Icom M506 VHF Fixed Mount w/Rear Mic, AIS & NMEA 0183/2000 features:

Integrated AIS Receiver
With an integrated AIS receiver, the IC-M506 can show AIS vessel traffic
information on the display. The AIS target call function allows you to
easily set up an individual DSC call. The Plotter, Target list and Danger
list can be toggled on the display.

NMEA 2000 and NMEA 0183 Connectivity
With the plug-and-play functionality of NMEA 2000, the IC-M506 can easily connect to a NMEA 2000 network and interconnect with other equipment. Also the NMEA 0183 input/output can be used for external GPS/NAV interface.

Last Call Voice Recording
The last call voice recording function automatically saves the last two minutes of the last incoming call. You can also start recording manually.

Active Noise Cancelling
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call.

25W Two-Way Hailer
When connected to an external hailer horn, you can talk to people on the deck or shore from the radio's microphone and can hear people's reply via the hailer horn. Foghorn and RX speaker functions are also available.

Optional COMMANDMIC HM-195B/SW
The optional COMMANDMIC, HM-195B/SW provides 2nd station capability for using the IC-M506 from a separate cabin or tower. Most functions including DSC and AIS functions can be controlled from the COMMANDMIC and can be used as an intercom between the IC-M506 and the COMMANDMIC.
