To save me an hour going through the Garmin blurb on Monday does anyone have the 2010c plotter settings and colour codes of the NMEA in and out for this plotter.
If it's accessories you're connecting (as in vhf, sounder etc.) grey out, violet in.
Data -ve just connects to ground. Black in the Garmin cable but any local ground will do.
Also, go into the menu system and set the interface for port 2 to nmea in/nmea out. The alternative Garmin/Garmin sentences are not usually understood by other equipment.
