Applying Software Updates
From time to time Simrad releases software updates to it’s existing products. Updates are
created for a variety of reasons; to add or improve features, to add support for new external
devices, or to  x software bugs.
Updates can be found on the Simrad website: http://www.simrad-yachting.com/Downloads/

The NSS may be used to apply software updates to itself, and to external SimNet and CZone
devices, with  les read o a Micro SD card.
Before initiating an update to the NSS itself, be sure to back up any potentially valuable user
data.
Backing up user data
There are two  les that can be backed up that relate to user changes:
• Waypoints Routes and Tracks
• Settings (includes preferences such as unit settings, and custom new pages)
The backup procedure is similar for both.
The  le formats for waypoint backup:
• User data  le version 4: Use with current Navico MFDs (NSE, NSO, HDS). O ers most detail
• User data  le version 3 (with depth): Use with legacy Lowrance GPS chartplotters
• User data  le version 2 (no depth): Use with legacy Lowrance GPS chartplotters
• GPX (GPS Exchange): Use with some other manufacturers’ GPS products, and PC applications
• Northstar .dat (no Tracks): Use with legacy Northstar chartplotters
The Serial port option outputs the waypoints over NMEA 0183. The receiving GPS/PC will typi-
cally need to be set to allow import of waypoints.
If the NSS is defaulted, or user data is accidentally deleted, simply return to the  les page,
highlight the backup  le, and select Import. View  le details for creation date.
NSS software updates
The update  le must be loaded to the root directory of the SD card.
In the  les menu, locate the update  le on the SD card and select Upgrade. Accept the
prompt to reboot the unit, and wait a few moments as the unit restarts. After a fews seconds
the unit will display something similar to the following image:
