A quick look at the manual for the EchoMap Plus 72sv shows that the Garmin does 
NOT recognize any AIS sentences over NMEA0183 at all.  So it looks like you 
have NMEA2000 in your future to get things connected.  I’d suggest an Actisense 
NGW-1-STNG converter to get all of your data back and forth between the VHF and 
the plotter.  It will convert the 38,400 baud high-speed NMEA0183 from the 
radio into NMEA2000 (SeaTalkNG), and should allow GPS data to get to the VHF 
the same way.
