Replacing Simrad CX34

[Lantau]

I would like to replace my Simrad CX34 chartplotter.

Does anyone know if it's possible to replace the CX34 with a current chartplotter that can still (1) operate and display a decade-old Simrad radar unit (RB714A, I believe) and ideally also (2) communicate with B&G Network system instruments (depth, wind, speed and autopilot)?

My Simrad/B&G dealer says it's impossible, but I'm hoping that he hasn't considered (or isn't aware of) creative alternatives to wholesale replacement of my systems (which would require new radar, new autopilot, new instruments with new transducer thru-hulls, including different sized holes, etc.).

Thanks in advance for any help.
