[CA] [CA11] E120 shows only AIS MMSI info not vessel names

[folkmeister]

My old boat had e7 and AIS 650 and worked great, all AIS info was displayed for all targets.

On our new-to-us boat, we have suffered a downgrade of MFDs to an E120 and E80. We just installed and integrated a Vesper XB-8000 AIS unit. Oddly, on the MFDs we only see vessel names for very large yachts and ships. For the rest of the AIS targets, we see just MMSI number, no vessel name. As we typically hail other vessels by name this is less than desirable. Both MFDs are updated to the latest / final version of their MFD software. Is there some inherent limitation of these older MFDs in ability to display some AIS info?
