FAQs
Why does my stereo become unresponsive when I try to play music from the attached USB flash drive?
The 70 Series stereos supports a maximum of 250 MP3 files per folder and must be in the root directory of the USB device. (You cannot place a folder inside another folder and the max number of 250 files/folders applies to the root structure)
What is the current consumption of my FUSION stereo?
Current consumption of Fusion marine stereos:
Fusion stereos have a standard voltage rating of 10.8V to 16V DC unless otherwise stated.
All figures are for individual head units only, not a system. Numbers can be added together to calculate the system current consumption.
Amplifiers will contribute significantly higher current consumptions.
All marine stereos with 4 amplified speaker outputs have been tested with 4 speakers attached and no USB devices connected.
All measurements are average, so measurements on other production stereos may vary. Values are subject to change without notification.

Introducing the MS-RA70NSX, Fusion’s sleekest value-packed marine stereo now with SiriusXM capability, designed to deliver a quality on-water entertainment experience by incorporating some of the latest marine technologies. The MS-RA70NSX is engineered to seamlessly replace any standard DIN sized non-marinized stereo without the need to reconfigure dash space. Clever styling gives the installer the option of either mounting the stereo with a conventional flush finish or integrating it flat into a glass helm, ensuring a high-end finish to the installation.
Features:
SiriusXM-Ready™ with advanced features (USA only) - SiriusXM satellite radio is available, along with a selection of advanced features:
- Instant Replay, where you can replay songs from up to 1 hour past playing, making sure you never have to miss another beat of your favorite tunes.
- TuneStart, where you will always hear the song playing on each of your favorite stations from the start, no matter how far along it is when you change the channel.
- TuneMix, where you can create your own channel from a mix of your favorites to create your very own custom channel. TuneMix also gives you the ability to skip songs back to the last hour you have been listening across all channels in your mix.
- SportsFlash, where you’ll receive key plays and updates from your favorite teams during live games, ensuring you never have to miss the best moments.
- Artist, Song and Game Alerts, where you can choose to receive alerts whenever your favorite artists, songs or sports teams start playing.

In addition to MFD control, the MS-RA70NSX will connect to any Fusion NRX series remote control attached to the same powered NMEA 2000 network for localized control of the audio zones. (Note: the NRX remote must be incorporated onto a powered network. If you are planning on using the MS-RA70NSX and a NRX series remote on a standalone network, additional cabling is required to power the network).
