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. In the M506-21 and M506-41 versions only

NMEA 2000® and NMEA 0183 Connectivity

With the plug-and-play functionality of NMEA 2000 in the NMEA2000 models, 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. The M506-01 only has NMEA 0183.

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.


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.

Large LCD and Intuitive User Interface

The IC-M506 is equipped with 132x96 pixels dot-matrix display which is larger than the IC-M504 (132x64 pixels). Reading GPS, AIS, DSC and radio menus are easier than ever. The bottom line of the display shows the software key functions and the functions can be toggled with the left and right buttons.
