[CA] Equipment Upgrades

I have the following on my boat and would like to replace the chart plotter and possibly the radar.
Current Equipt.
RL70C Chartplotter
Pathfinder 18" Radome
Smartpilot ST 8001 Auto Pilot
Raystar GPS Receiver

I am looking at the following:
E120W Chart Plotter - Not sure of the SN as it's still on the boat but here are some numbers from the box. E6223, N16821, AE622231096095, 091975004797

Radome 24" Product code M92652-S & S/N 0450486

Questions:
Will the E120W work with my current Radar, Auto pilot & GPS receiver
If my current radar would not work, would the one above work.

I appreciate your help in answering my questions.
