C120 Classic upgrade to C120 3rd generation

Hi have a C120 classic vintage 2004 which connects to a Raymarine dome radar, autohelm auto pilot and tridata instruments all vintage 2004. I was thinking of replacing the C120 with the newer C120 3rd generation to get a brighter display as well as some new features included with the 3rd generation.

My questions

would the new MFD be compatible with my existing connections as radar and autopilot ? Simply plug all existing cables into the new MFD.

Also could I interface the new MFD with a Quantum radom as a backup to my older radom either via a wire or wifi/blutooth?

The existing MFD is mounted is surface mounted would the new MFD fit into the existing cutout?

Thanks



Thanks
