Comments about ICOM M506 Class D Marine Fixed-Mount VHF Radio, NMEA 2000 Version:

This version does have AIS. The version without AIS is the 504 model.

I was opposed to AIS as I prefer the ICOM add on that provices AIS on a Chart Display. However it is handy to have the vessel infor handy for hailing purposes. I'd mount this below and use the extra microphone on deck.
