Fusion PartyBus Networking
The Fusion PartyBus networking feature allows you to connect multiple compatible stereos together on a
network, using a combination of wired or wireless connections.
NOTE: When you connect a Fusion stereo to Garmin BlueNet
™
network or a Garmin
®
Marine Network, you are
limited to using only Garmin and Fusion devices. You may not be able to use third-party routers, storage devices,
or other network products with this stereo directly.
TIP: When the stereo is connected to a Garmin BlueNet network or a 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.
You can group a compatible stereo, such as the Fusion Apollo RA670 stereo, with other compatible stereos
connected to the Fusion PartyBus network. Grouped stereos can share available sources and control media
playback on all of the stereos in the group, which allows for a synchronized audio experience across the vessel.
You can quickly create, edit, and break up groups as needed from any compatible stereo or remote control on
the network.
You can use compatible stereos and remote controls, whether they are grouped or not, to adjust the volume of
the available speaker zones for any stereo on the network.
You should refer to the installation instructions provided with your remote control when constructing the Fusion
PartyBus network.
Creating a Group
Before you can create a group, you must connect multiple compatible stereos to the Fusion PartyBus network.
See the installation instructions provided with your stereo for information about installing and configuring the
network.
NOTE: There are some limitations and other considerations when using stereos in groups. See Grouped Stereo
Source Considerations, page7for more information.

6 Fusion PartyBus Networking
Grouped Stereo Functions
After you create a group of stereos, additional functions and options are available to all stereos in the group.
• After you create a group, all of the stereos in the group share the same synchronized display.
• You can select a source from any stereo in the group, with a few limitations (Grouped Stereo Source
Considerations, page7), and the source will play simultaneously on all stereos in the group (Selecting a
Source, page4).
• You can control playback (such as pausing and skipping tracks) on any stereo in the group, and it will affect
all stereos in the group.
• You can adjust the volume for any zone on any stereo in the group.
TIP: When adjusting the volume, you can select ALL to adjust the volume of all the stereos in the group at the
same time.
Grouped Stereo Source Considerations
When selecting sources to play over the network, you should observe these considerations.
• You cannot share an AirPlay
®
source with grouped stereos. Using AirPlay 2 software, you can play content on
multiple stereos on the network, but the stereos must not be grouped.
• When audio sources are streamed over a data network, there is a slight delay in the synchronized audio that
may be noticeable if you are also using an external audio source.
◦ If you have a television with an Optical Out connection to a stereo and you continue to use the television
speakers, there will be a delay between the audio from the television speakers and the optical audio
streamed on the grouped stereos.
◦ If you synchronize a radio station and tune that same radio station on a non-networked stereo, there will be
a delay between the audio from the non-networked stereo and the audio from the radio station streamed
on the grouped stereos.
◦ You can remove this delay by changing the GROUP ENABLED setting for the source, but the source cannot
be shared with grouped stereos.
NOTE: You cannot change the settings when a stereo is part of a group. You must remove the stereo from the
group before you can change any settings.
Group Synchronization
By default, groups you create are not maintained when you turn off stereos in the group. If you turn off a single
stereo added to the group, it leaves the group. If you turn off the primary stereo in the group, the group is
dissolved. You can enable group synchronization to preserve group membership for a stereo after turning it off.
Group synchronization behaves differently based on how you turn the stereos off and on.
• If you turn a synchronized stereo off and on by using either the power button on the stereo or a physical
switch on the ignition wire (the red wire), all of the synchronized stereos in the group turn off and on together.
This applies to all of the synchronized stereos in the group, whether or not a stereo is the primary stereo in
the group.
NOTE: Selecting ALL OFF from the power menu on a stereo turns off all stereos on the network, even if they
are not in a group or have group synchronization enabled.
• If you turn a synchronized stereo off and on using a physical switch on the power wire (the yellow wire), the
other synchronized stereos in the group behave differently:
◦ If the synchronized stereo is the primary stereo in the group and you turn it off using a physical switch on
the power wire, the other synchronized stereos in the group remain on, but leave the group. When you turn
the primary stereo back on again, the other synchronized stereos rejoin the group.
◦ If the synchronized stereo is not the primary stereo in the group and you turn it off and on using a physical
switch on the power wire, all of the other synchronized stereos in the group remain on and grouped, and
the stereo rejoins the group when you turn it on again.
Fusion PartyBus Networking 7
Enabling Group Synchronization
You must remove the stereo from an existing group before you can enable the GROUP SYNC setting. You
cannot update settings when a stereo is part of a group.
You must enable this setting on each stereo that you want to retain group settings after a power cycle.
1 Select > SETTINGS.
2 Select the name of the stereo.
3 Select POWER OPTIONS > GROUP SYNC.
The stereo retains group settings after a power cycle.
4 Repeat for additional stereos as needed.

More Information 11
Network Troubleshooting
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 turned on.
• Verify that only one device, either a stereo or a router, is configured as a DHCP server. If you are 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 stereo should be configured as a DHCP server.
• Change the channel on your router or wireless access point to test for and correct interference.
You may experience wireless interference if there are many nearby wireless access points.
• Disconnect Bluetooth devices to test for and correct interference.
Connecting a Bluetooth device to a stereo configured as a wireless access point or client may reduce
wireless performance.
• If you configured static IP addresses, verify that every device has a unique IP address, that the first three sets
of numbers in the IP addresses match, and that the subnet masks on every device are identical.
• If you have made configuration changes that might be causing networking issues, reset all network settings
to the factory default values.
• If you connected the Fusion Apollo device to a Garmin chartplotter using a wired Garmin BlueNet or Garmin
Marine Network connection, the network settings on the device should change automatically to GARMIN
MARINE NETWORK.
If the network settings do not change as expected, reset the network settings on the device (Resetting
Network Settings, page9).
Network Status Icons
A network-status icon is shown on some screens of the device. You can refer to this table to understand the
appearance of the icon and help diagnose issues with the Fusion PartyBus network.
The device is connected correctly to a network.
The device cannot detect the network. An Ethernet cable may not be connected or there may be other
problems with the network.
Software Update Troubleshooting
If the downloaded remote control software update does not complete successfully, perform these steps.
• Make sure the update file you downloaded is intended for the remote control model you are updating. Only
software update files intended for the specific remote control will update it.
• Make sure the update file is a newer version than what is presently installed on the remote control. Only
newer software update files can be installed on a remote control.
• Make sure the update file was extracted from the .zip file and loaded onto the root of the USB flash drive.
When properly prepared, the USB flash drive will have a directory named Garmin containing the update files.
• Make sure the USB flash drive is formatted using the FAT32 file system. The stereo will not apply an update
from a USB flash drive formatted using the NTFS file system.
• If the remote control is part of a Fusion PartyBus network group, remove it from the group before starting the

The remote control does not update as part of a Garmin network update
If you are attempting to update a remote control using a Garmin chartplotter on a network, and the remote
control software update does not complete successfully, perform these steps.
• Make sure that the remote control you want to update over the network is using software verison 6.20 or
later. If any connected remote controls are using an earlier software version, you must update it individually
using a USB flash drive or the Fusion app before it can be included in a network update.
NOTE: If you are initiating the software update from a Fusion stereo, it must be using software version 6.40
or later.
• If the network update fails the first time, try it again before further troubleshooting.
• Try disconnecting any Bluetooth devices, and try the update again.
• Make sure the remote control is connected properly to the to the Garmin chartplotter using an Ethernet cable.
• If your network contains both a Garmin BlueNet chartplotter and legacy Garmin Marine Network devices,
make sure the remote control is connected to either the Garmin BlueNet chartplotter or a Garmin BlueNet 20
switch. See garmin.com/manuals/bluenet for more information.
• Make sure that all stereos and remote controls connected to the network are set to GARMIN MARINE
NETWORK as the network type.
• Make sure that all the stereos connected to the network are set to WI-FI OFF.
• If you cannot change the network type or set WI-FI OFF, reset the network settings on the remote control or
stereo (Resetting Network Settings, page9).
