I have a new icom ic-m411 radio, and it has a import/export wire to the rear for the nmea data
Now the old radio died, hence the change,many that always worked fine, and the navman gps sent it the data for the radio to know where it was etc
Also fitted to the rib is a Lowrance hds8
I have tried connecting the icom to the navman, but it would not pick up the data, so then I tried the Lowrance, and also no luck. The boat also has a navbus, and from what I can see, I should connect it to the white wire??
Am I doing something wrong? There is a nmea+ and Nmea- so I just don't get what I am missing! I don't mind which system I connect it to, as long as it works!
Is there a setting I have to enable on something?
About to call a marine engineer, but hope maybe someone on here can give a clue
