Hello, I would be very grateful if you could help me with a doubt about the raymarine units i have un my boat. At present, I have a
Raymarime e120w Chartplotter,
Raymarime smarpilot s1
Raymarime ST8002, and a
Raymarime DSM30.
Raymarine seatalk

Raymerine RD418 4KW 18" radome
I would like to change my E120w for a refurbished E125, and my first question is if this multifunction display (E125) is compatible with the rest of my raymarine units? The second question is that, in case that I decide to adquire a E127 or E128 multifunction display, which units should I have to replace or which equipments would i need to install? Would my transductor would be compatible with the E127 or E128 (I don't know which model is the transductor I have, but one compatible with the DSM30? Thank you very much for your time. Best regards, thanks very much
