Bail Mounting the Device

NOTICE
If you are mounting the bracket on fiberglass with screws, it is recommended to use a countersink bit to drill a clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer when the screws are tightened.

1. Select the mounting hardware appropriate for your mounting surface and for the bail-mount bracket.
2. Using the bail-mount bracket as a template, mark the pilot holes2 .
3. Using a drill bit appropriate for the mounting hardware, drill the four pilot holes.
4. Using the selected mounting hardware, secure the bail-mount bracket to the mounting surface.
5. Place the cradle 3   into the bail-mount bracket, and tighten the bail-mount knobs 4 .
6. Connect all necessary cables to the cradle (Connector View, page 4), and spin the locking rings clockwise to lock the cables to the cradle.

NOTICE
To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps.

Flush Mounting the Device

NOTICE
Be careful when cutting the hole to flush mount the device. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the device after it is mounted.
Using a metal pry tool such as a screwdriver can damage the trim caps and the device. Use a plastic pry tool when possible.
You can mount the device in your dashboard using the flush-mount template and appropriate hardware.

1. Secure the template to the mounting location.

2. Using a 13 mm ( /2 in.) drill bit, drill one or more of the holes inside the corners of the solid line on the template to prepare the mounting surface for cutting. 1 3 Using a jigsaw or rotary cutting tool, cut the mounting surface along the inside of the solid line indicated on the template.

3. Place the device into the cutout to test the fit.

4. Use a pry tool, such as a flat piece of plastic or a screwdriver, to carefully pry up the corners of the trim caps, and remove the trim caps.

5. Place the device in the cutout, and ensure the mounting holes on the device line up with the pilot holes on the template.

6. If the mounting holes on the device do not line up with the pilot holes on the template, mark the new hole locations.

7. Using a 3.2 mm ( /8 in.) drill bit, drill the pilot holes.

8. Remove the template from the mounting surface.

9. Place the device in the cradle (Installing the Device in the Cradle, page 8).

10. Install the rubber gasket 1 on the back of the device.
    The rubber gasket has adhesive on the back. Make sure you remove the protective liner before installing it on the device.

11. Connect all necessary cables (Connector View, page 4), and spin the locking rings clockwise to secure the cables to the cradle before placing it into the cutout.
    NOTICE
    To prevent corrosion of the metal contacts, cover unused connectors with weather caps.

12. Place the device into the cutout.

13. Secure the device to the mounting surface using the included screws.

14. Install the trim caps by snapping them in place around the edges of the device.

Connecting to Power
WARNING
When connecting the power cable, do not remove the in-line fuse holder. To prevent the possibility of injury or product damage caused by fire or overheating, the appropriate fuse must be in place as indicated in the product specifications. Connecting the power cable without the appropriate fuse in place voids the product warranty.
You should connect the red wire to the power source through the ignition or another manual switch to turn the device on and off.
The brown and blue wires on the power cable are not used by this device and should not be connected. You can cut and tape the ends of these wires for a clean install, if preferred.

1. Route the power cable between the power source and the device.
2. Connect the red power wire to the ignition or another manual switch, and connect the switch to the positive (+) battery terminal, if necessary.
3. Connect the black wire to the negative (-) battery terminal or to ground.

Connecting the Device to a Transducer

Go to garmin.com/transducers or contact your local Garmin dealer to determine the appropriate type of transducer for your needs.
NOTE: If you use an existing transducer and the transducer cable pin connector does not match the device port, you may be able to use a transducer cable adapter to connect your existing transducer to this device. Go to garmin.com for more information about transducer accessories.

1. Follow the instructions provided with your transducer to correctly install it on your boat.
2. Route the transducer cable to the back of your device, away from sources of electrical interference.
3. Connect the transducer cable to the appropriate port on the cradle.

If the device behaves erratically, the cable connector may not be fully seated. Disconnect the cable connector from the port, check the pin alignment, and firmly push the connector into the port.

NMEA 2000 Considerations

NOTICE
If you are connecting to an existing NMEA 2000 network, identify the NMEA 2000 power cable. Only one NMEA 2000 power cable is required for the NMEA 2000 network to operate properly.
A NMEA 2000 Power Isolator (010-11580-00) should be used in installations where the existing NMEA 2000 network manufacturer is unknown.
If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery directly.
You can connect your device to a NMEA 2000 network on your boat to share data from NMEA 2000 compatible devices such as a GPS antenna or a VHF radio. The necessary NMEA 2000 cables and connectors are sold separately.
This device is not powered through the NMEA 2000 network. You must connect the device to a power source (Connecting to Power, page 4).
If you are unfamiliar with NMEA 2000, you should read the Technical Reference for NMEA 2000 Products at garmin.com/manuals/nmea_2000.
The port labeled NMEA 2000 on the cradle is used to connect it to a standard NMEA 2000 network

Installing Locking Rings on the Cables

To help make the cable-routing process easier, some locking rings are packaged separately from the cables.
When installing a cable that does not have a locking ring installed at the factory, you must install the split-collar locking ring on the cable to ensure a tight connection.

1. Separate the two halves of the locking ring 1 .
2. Align the two halves 2 of the locking ring over the cable and snap them together.
3.  Insert the O-ring into 3 the end of the connector.
4.  After connecting the cable to the port, turn the locking ring clockwise to tighten it.
