Question 1:
I just installed new G4N units to replace my G3N units, and an Ulterra with built in MDI+
Helix 15 MSI+ G4N CHO up front.
Helix 12 MSI+ G4N at the console
MSI+ transducer at the transom.
I want to run the MDI+ and 2D for the Helix 15 off the Ulterra's built in transducer, but I don't see it as an option in the Network Source tab.

Question 2:
I'd like to take advantage of the G4N's built in NMEA capability.
I run a 2005 Johnson 140 4 stroke, same motor as a Suzuki DF 140.
I can see how to turn everything on in the menus, but I don't know how to connect to the motor.
I am digging through the manuals this evening, but any help is appreciated.
