RL70C Plus System Upgrade

[Elba]

I had the marina install the AIS650 and somehow they smoked either the Radome Scanner or the display. Apparently parts are no longer available, so the question becomes, what replaces the current equipment? Would like to get as close to the original equipment as possible. Here's what's on board;
4kW Radome Scanner (48nm).
Type 150/400 Auto Pilot
RayNav 300 GPS Plotter
RL70C Plus 7" Color Display
ST6001 SmartPilot Controller
ST60 Tri Data
Ray215 VHF Radio

Or, will any of this interface with the new display/radar?
