Software Update
You may need to update the chart plotter software after installation. For the instructions on how to update the software, see the owner’s manual at garmin.com/manuals/echomap_ultra_2_16xsv.
Mounting Considerations
You can flush mount the device in the dashboard or bail mount the device on the dashboard.
When selecting a mounting location, observe these considerations.
- The mounting location must provide a clear view of the screen and access to the keys on the device.
- The mounting location must be sturdy enough to support the device and the mount.
- The cables must be long enough to connect the components to each other and to power.
- To avoid interference with a magnetic compass, do not install the device closer to a compass than the compass-safe distance value listed in the product specifications.
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.
You can use the bracket to bail mount the device on a flat surface.
- Using the bail-mount bracket as (1) template, mark the pilot holes .
- Using a 3 mm (1 /8 in.) drill bit, drill the pilot holes.
- Secure the bail-mount bracket to the surface using the included washers and wood screws(3).
- Install the bail-mount knobs (4) on the sides of the device.
- Place the device in the bail-mount bracket, and tighten the bail-mount knobs.
- Install the trim caps by snapping them in place around the edges of the device.
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 included screws.
- Secure the template to the mounting location.
- Using a 8.5 mm (11/32 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.
- Using a jigsaw or rotary cutting tool, cut the mounting surface along the inside of the solid line indicated on the template.
- Place the device into the cutout to test the fit.
- If necessary, use a file or sandpaper to refine the size of the cutout.
- 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.
- Place the device in the cutout, and ensure the mounting holes on the device line up with the pilot holeson the template.
- If the mounting holes on the device do not line up with the pilot holes on the template, mark the new hole locations.
- Using a 3.2 mm (1 /8 in.) drill bit, drill the pilot holes.
- Remove the template from the mounting surface.
- Install the rubber gasket (1) on the back of the device.
The individual pieces of the rubber gasket have adhesive on the back. Make sure you remove the protective liner before installing them on the device.
- Connect all necessary cables(Connector View, page 2), and turn the locking rings clockwise to secure the cables to device before placing it into the cutout.
NOTICE:
To prevent corrosion of the metal contacts, cover unused connectors with the attached weather caps. - Place the device into the cutout.
- Secure the device to the mounting surface using the included screws.
- Install the trim caps by snapping them in place around the edges of the device.
Connection Considerations
After connecting the cables to the device, tighten the locking rings to secure each cable.
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.
- Follow the instructions provided with your transducer to correctly install it on your boat.
- Route the transducer cable to the back of your device, away from sources of electrical interference.
- Align the divot on the transducer cable connector with the keying on the 12 PIN XDCR port on the back of the device.
NOTICE
You must align the holes on the cable connector with the pins in the cable port. Misalignment of the cable connection could damage the devices. - Push the connector firmly into the port until fully seated.
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.
Network Connection Considerations and Requirements
You can use the NETWORK port to connect a compatible Garmin device such as a Live Scope transducer,
GCV sonar module, or another ECHOMAP chart plotter. This device is not compatible with the Garmin Blue Net™ network or the Garmin Marine Network, and you should not connect devices such as a GPSMAP chart plotter or a Garmin radar. When connecting a compatible device to the NETWORK port, observe these considerations and requirements:
- Any device connected to the NETWORK port must connect to the same ground as this device. If multiple power sources are used between the devices, you must tie the ground connections from the power supplies together using a low resistance connection or tie them to a common ground bus bar, if available.
- You must use a Garmin network cable for any connections using the NETWORK port.
- You must not use third-party CAT5e or CAT6 Ethernet cable and RJ45 connectors.
- Additional Garmin 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 network cable if necessary. Follow the directions provided with the connector.
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 NMEA2000 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 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.

HDMI Out Video Considerations
NOTICE
To prevent corrosion due to moisture, you must use Garmin accessory cables when connecting the chart plotter to the video display. Using different cables voids your warranty.
The ECHOMAP Ultra 2 16xsv chart plotter models have HDMI out capability to duplicate the chart plotter screen on another device, such as a television or monitor.
The Garmin HDMI accessory cable is 4.5 m (15 ft.) long. If you need a longer cable, you should use an active
HDMI cable only. You need an HDMI coupler to connect the two HDMI cables.
You must make all cable connections in a dry environment.
