Navico is the overall brand behind the B&G, Simrad and Lowrance MFDs.
Navico compatible hardware:
Note that this feature also works on the NSS EVO2. But only limited. And its not officially supported and also there will be no new software releases made by either Victron nor Navico to fix any issues that may arise. In other words, it is not a supported configuration by Navico but the consumer can feel free to use it (if they contact Navico or Victron service, our team will tell them it is not a supported configuration). More testing and user feedback will have to show what does and what does not work on the EVO2.
The Navico device needs to be connected to the GX device using Ethernet. Its not possible to connect over WiFi. For the ethernet connection, a Navico adapter is required as the Navico MFDs feature a round water proof connector on the back. The adapters can be purchased from Navico:
On the Victron GX Device, go to Settings → Services, and there enable MQTT.
Next, go to Settings → System Setup → Scroll to the bottom → Battery measurements. And there set up what batteries you want to see on the MFD; and by what name.
No other settings, such as IP addresses or similar are required. The GX device and the Navico devices connect to each other using a technology called linklocal addressing.
It is possible to connect the a router to the same LAN; and that way connect the GX Device to the internet.
TBD add screenshots and so forth.
