E90W Replacement

[dwlanger]

I currently have an E90W MFD which is directly connected to an HD color radome via SeaTalk, and connected to a KVH heading sensor, a TR-1 Gold autopilot, and a Lowrance Link-8 radio (for AIS) via NMEA 0183. It is also using a RayStar 130 GPS antenna. I have a separate Furuno fish finder. I'd like to upgrade this year and replace the MFD and fish finder with an all-in-one display.

I'm looking for recommendations as to a combination of large screen MFD, transponder, and adapters that would allow me to retain my current functionality without a major investment in other additional equipment.

Most of my fishing is done in Puget Sound and the Strait of Juan de Fuca, in waters ranging from 35' to 400'. Thanks in advance for any suggestions!
