In the process of having ES128 and ES127 MFD's installed in my Regal 42 Sport Coupe. I primarily use Navionic's Charts. The two displays will be networked together. My question is whether I need to purchase 2 chart chips or can I just use one to support both displays? I don't want to move the chip from display to display. Thanks.
