Installation Instructions
Periodically FUSION may issue software upgrades for your product, these upgrades can be downloaded directly from the FUSION website.

Note: Upgrading your unit will require the use of a USB flash drive with at least 15Mb of free space.

Download the update
Download the update zip file to your desktop or your designated download folder.

Unzipping the update file
The update file is provided in a WinZip (.zip) format. An unzip utility such as WinZip is required to unzip the file. Unzip the file using the WinZip command ‘Unzip/Extract Here’ or equivalent in your unzip utility. A folder called update is created, containing the update files. Either extract directly to your USB flash drive or move the update folder to your USB flash drive manually .Note: You should only have a folder named "update" in the root directory of your USB device, if you can see multiple files the update will not execute.

Installing the upgrade
After the file has been unzipped and copied, insert the USB flash drive into the USB connector of your marine stereo.
Finally press the ‘Menu’ key and select ‘Settings’ then select ‘Update’. Select ‘Head Unit’. The words ‘Updating and then success...’ will appear on the screen and after a short duration the unit will restart.

Warning: When upgrading your unit, all AM and FM station presents are erased. Tuner regions are reset to USA. All zone settings, tone, subwoofer filter settings, source settings and device name are returned to default values.
If you have one or more MS-NRX Wired Remotes controls or a MS-DAB100A DAB Module connected to your head unit they must also be updated. The update is performed from the Marine Stereo. Ensure all of the remotes are powered on and connected to the stereo. On the Marine Stereo press the ‘Menu’ key and select ‘Settings’ then select ‘Update’. Select ‘MS-NRX Wired Remote’ or DAB Module. The stereo will display UPDATE on the screen and show progress.
The MS-NRX Wired Remote remote will power down and restart at the completion of the update process.

Note: During the update process do not power down the remotes.
We recommend once the update has completed on the head unit and remote that you confirm the software version aligns with the version number of the update. Go to Settings > About to view the version and Build number. Repeat on the MS-NRX Wired Remote
