Maybe. But it could be due to the MFD not knowing when it is. I'd imagine
AIS transmissions would contain time/date info, which wouldn't mesh with the 2099 date the MFD thinks it's in.
Otherwise it's quite a coincidence.
Can anyone with late model
Navico gear comment? Does their AIS still
work on an affected MFD?
I did hear people discussing their AIS having stopped working on the
VHF, but never thought to call and ask if it was
Navico equipment.
