Installation Notes

CAUTION: In environments with high temperatures and after intensive use, the back of the device may reach temperatures that are considered dangerous to the touch. To prevent possible personal injury, the device must be installed in a location where only the front panel is accessible to the user, and the back cannot be touched during operation.

NOTICE: Do not install the device in a location subject to extreme temperatures or conditions. The operating temperature range for the device is listed in the product specifications. Prolonged exposure to temperatures exceeding the specified temperature range, under storage or operating conditions, can cause damage to the device. Damage and consequences related to exposure to extreme temperatures are not covered by the warranty.

• The stereo must be installed on a flat surface.
• Install the device in a location with adequate ventilation to prevent heat buildup.
• When installed correctly with optional marine sealant, the stereo is water resistant on the front. The connectors on the back are not water resistant, so the stereo must not be installed in a location where the back may be submerged or frequently exposed to water.
• If the stereo is installed in a location occasionally exposed to water, it must be mounted with a downward tilt between 45 degrees and an upward tilt of 15 degrees from the horizontal plane.
• If the stereo is installed in a location occasionally exposed to water, a drip loop must be created in the wiring to allow water to drain, preventing damage to the stereo.
• If installing speakers outdoors on the vessel, choose a location well above the waterline so they are not submerged or damaged by docks, pilings, or other structures.
• To avoid interference with the HDG, the stereo must be installed at least 40 cm (15.75 in.) from a compass.

Stereo Installation

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

Be careful when cutting the hole for stereo installation. The clearance between the chassis and the mounting holes is minimal, so cutting a hole that is too large may compromise the stability of the stereo after installation.

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

Before installing the stereo in a new mounting location, select a location observing the installation notes.

1. Align the template with the installation surface.
2. Drill a hole in the corner of the dashed line on the template.
3. Cut the installation surface 1 following the inside of the line drawn on the template.
4. Ensure the mounting holes on the stereo align with the reference holes on the template.
5. Using a drill bit compatible with the installation surface and screw type, drill the reference holes.
6. Remove the template from the installation surface.
7. Perform an operation:
   • If installing the stereo in a dry location, place the included mounting gasket 2 on the back of the stereo.
   • If installing the stereo in a location exposed to water, apply marine silicone sealant to the mounting surface around the hole.

NOTICE: Do not install the included mounting gasket if sealant has been applied to the mounting surface. Using both the sealant and the gasket may reduce water resistance.

8. If you cannot access the back of the stereo after installation, make the necessary electrical connections.
9. Secure the stereo to the mounting surface using the included screws 3. Hand-tighten screws when securing the stereo to the mounting surface to avoid overtightening.
10. Install the screw covers 4.

Connection Information

For the stereo to function correctly, you must connect it to power, speakers, and input sources. Before making any connections, you must carefully plan the layout of the stereo, speaker, and input source system, as well as any optional NMEA 2000, Fusion PartyBus, Garmin BlueNet, or previous Garmin Marine Network requirements.

Cable and Connector Function

Power Connection

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

Yellow Wire

• This wire provides power to the stereo.
• This wire must be connected via a 25 A circuit breaker, if available on the boat.

WARNING: If a 25 A circuit breaker is not available on the vessel, you must connect this wire to power via a 25 A fuse (not included). Connecting this wire to power without a circuit breaker or fuse could cause a short circuit in the wire, leading to overheating and possible fire.

• This wire provides power to the stereo at all times and drains the battery even when the stereo is not in use. You must install a manual switch on this wire if the vessel does not have a 25 A circuit breaker or if you cannot activate/deactivate the switch to interrupt power to the stereo when the vessel is not in use.
• When extending this wire, the required gauge depends on the extension length and the connected power source (Power Cable Gauge Guide, page 10).

Red Wire

• This wire can be connected to the same power source as the yellow wire via the ignition switch or a manual switch. This allows the stereo to automatically turn on and off when you turn the vessel on and off, or when you activate the switch. Using this wire to turn the stereo on and off is equivalent to using the stereo's power button to turn it on and off. You do not need to connect this wire to an ignition or manual switch if you plan to turn the power on/off via the stereo's power button or a connected chartplotter or remote, and you can instead tie them together with the yellow wire. This wire must be connected to turn on the stereo.
• Once turned off using this switch or the power button, the stereo enters standby mode and restarts at a faster rate than when turned off via the yellow wire. In standby mode, the stereo consumes up to 350 mA, and you must disconnect power via the yellow wire with a circuit breaker or manual switch to prevent the battery from draining when the vessel is not in use.

WARNING: This wire must be connected to power via a 1 A fuse (not included), regardless of whether it is connected to the ignition or manual switch. Connecting this wire to power without a fuse could cause a short circuit in the wire, leading to overheating and possible fire.

• If you need to extend this wire, use 22 AWG (0.33 mm²) wire.

Black Wire

• This is the ground wire and must be connected to the negative terminal of the power source or a common ground.
• When extending this wire, the required gauge depends on the extension length and the connected power source (Power Cable Gauge Guide, page 10).

Power Cable Gauge Guide

The wire size needed to connect the stereo to power and ground depends on the power source and the length of the wire connecting the power source to the stereo. Refer to this table to determine the appropriate wire gauge for installation. This table accounts for the resistance of terminal connections.

NOTE: With aluminum wire, use wire with a diameter twice the indicated diameter below to compensate for potential voltage drop caused by the wire material.

Power Connection Without Ignition Switch

This connection method is most often used on large vessels and networked stereo or other marine devices. For these installations, a faster startup time is generally less critical, and it is more effective to use the circuit breaker or a dedicated switch on the electrical panel to turn off the stereo and ensure no unexpected current draw occurs.

Refer to the diagram for planning your cable connections.

Diagram showing power connections without an ignition switch.

Route all wires to the stereo wiring harness, manual switch or circuit breaker, and power source as needed.

Do not connect the wiring harness to the stereo until all unsheathed wire connections are complete.

Install all necessary fuses on the red and yellow wires.

Connect the wiring harness to the stereo.

When the circuit breaker or manual switch on the combined yellow and red wires is closed, the stereo is always on. If necessary, you can use the stereo's power button or a connected chartplotter or remote to activate low-power standby mode.

NOTICE: When the vessel is not in use, disconnect power to the stereo using the circuit breaker or manual switch to prevent the battery from draining.

Power Connection via Ignition Switch

This connection method is most often used on ski, pleasure, and other similar recreational vessels, where power to the engines is frequently activated/deactivated. For these installations, a quick standby and faster startup time are necessary, allowing you to interrupt and restart music as quickly as possible after the engine restarts. In standby mode, the stereo consumes up to 350 mA, and power must be connected via a circuit breaker or manual switch to prevent the battery from draining when the vessel is not in use.

Refer to the diagram for planning your cable connections.

Diagram showing power connections via an ignition switch.

Route all wires to the stereo wiring harness, ignition switch or ACC switch, circuit breaker, and power source as needed.

Do not connect the wiring harness to the stereo until all unsheathed wire connections are complete.

Install all necessary fuses on the red and yellow wires.

Connect the wiring harness to the stereo.

When the ignition switch is turned on, the stereo turns on along with other accessory electronic components. When the ignition switch is turned off, the stereo enters low-power standby mode.

NOTICE: When the vessel is not in use for an extended period, disconnect power to the stereo using the circuit breaker or a manual switch on the yellow wire to prevent the battery from draining.

Speaker Zones

You can group speakers in a single speaker zone. This allows you to control the audio level for individual zones. For example, you may want a lower audio level in the cabin and a higher level on deck.

The speaker wiring harness for zones 1 and 2 is powered by the internal amplifier. 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. 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: Subwoofer frequency is not adjustable when managed by the DSP.

Audio Return Channel

Audio Return Channel (ARC) allows you to play digital audio from a TV or other HDMI-enabled device through the audio system speakers. Ethernet HDMI version 1.4 cables support ARC. When installing the stereo system, verify that devices and cables are ARC compatible. Most devices that support the ARC function have ARC or an ARC label on the HDMI connector that supports ARC.

You may need to configure the TV or other source to play audio via ARC. This stereo supports stereo ARC audio (but not eARC), CEC 1.4, and PCM. If necessary, consult the source device manual for configuration instructions.

NOTE: HDMI cable length is limited when using the ARC function. If the source is more than 5 m (16 ft) from the stereo, check with the cable manufacturer to ensure it can support ARC at the required length.

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

Configuring Antenna Ports for DAB and FM Antennas

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

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

1. Select Settings > Source > Dab.
2. Select an option:
   • To configure an antenna port for a DAB antenna, select Antenna DAB.
   • To configure an antenna port for an FM antenna, select Antenna FM.
3. Select the antenna port to which you connected the antenna.
4. Repeat this procedure for the other antenna, if necessary.
5. If the connected antenna requires power from the stereo, select Settings > Source > Dab, then Antenna Power 1 or Antenna Power 2, depending on the antenna connection port (optional).

Fusion PartyBus Network Connection

The Fusion PartyBus networking feature allows you to connect multiple compatible stereos on a network, using a combination of wired and wireless connections.

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

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

Wi-Fi connectivity cannot be used when the 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, allowing for a synchronized audio experience on the vessel. You can quickly create, modify, and split groups as needed from any compatible stereo or remote control on the network.

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

You can use compatible stereos and remotes, grouped or not, to adjust the volume of available speaker zones for any networked stereo system.

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

Wired Network Connection Considerations

When planning a network installation, keep the following in mind for all wired connections.

• This device uses Garmin BlueNet technology for wired network connections. For more information on Garmin BlueNet technology, including best practices for building a network that includes both Garmin BlueNet devices and previous Garmin Marine Network devices, visit the website 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 previous Garmin Marine Network cables, you must 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 must use an RJ45 cable to a Garmin BlueNet network adapter cable (010-12531-02, not included) to connect a Cat5e or Cat6 cable to this stereo.
• If you are using multiple chartplotters with a combination of Garmin BlueNet and previous Garmin Marine Network connections, you must connect this device to a Garmin BlueNet chartplotter or a switch for the best performance.
• For more information on Garmin BlueNet technology, visit garmin.com/manuals/bluenet.
• You can use a network cable to connect the stereo directly to a compatible device.
• You may need to use wired network switches and wired or wireless network routers to connect more than two compatible devices to a network.
• If installing a router on the network, it must be configured as the default DHCP server. For more information, refer to the instructions for your router.
• If you do not install a router and there are no other DHCP servers on the network, you must configure a Fusion PartyBus stereo to act as the DHCP server (Setting up the Fusion PartyBus device as a DHCP server, page 24).

Wired Network Example for Direct Connections

No network setting changes are necessary when connecting two devices directly, but for best results, configure one device as the DHCP server (Setting up the Fusion PartyBus device as a DHCP server, page 24).

• 1 Fusion PartyBus Stereo
• 2 Fusion PartyBus zone stereo or remote control

Wired Network Example with a 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 with a Garmin BlueNet Ethernet port, you can use a Garmin BlueNet 20 switch to connect them. If a router has not been installed and there are no other DHCP servers on the network, you must configure a Fusion PartyBus stereo to act as the DHCP server (Setting up the Fusion PartyBus device as a DHCP server, page 24). If a router has been installed, you may need to configure it as the DHCP server. For more information, refer to your router's instructions.

• 1 Fusion PartyBus Stereo
• 2 Wired network switch, wired network router, or Garmin BlueNet switch
• 3 Fusion PartyBus zone stereo or remote control

Wireless Network Connection Considerations

When planning the network, keep the following in mind for all wireless connections.

• Wired connections are much more reliable than wireless connections. You should plan the network to use 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.

To install a wireless router on the network, it must be configured as the default DHCP server. For more information, refer to the instructions for your wireless router.

If you are not using a wireless router, you can configure this device as a wireless access point, so you can connect other devices in the wireless coverage area.

NOTE: Do not configure this device as a wireless access point if a router is installed on the network, as this could cause DHCP conflicts and poor network performance.

If you connect a Fusion PartyBus device to the network as a WI-FI CLIENT, you will not be able to connect any wired Fusion PartyBus devices to that device.

You can connect a smartphone to the wireless network to control any stereo on 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.

• Connecting a Bluetooth® device to the stereo may interfere with some Wi-Fi connections. Wi-Fi signals can interfere with Bluetooth device connections. You must disable the Wi-Fi setting on the stereo if it is not being used to connect to a wireless network or provide a wireless access point.

Creating a Network

You need basic knowledge of network connections to create a network for Fusion PartyBus devices.

These instructions will provide basic guidance for creating and configuring a network and will apply to most situations. For advanced network connection operations, such as assigning static IP addresses to devices on the network or configuring advanced settings on a connected router, contact a network technician.

1. Establish the installation location for the Fusion PartyBus devices you want to connect to the network. NOTE: Wired connections are much more reliable than wireless connections. During network planning, use network cables instead of wireless connections where possible.
2. Establish the installation location for any necessary routers or network switches.
3. Route network cables to the installation locations of the stereos, switches, and router. NOTE: If you are connecting this stereo only 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 a Garmin BlueNet RJ45 to adapter cable (010-12531-02, not included) to connect a Cat5e or Cat6 cable to this stereo.
4. Connect network cables to the stereo, switches, and router. NOTICE: Do not complete the stereo installation. Test the network before installing the stereos.
5. Turn on all devices connected to the network, including wireless devices.
6. Select an option:
   • If you are using a network router (wired or wireless), refer to the documentation provided with the router to configure it as a DHCP server, if necessary. When using a router as a DHCP server, all stereos on the network must use the default configuration (DHCP client).
   • If you are not using a wireless router, configure one stereo as a wireless access point, if necessary (Setting up the Fusion PartyBus device as a wireless access point, page 25). Configuring a stereo as an access point turns the stereo into a DHCP server, and all other stereos on the network should use their default configuration (DHCP client).
   • If you are not using a network router, nor a stereo as a wireless access point, and there are no other DHCP servers on the network, you must configure one of the stereos as a DHCP server (Setting up the Fusion PartyBus device as a DHCP server, page 24).
7. Test the network by selecting Groups to display a list of devices connected to the network, then choose an option:
   • If one or more Fusion PartyBus devices are not available on the network, troubleshoot network issues (Troubleshooting Network Issues, page 26).
   • If all Fusion PartyBus devices are available on the network, complete the installation of each stereo, if necessary.

Network Configuration

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

Setting up the Fusion PartyBus Device as a DHCP Server

If more than two network devices were connected using a network switch or wireless access point and a router was not installed, you must configure only one Fusion PartyBus stereo as the DHCP server.

NOTICE: The presence of multiple DHCP servers on the network causes instability and poor performance for all devices on the network.

NOTE: If the stereo was set up as a WI-FI ACCESS POINT, it is configured as the DHCP server by default, and you do not need to change the settings (Setting up the Fusion PartyBus device as a wireless access point, page 25).

1. If the device is connected to the network via an Ethernet cable, select Settings > Network > Wi-Fi Off.
2. If the device 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 or Garmin Marine Network, you can only use Garmin and Fusion devices. You cannot directly use third-party routers or other network products with this stereo.

You cannot use Wi-Fi to connect to a Garmin chartplotter, nor use Wi-Fi on the stereo when it is connected to a Garmin chartplotter via a wired network connection.

You can connect this stereo to a Garmin BlueNet or Garmin Marine Network to view and control the stereo using a compatible Garmin chartplotter.

NOTE: If a Garmin chartplotter is detected on the network, the stereo automatically switches to Garmin Marine Network mode, the stereo restarts, and all other network settings on the stereo are disabled. If this does not happen automatically, reset the stereo's network settings and reconnect them (Resetting Network Settings, page 25). If the problem persists, perform a factory reset on the stereo and reconnect it.

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

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

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

SUGGESTION: 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 use the Fusion Audio app to control the stereo.

1. Identify the optimal device on the Garmin BlueNet or Garmin Marine Network to connect the stereo to.
2. Select an option:
   • To connect the stereo to a Garmin BlueNet device, use a Garmin BlueNet cable (not included).
   • To connect the stereo to a Garmin Marine Network device, use a Garmin Marine Network to Garmin BlueNet network adapter cable (010-12531-11 or 010-13094-00, not included).

Setting up the Fusion PartyBus Device as a Wireless Access Point

Before you can wirelessly connect additional Fusion PartyBus devices or smartphones to a Fusion PartyBus device, you must configure one device as a wireless access point. This operation is not necessary if a wireless router or another wireless access point has been installed on the network.

NOTICE: Do not configure the device as a wireless access point if a router is installed on the network. This may introduce DHCP conflicts and cause poor network performance.

For more detailed configuration instructions, refer to the Owner's Manual.

1. Select Settings > Network > WI-FI ACCESS POINT.
2. Select Use Defaults and wait for the device to save network settings. NOTE: After saving the default settings, you can scroll down to the bottom of the Network menu to view the assigned SSID for the access point.
3. Select Settings > Network > Advanced > WI-FI AP SETTINGS > Password and enter a password for the wireless access point. NOTE: When configuring the stereo as a wireless access point, you can also use the wired network connection without changing additional settings. Wired and wireless networks are bridged.

Connecting the Fusion PartyBus Device to a Wireless Access Point

You can connect the device to a wireless access point on a router or to a compatible Fusion PartyBus device on the network. This device can be connected via Wi-Fi Protected Setup (WPS), if this feature is supported by the access point. This device can be connected via Apple Accessory Configuration (WAC) using a supported Apple device.

1. Select Settings > Network > WI-FI CLIENT > SSID. The list of wireless access points is displayed.
2. Select the wireless Fusion PartyBus access point.

2. Select Network > Advanced > Reset > Yes.

Advanced Network Configuration

You can perform advanced network tasks on a Fusion PartyBus device, such as defining DHCP ranges and setting static IP addresses. For more information, consult the Owner's Manual.

NOTE: If connected to a Garmin Marine Network via Ethernet and configured as a DHCP client, the stereo detects the Garmin Marine Network and connects automatically.

Troubleshooting Network Issues

If you cannot view or connect to Fusion Apollo devices on the network, proceed as follows.

• Verify that all Fusion Apollo stereos, remotes, 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 wireless access point on the network. NOTE: Wired connections are much more reliable than wireless connections. If possible, connect devices to the network using an Ethernet cable.
• Verify that only one device, stereo, or router is configured as the DHCP server. If you are connected to a Garmin chartplotter via a wired Garmin BlueNet or Garmin Marine Network connection, it acts as the DHCP server for the network, and no connected stereo should be configured as a DHCP server.
• Change the channel on the router or wireless access point to check for and correct interference. You may experience wireless interference if there are many wireless access points nearby.
• Disconnect Bluetooth devices to check for and correct interference. Connecting a Bluetooth device to a stereo configured as an access point or wireless client can reduce wireless connectivity performance.
• If static IP addresses have been configured, verify that each device has a unique IP address, that the first three sets of IP address numbers match, and that each device's subnet mask is identical.
• If configuration changes have been made that may cause network problems, reset all network settings to their default values.
• If the Fusion Apollo device was connected to a Garmin chartplotter using a wired Garmin BlueNet or Garmin Marine Network connection, the network settings on the device should automatically switch to Garmin Marine Network. If network settings do not change as expected, reset them on the device (Resetting Network Settings, page 25).
