Im currently running a HDS 10 gen1 with lss1 and radar with a fuel line sensor as well. 

Dilema is i wish to update to a newer touch screen to speed up the user interface. 

Option 1 is get a 7 or 9 inch gen 3 and network it. Im not exactly sure how this will work.

IE if i get a 7 with 1 port will it run everything i currently have and the gen 1 will slave to it? or do i need a 9 with more ports? 

If the gen 1 became basically a extra screen then it would be great as it works fine for everything. 

Option 2 remove the gen 1 and replace it with a gen 3 12 inch. 

Problem- selling the gen 1 to assist financing the gen 3 and then will the 12 inch simply integrate with everything inplace?

I see option 1 will have the benifit of split screens giving more available information in a easy to read format, 

But option 2 will probably be the simpler if not more costly option. With the downside that I will have only 1 screen

So has anyone integrated a network with a gen 3 and 1? 

How did it work and are you happy with it? 

Thanks
