Here is a photo of my Northstar chartplotter's power/data cable. There are two black wires. I presume...
1. I can run the flat black wire that is bare inside the cable (and continuous with the shield) to DC negative.
2. I can run the shiny black wire that is probably also ground and presumably continuous with the flat black wire/shield to the Brown wire on the Uniden VHF (in their manual: "GPS ground") for NMEA. The NMEA output wire from the GPS is white and connects to the green"GPS data in" wire, it seems to me.
The manual for my model (550i) does not explain those two black wires, but the Navman manuals online look similar (Northstar was Navman), so presumably my interpretation is correct.
Have I got it right?
