Zeus³ Software Update

Following on from the release of 18.3 software for the Zeus³ MFD series, we have identified a possible reboot issue which could happen at random.

Working with our internal SQA Teams, we have identified and solved this issue. A user update to the current software version (18.3-61.1.157) will resolve any in field problems.

Any Zeus³ MFD should be updated to the latest version, which is available to download below.

B&G are pleased to announce a software patch for the Zeus and Vulcan range of multifunction displays following the release of 18.3 in January. This new release incorporates various improvements and fixes which were identified by our internal SQA teams and customer feedback since the release.

Improvements and Fixes

· WiFi-1 Module firmware

o The B&G 18.3 software contained a firmware update for the WiFi-1 module which under certain conditions could cause the module to stop responding. This has been resolved and the latest patch checks the external WiFi-1 module before carrying out any updates to see if update is required.

· “No Radar” message

o In limited situations a connected Radar would report “No Radar” upon power up leaving the radar inoperable. This has been resolved.

Note: Any existing WIFI-1 module which is unresponsive, please contact your local Navico Service team.

The latest software version is available to download from this page or direct from an MFD connected to the internet.

B&G are pleased to announce the release of the latest update for the Zeus3 Series. This new release incorporates several new features and various improvements and fixes.

New features:

C-Map Embark Sync


It is now possible for MFDs to synchronise Waypoints, Routes and Tracks with the C-Map Embark passage planner app available on iOS and Android. This allows points of interest along with pre-prepared routes to be transferred to your MFD from the comfort of home.

Download the app for iOS

Download the app for Android

Dual Mode WiFi

It is now possible for compatible MFDs with built-in WiFi to simultaneously connect to the Internet and your mobile device. This allows Navico’s Link app to be used while the MFD is connected to the Internet.

Menu and Tool Icon Changes

The Chart Menu has changed to a simpler layout to make it easier to find the desired setting. Along with the change to the Chart Menu, the ForwardScan menu has also been changed.

In addition to the Menu Changes, the “Files” tool user system has been renamed to “Storage” allowing direct access to Waypoints, Sonar Uploads and Transfers.


* Added support for the new NMEA2000® MOB PGN

- No change to how MOB feature operates today, but will now trigger with a range of external devices using NMEA2000®

* New progress bar added to show progress when calculating a route with Navionics Dock-2-Dock Auto-Routing feature.


* Fuel Remaining source is correctly stored during power cycles

* Fix for some missing tide stations with Navionics charts

* Instrument panel not working when system language is set to Greek

B&G are pleased to announce the release of the latest update for the Zeus3 Series

Key features:

New Software Naming Convention

Previously software RTM (release to market) version numbers were device specific e.g. a Vulcan 7 could be have a version number of 4.0 while a Zeus² could have a version number of 7.0 even though the software is from the same feature stream This causes confusion as to what products have what features.
• From now on, all the software from the same feature stream will have the same version number irrespective of model
• The new version number is made of the Year and the sequential release number in that year. In this case for this version,18.2 means that it is the second release for 2018.
• Update file names will have the new Version number

Display Text Message



Compatible MFDs that have built in Bluetooth can now pair with a mobile phone and allow text messages to be displayed on the MFD.
Depending on the type of phone, other functionality may be available:

Fixes and Improvements


  • Added support for Fusion Radios via Ethernet communications
  • An option is now available for a user to select when they would like to receive the next notification for software updates

Bugs Fixed

  • Phantom Loran position can be viewed in the instrument panel

Mark Rounding Indicators

To enable quick and easy identification of mark rounding directions when racing the latest update allows users to set a specific course as a race, which then automatically applies mark rounding directions based on the relative angle between legs of the course.  These angles can be edited by the user to match those provided by the race committee, if different.


Colour Tracks

The system can now dynamically change the colour of a track based on a source of data.

Track colour can be based on the following data sources (if available):-

  • SOG (Boat Speed over ground)
  • STW (Boat speed though water)
  • Wind Speed (True wind speed)
  • Wind Speed Apparent (Apparent Wind Speed)
  • VMG (Velocity Made Good)

Coloured Tracks

The colour scale will use red to show the lowest value and green for the highest with the mean value shown in yellow.

Enable Colour Tracks using the option in the side menu under Chart Options. Once turned on the unit provides the ability to set the data parameters.

Heat Map

Heat map is a new Chart Overlay that shows a history of the sea surface temperature where the boat has been. The Sea temperature history is shown as a coloured line where the boat has been. A sea temperature sensor is required and set as a source of Sea Temp in the Network settings. The colours relate to a key that is visible when the overlay is active. The keys values will automatically adjust based on the current temperature reading. The pallet of the Heat Map and key can be adjusted.
