To resolve this issue, delete the Fusion-Link app from your device and then reinstall it.
Sorry, only Apple devices have the capability to navigate media libraries over Bluetooth.
Over-the-air software updates are only available for the Apollo Series. All other Fusion stereos require a USB stick loaded with an update folder connected to the stereo to perform an update. "Error" will display if there is no USB device connected, the USB device is not formatted correctly, or if the file is not in a folder named "update".
