Troubleshooting

The stereo does not respond to key presses

  • Hold Power button until the stereo turns off, and turn it on again to reset the stereo.
  • Disconnect power to the stereo for two minutes to reset the stereo.

The stereo does not receive DAB stations

NOTE: The Fusion Apollo™ RA800 includes a built-in DAB module and receives DAB signals through a standard AM/FM antenna.

My Bluetooth audio is interrupted by short breaks

  • Ensure the media player is not covered or obstructed.

    Bluetooth® technology performs best with line-of-sight operation.

  • Bring the media player within 10 m (33 ft.) of the stereo.
  • Turn off the DISCOVERABLE setting after pairing a Bluetooth device to the stereo.
  • Wi‑Fi® signals may interfere with Bluetooth device connections. You should turn off the Wi‑Fi setting on your stereo if you are not using it.

The stereo does not display all song information from my Bluetooth source

The availability of song information such as song title, artist name, track duration, and album cover artwork depends on the capability of the media player and music application.

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 wireless Fusion Apollo devices are connected to a wireless router or wireless access point on the network.
    NOTE: Wired connections are more reliable than wireless connections. If possible, you should connect devices to the network using an Ethernet cable.
  • 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).

Network Status Icons

A network-status icon is shown on some screens of the stereo. You can refer to this table to understand the appearance of the icon and help diagnose issues with the Fusion PartyBus™ network.

Ethernet connected symbol

The stereo is configured for a wired network connection and connected to a wired network using an Ethernet cable.

Ethernet disconnected symbol

The stereo is configured for a wired network connection, but cannot detect the wired network. An Ethernet cable may not be connected or there may be other problems with the network.

Wi-Fi accessory configuration symbol

The stereo is in Wi‑Fi accessory configuration (WAC) mode, which allows for an easy connection to Apple® devices.

Wi-Fi access point symbol

The stereo is configured as a wireless access point.

Wi-Fi connection symbol

The stereo is configured as a wireless client and connected to a wireless access point. The number of bars indicates the signal strength.

Wi-Fi disconnected symbol

The stereo is configured as a wireless client, but is not connected to a wireless access point. There may be a problem with the connection settings or with the wireless access point.

Software Update Troubleshooting

If a stereo software update you downloaded from the Garmin website does not complete successfully, perform these steps.

  • Make sure the update file you downloaded is intended for the stereo model you are updating. Only software update files intended for the specific stereo will update the stereo.
  • Make sure the update file is a newer version than what is presently installed on the stereo. Only newer software update files can be installed on a stereo.
  • 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 file.
  • 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 stereo is part of a Fusion PartyBus network group, remove it from the group before starting the update.

The stereo keeps locking up when connected to an Apple device

  • Press and hold the power button to reset the stereo.
  • Reset the Apple device. Go to www.apple.com for more information.
  • Make sure you have the latest version of iTunes® and the latest operating software on your Apple device.

The stereo is not finding my connected Apple device

  • Make sure your Apple device supports Interface Accessory Protocol 2 (iAP2). This stereo is not compatible with iAP1 devices.
  • Make sure you have the latest version of iTunes and the latest operating software on your Apple device.
  • Make sure you have the latest version of the Fusion® Audio application on your Apple device.
  • Try rotating and re-inserting the USB-C cable into the stereo.
  • Try using a different cable, preferably an Apple OEM cable.
  • If you are using a USB-A to USB-C adapter, try using a different adapter.
  • Reset the Apple device.

    Go to apple.com for more information.

  • Contact your Fusion dealer or go to support.garmin.com.

My Apple AirPlay audio is interrupted by short breaks

  • Make sure the Apple device is not covered or obstructed.
  • Make sure the Apple device has a good connection to the same Wi‑Fi network as the stereo.
  • Make sure the Apple device is not connected to the stereo using Bluetooth technology and Wi‑Fi.

    Using both a Bluetooth and a Wi‑Fi connection may cause playback interruptions.
