[Erie210elite]

I have 3 Garmin GPS maps a NEMA as well as live scope and live scope module box. I want to add a 4th graph do I just need the Garmin Network cable and what do I connect it to or do I network it through NEMA obviously I will need a power cord anything else I may be missing? I appreciate the assistance

First, the 4th unit will need to be another GPSmap unit. You already said the other units are connected via N2K and going to assume they are also connected via network cable (ethernet), then all you would need is to another ethernet cable and N2K cable to connect to the others. Now if you dont have any additional network plug on the other unit to connect to you will need to add the network port (GMS10).

ONE MORE QUESTION MY NEMA BACKBONE IS AT THE FRONT OF THE BOAT. MY GRAPH ON THE CONSOLE IS CONNECTED TO IT. I AM ADDING THE OTHER GRAPH AT THE CONSOLE IS THERE A WAY TO CONNECT IT AT THE CONSOLE OR AM I GOING TO HAVE TO GET A LONG CABLE AND CONNECT AT THE BACKBONE? OH AND YES THE OTHER GRAPH IS A GPS MAPS

You would need to drop another tee and drop cable on the network at your console. Not sure what your network looks like but should generally be like below.
