Helix G3N-G4N transducers

[chatabass]

I have helix 10 MSI-MDI G3N unit at the console with a SI transducer on the Stern and a puck in the bilge. It was installed new in 2021 with the SI transducer that was in the box. I don't know what the model# is of either transducer(I've looked). I'm thinking to upgrade the console to a 12", will the Helix 12 G4N MSI-MDI connect to the existing transducers? Did Hummingbird improve/change transducers between G3 and G4, does anyone know?

No difference if the technology is the same.
The transducer model names are on the bar code sticker about 12" from the plug.
XM 9 HW MSI T is the Side Imaging transducer.
XP 9 HW T is the shoot-thru.
