Mounting Considerations

CAUTION

When exposed to high ambient temperatures and after extended use, the rear of the unit's housing can become hot enough to be painful to touch. To avoid potential personal injury, install the unit in a location where only the front is accessible to users, and the rear of the unit cannot be touched during use.

READ THIS

This unit must be mounted in a location that is not exposed to extreme temperatures or conditions. The temperature range for this unit is listed in the product specifications. Exposing the unit to temperatures outside the specified temperature range, during storage or use, can cause unit failure. Damage caused by extreme temperatures and their consequences is not covered by the warranty.

• Mount the stereo on a flat surface.
• Mount the unit in a location with adequate ventilation to prevent it from overheating.
• When properly mounted using optional marine sealant, the stereo is water-resistant from the front. The connectors on the rear are not water-resistant, so do not mount the stereo in a location where the rear may be submerged or regularly exposed to water.
• If mounting the stereo in a location that may be exposed to water from time to time, mount it within 45 degrees below or 15 degrees above the horizontal plane.
• If mounting the stereo in a location that may be exposed to water from time to time, install a drip loop on the wiring so water can drip from the wiring to prevent damage to the stereo.
• If you must mount the stereo externally on a boat, mount it in a location well above the waterline, where it will not be submerged in water and will not be damaged by docks, pilings, or other equipment.
• Mount the stereo at least 40 cm (15.75 inches) from a magnetic compass to avoid interference.

Mounting the Stereo

READ THIS

Do not use the stereo as a template when drilling mounting holes, as this can damage the screen and void the warranty. Use only the supplied template to drill the mounting holes correctly.

Be careful when cutting the hole to mount the stereo. There is only a small clearance between the housing and the mounting holes, so if you cut the hole too large, it may affect the stability of the stereo when mounted.

Do not apply grease or lubricant to the screws when securing the stereo to the mounting surface. Grease or other lubricants may cause damage to the stereo housing.

Before you can mount the stereo in a new location on the mounting surface, you must select the location considering the mounting conditions.

1. Attach the template to the mounting surface.
2. Drill a hole in the corner of the dashed line on the template.
3. Cut out the mounting surface ① along the inside of the dashed line on the template.
4. Ensure the mounting holes on the stereo align with the pilot holes on the template.
5. Use the correct size drill bit for your mounting surface and screw type, and drill the pilot holes.
6. Remove the template from the mounting surface.
7. Do one of the following:
   • If installing the stereo in a dry location, place the included mounting gasket 2 on the rear of the stereo.
   • If installing the stereo in a location exposed to water, use silicone marine sealant on the mounting surface around the cutout.

READ THIS

Do not install the included mounting gasket if you used sealant on the mounting surface. Using sealant and the mounting gasket may reduce water resistance.

8. If you will not have access to the rear of the stereo after mounting, make the necessary cable connections.
9. Secure the stereo to the mounting surface using the included screws 3. Hand-tighten the screws to avoid over-tightening them.
10. Snap the mounting covers 4 into place.

Port Identification

For the stereo to function correctly, you must connect it to power, speakers, and input sources. Plan your stereo, speaker, and input source setup carefully, including optional NMEA 2000 networks, Fusion PartyBus networks, Garmin BlueNet networks, or older Garmin Marine Network before making any connections.

Wiring Harness and Connector Identification

[Diagram showing wiring harness connections]

Cable or RCA Connector Function

Connecting to Power

When connecting the stereo to power, connect the yellow, red, and black wires to the power source. The yellow and red wires have different functions, and the method you use to connect them to power depends on how you plan to use the stereo on the vessel.

Yellow Wire

• This wire supplies power to the stereo.
• This wire should be connected via a 25 A circuit breaker if one is available on the vessel. WARNING If a 25 A circuit breaker is not available on the vessel, connect this wire to power via a 25 A fuse (not included). Connecting this wire to power without a circuit breaker or fuse can lead to a short circuit in the wire, which can cause overheating and a possible fire.
• This wire supplies power to the stereo at all times, and drains the battery even when the stereo is not in use. Install a manual switch on this wire if a 25 A circuit breaker is not available on the vessel, or if you cannot switch the breaker on and off to turn off power to the stereo when the vessel is stored.
• When extending this wire, the required wire gauge depends on the length of the extension and the connected power source (Wire Gauge for Power Cable, page 9).

Red Wire

• This wire can be connected to the same power source as the yellow wire using the ignition or a manual switch. This allows you to automatically turn the stereo on and off when you turn the vessel off and on, or when you activate the switch.
• If you use this wire to turn the stereo on and off, it functions the same way as when you use the stereo's power button to turn it off and on. It is not necessary to connect this wire through the ignition or manual switch if you plan to turn the power on and off using the stereo's power button or a connected chartplotter or remote control. Instead, it can be connected to the yellow wire. This wire must be connected to turn on the stereo.
• When you turn off the stereo using this switch or the power button, it enters standby mode, which allows the stereo to start up faster than if you turn off the power using the yellow wire. While in standby mode, the stereo uses up to 350 mA, and you must turn off power to the stereo on the yellow wire using the circuit breaker or manual switch when you are not using the vessel to avoid draining the battery.
• If it is necessary to extend this wire, use a 22 AWG (0.33 mm²) wire.

Black Wire

• This is the ground wire, and you must connect it to the negative pole of the power source or to a common ground.
• When extending this wire, the required wire gauge depends on the length of the extension and the connected power source (Wire Gauge for Power Cable, page 9).

Wire Gauge for Power Cable

The wire gauge needed to connect the stereo to power and ground depends on the power source and the length of the wire run from the power source to the stereo. Refer to this table to find the correct wire gauge for your installation. This is a table of terminal connection resistance.

NOTE: If using aluminum wires, use a wire two gauges larger than the dimension listed below to compensate for any voltage drop due to wire material.

Connecting to Power Without Using the Ignition Switch

This connection method is most often used on larger vessels and on vessels with multiple networked stereos and other marine devices. For these installations, a faster startup time is usually less critical, and it is more efficient to use the circuit breaker or a dedicated switch on the electrical panel to turn off the stereo and ensure no unexpected power interruptions occur.

[Diagram showing power connection without ignition switch]

Route all wires to the stereo's wiring harness, circuit breaker or switch, and power source as needed. Do not connect the wire connector to the stereo until all bare wire connections are made. Install all necessary fuses on the red and yellow wires. Connect the wire connector to the stereo.

Connecting to Power Using an Ignition Switch

This connection method is most often used on waterski boats, wake boats, and similar sport or recreational boats where engine power is frequently switched on and off. For these installations, a quick standby and faster startup time are desirable, so music can be stopped and restarted as quickly as possible after the engine is restarted. In standby mode, the stereo uses up to 350 mA, and you should connect the power wires through a circuit breaker or a manual switch to avoid draining the battery when not using the boat.

[Diagram showing power connection with ignition switch]

Route all wires to the stereo's wiring harness, ignition or ACC switch, circuit breaker, and power source as needed. Do not connect the wire connector to the stereo until all bare wire connections are made. Install all necessary fuses on the red and yellow wires. Connect the wire connector to the stereo.

Speaker Zones

You can group speakers in an area into one speaker zone. This allows you to control the volume for the zones individually. For example, you can lower the volume in the cabin and raise the volume on deck.

The speaker wiring on the wiring harness for zones 1 and 2 is driven by the onboard amplifier. If you want to use the RCA line outputs and RCA subwoofer outputs for zones 1 and 2, you must connect external amplifiers.

Zones 3 and 4 are only available as line-level outputs. If you want to use the RCA line outputs and RCA subwoofer outputs for zones 3 and 4, you must connect external amplifiers.

You can set balance, volume limit, tone, subwoofer frequency, and name for each zone and configure other zone-specific settings.

NOTE: The subwoofer frequency cannot be adjusted when handled by the DSP.

[Diagram showing single-zone speaker wiring example]

Stereo Wiring with Line Output

This diagram shows a system installation with an external amplifier and subwoofer connected to zone 2 on the stereo using a line output. You can connect an amplifier and subwoofer to any or all of the available zones on the stereo.

NOTE: You can connect speakers to the speaker wires for the internal stereo amplifier while using the line output for zone 1 and 2, even though adjusting the volume will affect both the speakers connected to the internal amplifier and the line output. This may result in uneven volume levels.

[Diagram showing stereo wiring with line output]

NMEA 2000 System Wiring Diagram

[Diagram showing NMEA 2000 system wiring]

Audio Return Channel

With Audio Return Channel (ARC), you can play digital audio from a TV or other source with HDMI technology through the stereo's speakers.

HDMI cables with version 1.4 or higher support ARC. When planning your stereo installation, check if your devices and cables support ARC. Most devices that support ARC have an ARC label on the HDMI connector that supports ARC.

You may need to configure your TV or other source to output audio via ARC. This stereo supports ARC (but not eARC), CEC 1.4, and PCM stereo audio. You can find a configuration guide in the source device's owner's manual.

NOTE: There is a length limitation for the HDMI cable when using the ARC function. If the source is more than 5 m (16 ft) away from the stereo, confirm with the cable manufacturer that it can support ARC at the required length.

TIPS: On compatible TVs, you can control the stereo volume with the TV remote control when using the ARC source.

Configuring the Antenna Ports for DAB and FM Antennas

NOTE: These instructions apply only to European models. DAB stations broadcast only in selected areas of Europe, so not all models support this feature.

There are two antenna ports on the stereo, and you can connect a DAB antenna and an FM antenna to one of them, depending on the antenna's connector type. After connecting an antenna, you must configure the stereo to use the antenna correctly.

1. Select > Settings > Source > DAB.
2. Select an option:
   • If you are configuring an antenna port for a DAB antenna, select DAB antenna:.
   • If you are configuring an antenna port for an FM antenna, select FM antenna.
3. Select the antenna port to which you connected the antenna.
4. Repeat these steps for the other antenna if necessary.
5. If the connected antenna requires power from the stereo, select > Settings > Source > DAB and select Antenna 1 power or Antenna 2 power, depending on which port you connected the antenna to (accessories).

Fusion PartyBus Network

The Fusion PartyBus network feature allows you to connect multiple compatible stereos together in a network using a combination of wired or wireless connections.

NOTE: When connecting a Fusion stereo to a Garmin BlueNet network or Garmin Marine Network, you can only use Garmin and Fusion devices. You may not be able to use routers, storage devices, or other third-party network products directly with this stereo.

TIPS: When the stereo is connected to a Garmin BlueNet network or Garmin Marine Network, you can connect a mobile device to a wireless access point on a connected Garmin chartplotter, and control the stereo via the Fusion Audio app.

You cannot use Wi-Fi® network management when a stereo is connected to a Garmin network.

You can group a compatible stereo, such as the Fusion Apollo RA800, with other compatible stereos connected to the Fusion PartyBus network. Grouped stereos can share available sources and control media playback on all stereos in the group, providing a synchronized audio experience throughout the vessel. You can quickly create, edit, and deactivate groups as needed via compatible stereos or remote controls on the network.

NOTE: A zone stereo, such as the Fusion Apollo SRX400, can create or join a group to control and play sources from other stereos, but it cannot share its sources with the group. For more information on sharing sources, refer to the owner's manual.

You can use compatible stereos and remote controls, whether they are grouped or not, to adjust the volume for available speaker zones on any stereo in the network.

You can wirelessly connect up to eight Fusion PartyBus stereos to a network.

Considerations for Wired Networking

When planning your network installation, consider the following for all wired connections.

• This unit uses Garmin BlueNet technology for wired network connections. For more information on Garmin BlueNet technology, including best practices for building a network with both Garmin BlueNet devices and older Garmin Marine Network devices, go to garmin.com/manuals/bluenet.
• If you connect this stereo to another stereo or device with a Garmin BlueNet network port, you can use standard Garmin BlueNet cables (not included).
• If you connect this stereo to another device that uses older Garmin Marine Network cables, you should use a Garmin Marine Network to Garmin BlueNet network adapter cable (010-12531-11 or 010-13094-00, not included).
• If you connect this stereo to another stereo or device that uses a standard Ethernet port, you should use an RJ45 to Garmin BlueNet network adapter cable (010-12531-02, not included).
• If you use multiple chartplotters that use a mix of Garmin BlueNet network and older Garmin Marine Network connections, you should connect this unit to a Garmin BlueNet chartplotter or switch for best performance.
• For more information on Garmin BlueNet technology, go to garmin.com/manuals/bluenet.
• You can use a single network cable to connect the stereo directly to a compatible device.
• You must use wired network switches and wired or wireless network routers when connecting more than two compatible devices to a network.
• If you install a router on the network, it should be configured as a DHCP server by default. Refer to your router instructions for more information.
• If you do not install a router and there are no other DHCP servers on the network, you should configure one Fusion PartyBus stereo as a DHCP server (Setting the Fusion PartyBus Unit as a DHCP Server, page 23).

Wired Network Example for Direct Connections

You do not need to change network settings when connecting two devices directly, but for best results, you should configure one device as a DHCP server (Setting the Fusion PartyBus Unit as a DHCP Server, page 23).

[Diagram showing wired network for direct connections]

Wired Network Example with Switch or Router

You must use wired network switches, a wired network router, or both to connect more than two devices.

If you have more than two devices using Garmin BlueNet network technology, you can use a Garmin BlueNet 20 switch to connect them.

If you have not installed a router and there are no other DHCP servers on the network, you should configure one Fusion PartyBus stereo as a DHCP server (Setting the Fusion PartyBus Unit as a DHCP Server, page 23). If you have installed a router, you may need to configure it as a DHCP server. Refer to your router instructions for more information.

[Diagram showing wired network with switch or router]

Considerations for Wireless Networks

When setting up the network, consider the following for all wireless connections.

• Wired connections are more reliable than wireless connections. You should set up a network with network cables, but if that is not possible, many Fusion PartyBus devices are Wi-Fi compatible. You can connect them to wireless routers or access points.
• If you install a wireless router on the network, it should be configured as a DHCP server by default. Refer to your wireless router instructions for more information.
• If you do not use a wireless router, you can configure this unit as a wireless access point, allowing you to connect other devices within wireless range.
• NOTE: You should not configure this unit as a wireless access point if you have installed a router on the network, as it may cause DHCP conflicts and lead to poor network performance.
• If you connect a Fusion PartyBus unit to the network as a WI-FI CLIENT, you cannot connect other wired Fusion PartyBus units to that unit.
• You can connect a smartphone to the wireless network to control all stereos in the network using the Fusion Audio app.
• You can connect an Apple device to the wireless network to stream media to multiple stereos on the network using Apple AirPlay® 2.
• If you connect a Bluetooth® device to the stereo, it may interfere with some Wi-Fi connections.
• Wi-Fi signals can interfere with Bluetooth device connections. You should turn off the Wi-Fi setting on the stereo if you are not using it to connect to a wireless network or as a wireless access point.

Setting Up a Network

You should have basic knowledge of networking to build a network for Fusion PartyBus devices. This guide provides basic information on building and configuring a network, and applies to most situations. If you need to perform advanced networking tasks, such as assigning static IP addresses to devices on the network or configuring advanced settings on a connected router, you may need to consult a network specialist.

1. Determine where the Fusion PartyBus devices you want to connect to the network will be installed. NOTE: Wired connections are more reliable than wireless connections. When planning the network, run network cables instead of using wireless connections whenever possible.
2. Determine where all necessary network routers or switches will be installed.
3. Run the network cable to the installation locations for the stereos, switches, and router. NOTE: If you are only connecting this stereo to other stereos or devices with a Garmin BlueNet network port, you can use Garmin BlueNet cables instead of Cat5e or Cat6 cables. If you are connecting to other stereos or devices with a standard RJ45 network port, you must use an RJ45 to Garmin BlueNet adapter cable (010-12531-02, not included) to connect a Cat5e or Cat6 cable to this stereo.
4. Connect the network cables to the stereos, switches, and router. READ THIS Do not complete the stereo installation yet. Test the network before installing the stereos.
5. Turn on all devices connected to the network, including wireless devices.
6. Choose an option:
   • If you are using a network router (wired or wireless), refer to the documentation that came with the router to configure the router as a DHCP server, if necessary. When using a router as a DHCP server, all stereos on the network should use the default configuration (DHCP client).
   • If you are not using a wireless router, configure one stereo as a wireless access point (Setting the Fusion PartyBus Unit as a Wireless Access Point, page 24), if necessary. If you configure a stereo as a wireless access point, that stereo becomes the DHCP server, and all other stereos on the network should use the default configuration (DHCP client).
   • If you are not using a network router, not using a stereo as a wireless access point, and there are no other DHCP servers on the network, you should configure one of the stereos as a DHCP server (Setting the Fusion PartyBus Unit as a DHCP Server, page 23).
7. Test the network by selecting > Groups to display a list of devices connected to the network, and choose an option:
   • If a Fusion PartyBus unit is not available on the network, troubleshoot the network (Troubleshooting the Network, page 25).
   • If all Fusion PartyBus units are available on the network, complete the installation for each stereo, if necessary.

Network Configuration

TIPS: You can select the network status icon from any screen to open the network configuration menu.

Setting the Fusion PartyBus Unit as a DHCP Server

If you have connected more than two network devices using a network switch or wireless access point, but have not installed a router, you should configure only one Fusion PartyBus stereo as a DHCP server. READ THIS If you have more than one DHCP server on the network, all devices on the network will be unstable and perform poorly. NOTE: If you have configured this stereo as a WI-FI ACCESS POINT, it is configured as a DHCP server by default, and no further settings changes are necessary (Setting the Fusion PartyBus Unit as a Wireless Access Point, page 24).

1. If the unit is connected to the network via an Ethernet cable, select > Settings > Network > Wi-Fi is available.
2. If the unit is connected to the network via an Ethernet cable, select Static IP > Save.
3. Select Advanced > DHCP server > DHCP enabled > Save.

Connecting the Stereo to a Garmin Network

NOTE: When connecting the stereo to a Garmin BlueNet network or Garmin Marine Network, you can only use Garmin and Fusion devices. You cannot use routers or other third-party network products directly with this stereo.

You cannot use Wi-Fi networks to connect to a Garmin chartplotter, and you also cannot use Wi-Fi networks on the stereo when it is connected to a Garmin chartplotter with a wired network connection.

You can connect this stereo to a Garmin BlueNet network or Garmin Marine Network to display and control it via a compatible Garmin chartplotter.

NOTE: If a Garmin chartplotter is registered on the network, the stereo automatically enters Garmin Marine Network mode, restarts the stereo, and all other network settings are disabled. If this does not happen automatically, you can reset the network settings for the stereo and reconnect it (Restoring Network Settings, page 24). If it still does not happen automatically, restore the stereo's factory settings, and then reconnect it.

This stereo is compatible with both Garmin BlueNet devices and Garmin Marine Network devices. You can connect the stereo to either type of network, but if you have multiple stereos, they should all be connected to one type of network.

NOTE: If the vessel has a combination of Garmin Marine Network and Garmin BlueNet network connected via a Garmin BlueNet bridge, all stereos should be connected to the Garmin BlueNet network for best performance.

For more information on Garmin BlueNet technology, including best practices for building a network with both Garmin BlueNet devices and Garmin Marine Network devices, go to garmin.com/manuals/bluenet.

TIPS: When the stereo is connected to a Garmin network, you can connect a mobile device to a wireless access point on a connected Garmin chartplotter, and control the stereo via the Fusion Audio app.

1. Find out which device on the Garmin BlueNet network or Garmin Marine Network you should connect the stereo to.
2. Choose an option:
   • If you want to connect the stereo to a Garmin BlueNet device, use a Garmin BlueNet cable (not included).
   • If you want to connect the stereo to a Garmin Marine Network device, you can use a Garmin Marine Network to Garmin BlueNet network adapter cable (010-12531-11 or 010-13094-00, not included).

Setting the Fusion PartyBus Unit as a Wireless Access Point

Before you can connect multiple Fusion PartyBus devices or smartphones to a Fusion PartyBus unit wirelessly, you must configure one unit as a wireless access point. This is not necessary if you have a wireless router or another wireless access point installed on the network. READ THIS You should not configure this unit as a wireless access point if you have installed a router on the network. Doing so may cause DHCP conflicts and poor network performance. For more detailed configuration instructions, refer to the owner's manual.

1. Select > Settings > Network > WI-FI ACCESS POINT.

Advanced Network Configuration

You can perform advanced network tasks on a Fusion PartyBus unit, such as defining DHCP ranges and setting static IP addresses. For more information, refer to the owner's manual. NOTE: When the stereo is connected to the Garmin Marine Network via Ethernet and configured as a DHCP client, it automatically registers and connects to the Garmin Marine Network.

Troubleshooting the Network

If you cannot see or connect to Fusion Apollo devices on the network, perform these steps.

• Verify that all Fusion Apollo stereos, remote controls, network switches, routers, and wireless access points are connected to the network and powered on.
• Verify that wireless Fusion Apollo devices are connected to a wireless router or access point on the network. NOTE: Wired connections are more reliable than wireless connections. If possible, connect devices to the network using an Ethernet cable.
• Ensure that only one device, either a stereo or a router, is configured as a DHCP server. If the unit is connected to a Garmin chartplotter using a wired Garmin BlueNet or Garmin Marine Network connection, it acts as the DHCP server for the network, and no connected stereos should be configured as DHCP servers.
• Change the channel on the router or wireless access point to test and correct interference. You may experience wireless interference if there are many wireless access points nearby.
• Disconnect Bluetooth devices to test and correct interference. Connecting a Bluetooth device to a stereo configured as a wireless access point or client may reduce wireless performance.
• If you have configured static IP addresses, ensure that each device has a unique IP address, that the first three sets of numbers in the IP addresses match, and that the subnet mask on each device is identical.
• If you have made configuration changes that may cause network problems, reset all network settings to the factory settings.
• If you connected the Fusion Apollo unit to a Garmin chartplotter using a wired Garmin BlueNet or Garmin Marine Network connection, the network settings on the unit should automatically switch to Garmin Marine Network. If the network settings do not change as expected, you can reset the network settings on the unit (Restoring Network Settings, page 24).
