Software Update
After installation, you may need to update the chartplotter software. For instructions on how to update the software, refer to the manual available at garmin.com/manuals/echomap_ultra_2_16xsv.
Installation Considerations
You can flush mount the device or use the gimbal bracket to mount it to the dashboard. When choosing an installation location, consider the following:
- The installation location must provide a clear view of the screen, and the device's buttons must be easily accessible.
- The installation location must be sturdy enough to support the device and mount.
- The cables must be long enough to connect the components and to the power source.
- To avoid interfering with the magnetic compass, install the device at a safe distance as specified in the compass product specifications.
Installing with the Gimbal Bracket
Note: If you are screwing the bracket into fiberglass, it is recommended to use a countersink drill bit to drill a pilot hole that only penetrates the gelcoat. This will help prevent the gelcoat from cracking when tightening the screws.
You can use the bracket to mount the device to a flat surface using the gimbal bracket.
- Use the gimbal bracket ① as a template to mark the pilot holes ②.
- Drill pilot holes using a 3 mm (1/8 in.) drill bit.
- Attach the gimbal bracket to the surface using the included washers and wood screws ③.
- Attach the gimbal bracket knobs ④ to the sides of the device.
- Place the device in the gimbal bracket and tighten the gimbal bracket knobs.
- Attach the cover by snapping it into place along the edge of the device.
Installing with a Flush Mount
Note: Be careful when cutting the hole for a flush mount. There is very little clearance between the device's case and the mounting hole, and cutting a hole that is too large may compromise the stability of the device after installation.
Using metal prying tools, such as a screwdriver, may damage the cover and device. Use plastic prying tools whenever possible.
You can use the flush mount template and the included screws to mount the device to the dashboard.
- Secure the template to the mounting location.
- Drill one or more holes inside the solid lines on the template corners using an 8.5 mm (11/32 in.) drill bit to prepare the surface for cutting.
- Using a jigsaw or rotary cutting tool, cut inside the solid lines indicated on the template.
- Place the device in the cut hole to test the fit.
- If necessary, use a file or sandpaper to adjust the size of the cut hole.
- Carefully pry up the corners of the cover using a prying tool (such as a flat plastic piece or screwdriver) and remove the cover.
- Place the device in the cut hole, ensuring the mounting holes on the device align with the pilot holes on the template.
- If the mounting holes on the device do not align with the pilot holes on the template, mark new pilot hole locations.
- Drill pilot holes using a 3.2 mm (1/8 in.) drill bit.
- Remove the template from the mounting surface.
- Install the rubber pads ① on the back of the device. The rubber pads have adhesive backing. Ensure you remove the protective film before attaching them to the device.
- Connect all necessary cables (see Connector View, page 2) and rotate the locking rings clockwise to secure the cables to the device before placing the device in the cut hole.
Note: To prevent corrosion of metal surfaces, cover unused connectors with the included moisture covers.
- Place the device in the cut hole.
- Secure the device to the mounting surface using the included screws.
- Attach the cover by snapping it into place along the edge of the device.
Connection Considerations
After connecting the cables to the device, tighten the locking rings to secure each cable.
Connecting to Transducers
Visit garmin.com/transducers or contact your local Garmin dealer to determine the transducer type that suits your needs.
Note: If you are using an existing transducer and the pinout of the transducer cable connector does not match the device's port, you may be able to use a transducer cable adapter to connect your existing transducer to this device. Visit garmin.com for more information on transducer accessories.
- Follow the instructions included with the transducer to install it correctly on your boat.
- Route the transducer cable to the back of the device, away from sources of electronic interference.
- Align the keyway on the transducer cable connector with the keyway on the 12 PIN XDCR port on the back of the device.
Note: You must align the keyway on the cable connector with the pins in the cable port. Connecting the cable incorrectly can damage the device.
- Push the connector firmly into the port until it clicks into place. If the device does not operate correctly, the cable connector may not be fully seated. Remove the cable connector from the port, check the pin alignment, and push the connector firmly into the port.
Network Connection Considerations and Requirements
You can use the NETWORK port to connect compatible Garmin devices, such as LiveScope transducers, GCV™ sonar modules, or other ECHOMAP chartplotters. This device is not compatible with Garmin BlueNet™ networks or Garmin Marine Network, so do not connect GPSMAP chartplotters or Garmin radar devices.
When connecting compatible devices to the NETWORK port, observe the following considerations and requirements:
- All devices connected to the NETWORK port must be connected to the same ground. If multiple power sources are used between devices, you must connect the grounds from these sources together using a low-resistance connection, or connect them to a common ground bus bar (if available).
- All connections using the NETWORK port must use Garmin network cables.
- You must not use third-party CAT5e or CAT6 Ethernet cables and RJ45 connectors.
- For additional Garmin network cables and connectors, contact your Garmin dealer.
- Although not recommended, you can use field-installable connectors to create custom-length Garmin network cables if necessary. Follow the instructions included with the connectors.
NMEA 2000 Considerations
Note: If you are connecting to an existing NMEA 2000 network, locate the NMEA 2000 power cable. Only one NMEA 2000 power cable is needed for the NMEA 2000 network to operate correctly.
When performing the installation, if you do not know the manufacturer of the existing NMEA 2000 network, you should use the NMEA 2000 power isolator (010-11580-00).
If you are installing an NMEA 2000 power cable, you must connect it to the boat's ignition switch or another switched source. If the NMEA 2000 power cable is connected directly to the battery, the NMEA 2000 devices will drain your battery.
You can connect the device to the NMEA 2000 network on your boat to share data with NMEA 2000 compatible devices, such as GPS antennas or VHF radios. The necessary NMEA 2000 cables and connectors must be purchased separately.
This device is not powered by the NMEA 2000 network. You must connect the device to a power source.
If you are unfamiliar with NMEA 2000, you should read the NMEA 2000 product technical information at garmin.com/manuals/nmea_2000.
The port labeled NMEA 2000 on the device is used to connect it to a standard NMEA 2000 network.

HDMI Output Video Considerations
Note: To prevent corrosion from moisture, you must use a Garmin accessory cable when connecting the chartplotter to a video display. Using a different cable will void your warranty.
The ECHOMAP Ultra 2 16xsv chartplotter model has an HDMI output feature that can duplicate the chartplotter screen on another device (such as a TV or monitor). The Garmin HDMI accessory cable is 4.5 meters (15 feet) long. If you need a longer cable, you should use an active HDMI cable only. You will need an HDMI coupler to connect two HDMI cables. You must perform all cable connections in a dry environment.
