Power Cable Extensions
Connecting the power cable directly to the battery is
recommended. If it is necessary to extend the cable, the
appropriate gauge of wire must be used for the length of the
extension.
You must use crimp connectors and heat-shrink to create a
water-resistant connection.

Grounding the Radar
The radar (and voltage converter, if applicable) must be
connected to the appropriate type of ground using a 3.31 mm²
(12 AWG) copper wire (not included).
1
Route a 3.31 mm² (12 AWG) copper wire to a water ground
location and to the radar pedestal.
2
Connect the wire to the ground connector on the pedestal
( ) using the pre-installed crimp connector.
3
Coat the ground screw and crimp connector with marine
sealant.
4
Connect the other end of the wire to the water ground
location on the boat, and coat the connection with marine
sealant.
5
Select an option:
• If your radar was not packaged with a voltage converter,
no further grounding is necessary.
• If your radar was packaged with a voltage converter,
proceed to step 6.
6
Route a different 3.31 mm² (12 AWG) copper wire to water
ground location and to the voltage converter.
7
Loosen a screw on one corner of the voltage converter and
secure the copper wire to the screw.
8
Coat the screw and wire on the voltage converter with marine
sealant.
9
Connect the other end of the wire to the RF ground location
on the boat, and coat the connection with marine sealant.
Garmin Marine Network Considerations
This device connects to Garmin Marine Network devices to
share radar data with compatible devices on the network. When
connecting to a Garmin Marine Network device, observe these
considerations.
• A Garmin Marine Network cable must be used for all Garmin
Marine Network connections.
◦ Third-party CAT5 cable and RJ45 connectors must not be
used for Garmin Marine Network connections.
◦ Additional Garmin Marine Network cables and connectors
are available from your Garmin dealer.
• Although it is not recommended, you can use a field-
installable connector to create a custom-length Garmin
Marine Network cable if necessary. Follow the directions
provided with the connector.
Radar Operation
All functions of this radar are controlled with your Garmin
chartplotter. See the Radar section of your chartplotter's manual
for operating instructions. To download the latest manual, go to
Software Update
You may need to update the device software when you install
the device or add an accessory to the device.
The software update requires either a Garmin memory card
reader accessory or another Garmin chartplotter connected over
the Garmin Marine Network.
Loading the New Software on a Memory Card
1
Insert a memory card into the card slot on the computer.

Updating the Device Software
Before you can update the software, you must obtain a
software-update memory card or load the latest software onto a
memory card.
1
Turn on the chartplotter.
2
After the home screen appears, insert the memory card into
the card slot.
NOTE:
In order for the software update instructions to
appear, the device must be fully booted before the card is
inserted.
3
Follow the on-screen instructions.
4
Wait several minutes while the software update process
completes.
5
When prompted, leave the memory card in place and restart
the chartplotter manually.
6
Remove the memory card.
NOTE:
If the memory card is removed before the device
restarts fully, the software update is not complete.
Specifying the Antenna Size
Before you can use the radar on your system, you must specify
the antenna size.
You must mount the radar, connect it to power, and connect it to
the Garmin Marine Network before you can specify the antenna
size.
1
Turn on the radar and all devices connected to the Garmin
Marine Network.
An antenna-selection prompt appears on the connected
chartplotters.
NOTE:
If the entire system is being turned on for the first
time, the antenna-selection screen is part of the initial setup
process.
2
Select the installed antenna size for each open-array radar
installed on the boat.
TIP:
If you need to specify a different antenna size, while
viewing the radar screen for the radar you want to change ,
select
Menu
>
Radar Setup
>
Installation
>
Antenna
Configuration
>
Antenna Size
, and select the antenna size.
Front-of-Boat Offset
The front-of-boat offset compensates for the physical location of
the radar scanner on a boat, if the radar scanner does not align
with the bow-stern axis.
