I am going to try this again. I appreciate the assistance but I really need to hear from Garmin users who have made this work. Garmin 8616 display connected to Cerbo via Ethernet. Looking to get Victron app loaded onto Garmin display.

I have tried

  1. Victron Ethernet cable (verified good) directly to MFD..no luck shows Ethernet connection on Cerbo but nothing else
  2. Victron Ethernet to Garmin POE to Garmin cable to MFD .. same result as above
  3. Victron Ethernet to Garmin POE to another Victron Ethernet cable to MFD .. same result as above

Using new GUI interface

MQQT is on

I would love to hear from someone who has actually made this work Thanks

I’m having trouble getting my Cerbo GX2 to communicate with my Garmin GPSMap 8616xsv

Garmin GPSMAP 8616xsv, software 43.05
Cerbo GX2, Venus OS 3.73
Direct Ethernet connection
Garmin discovers Victron._garmin-mrn-html._tcp.local
Garmin fetches /garmin/config.json
Garmin logs “Unable to parser JSON data”
Browser successfully retrieves:
/garmin/config.json
/garmin/icon.png
/app/
App runs correctly in browser
Security level change on the Cerbo to “weak” does not help

Has anybody made this work? It’s supposed to be easy.

Further to the above, here is a screenshot of the diagnostic logs of OneHelm on the Garmin 8616xsv. Stan

Hi @stanhoney,

You need to set the security profile to “Unsecured”, otherwise the MFD will be prompted with a password page and is unable to download the json file.

Hi Martin,

Thanks. That worked.

A related question. Now that the Victron Cerbo GX2 and Garmin Charplotter 8616xsv are communicating, the Garmin can display a page that exactly duplicates the pages visible on the Cerbo. Can the Garmin actually read any of the data so that the Garmin could display selected data items in a number grid or on the corners of the chart display?
