connect the Yellow wire directly to the positive terminal of
the vessel’s battery, or to a point that has +12 volt available
at all times. This lead maintains the memories within the
G-DEK and is the main power source for the unit.
2. Connect the Red wire to the vessel’s +12 volt supply via
an appropriate isolating switch or circuit breaker. This lead
enables the radio to be switched ON and OFF. Alternatively,
this wire can be connected directly to the battery’s positive
terminal and the G-DEK switched ON and OFF using its

G-DEK INSTRUCTION MANUAL PAGE 15
IMPORTANT: Your G-DEK is able to maintain its memories
when it is switched off by the button by drawing power
directly from your battery via the Yellow ‘MEMORY B+’ lead.
Although the memory backup current is very small (about 20
mA) it could eventually discharge your battery if left connected
indefinitely. The time taken to completely discharge your battery
could vary depending on its amp-hour rating and battery
condition.
If you do not run your boat’s motor regularly or your battery is
not kept charged between outings (e.g. solar or wind charger),
we recommend you disconnect the Yellow lead each time you
secure or trail your boat. This is easily done by connecting the
Yellow ‘MEMORY B+’ lead via a master switch, which can be
switched off after each outing. This will mean you will lose all
your preset station memories and clock settings.
The blue (auto antenna) wire on the wiring loom supplies
12 volts when the G-DEK is switched on and can be used to
turn on an external device whenever the G-DEK is switched on.
SPEAKER CONNECTIONS
CAUTION: The G-DEK is a four-speaker system that requires
two separate wires for each speaker. Do not touch the speaker
wires together or allow them to touch other wiring.
A range of GME speakers are available from your local GME retailer.
When connecting the speakers, observe the correct polarity
as shown in the connections diagram on page 13. Incorrect
polarity will result in a reduction of bass response and stereo
effect. The use of speakers with an impedance of less than 4
Ohms is not recommended, as they will cause excessive loading
of the G-DEK’s output circuit and may result in the radio
overheating.
Connect all four speakers as shown in the connections diagram.
Adjust the Fader control for the required front/rear balance. If
you wish to connect only two speakers, connect these to the
rear speaker wires. The remaining speaker wires should be
insulated to ensure they cannot short circuit together or to the
vessel’s 12 volt or negative electrical Bus. If using only two rear
speakers, adjust the Fader control to the rear speakers.
ANTENNA CONNECTIONS
The G-DEK includes an AM/FM tuner (the GM550 also includes
a DAB receiver). As these operate on different frequency bands,
a separate antenna is required for each. For information on
suitable AM/FM and DAB antennas, contact your nearest GME
dealer.
Connect the AM/FM antenna to the larger antenna socket
(bayonet connector). The DAB antenna connects to the smaller
SMA socket (GM550).
AM/FM ANTENNA SOCKET (BAYONET)
DAB ANTENNA SOCKET (SMA)
AUXILIARY INPUTS
There are two auxiliary inputs to allow connection of audio/
video from other external sources. Auxiliary input selection is
made using the button on the remote head unit.
•Aux 1: The auxiliary 1 input accepts an audio input via a
3.5 mm phono connector. This connector is located under
the cover to the left of the USB input socket. The Aux 1 input

G-DEK INSTRUCTION MANUAL PAGE 16
allows the connection of generic MP3 or other audio media
players. The selection and playback of your media files is
controlled by the connected media player.
For best audio performance, set the volume on your media
player to its mid-volume point then adjust it as necessary to
achieve an output volume consistent with the volume level
of the G-DEK’s AM/FM radio. If the output from the media
player sounds distorted, reduce its volume level until the
distortion has gone.
•Aux 2: The auxiliary 2 input accepts low level audio from a
CD, DVD player, digital set top box or similar device. The left
and right audio channels from the device should connect to
the G-DEK’s left and right AUX 2 input leads. If the device is
a DVD player or set top box, connect the video output from
the device to the G-DEK’s video input lead. The G-DEK’s video
output lead should be connected to the video input of a
television or LCD monitor.
In this way, both video and audio from the device will be
selected automatically whenever the AUX 2 input is selected.
The selection and playback of your media files is controlled
by the connected Media Player.
NOTE: For the Aux 1 input, GME offers a custom interface
cable for personal MP3 player connections; Part # LE68. When
using this cable, it is necessary to use the functions on the
portable device to control play.
MICROPHONE/PA CONNECTION
The G-DEK accepts a microphone input via the 3.5 mm
connector fly lead extending from the rear panel. This provides
a Public Address (PA) function for making voice announcements
over the speaker system and is useful in situations found in
commercial vessels or public transport vehicles. A suitable
plug-in microphone MC517BPA is available through your GME
dealer.
REMOTE HEAD CONNECTIONS
Up to two separate remote heads can be connected to
the G-DEK to allow control from two separate locations. If
connecting only one control head, it can be connected to either
remote head socket.
LOW LEVEL OUTPUTS
The G-DEK provides low level audio outputs for both front and
rear channels. These can be used to feed audio to a separate
high powered amplifier system for installations that require
increased output power.
SUB WOOFER OUTPUT
A Sub Woofer output allows the connection of a separate active
Sub Woofer for a superior bass response. If a Sub Woofer is
connected the Sub Woofer output should be enabled through
the ‘Sub Woofer’ option in the menu.
RESET BUTTON
When the installation is complete, it is recommended to press
the Reset Button using a paper clip or similar object (the reset
button is under the lid to the right of the SD card slot). This will
ensure the G-DEK is ready to operate for the first time. If at
any time the controls do not seem to work (after replacing the
vessel’s battery for example), press the Reset Button to reset
the microcomputer inside the G-DEK.
