New Icom marine family user interface
The new menu system provides easy and intuitive operation. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons. The directional keypad allows you to perform various operations and settings.
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. You will hear better, be heard better.

10W Loud Audio, Public Address and Foghorn
The IC-M424 has a built-in 10W amplifier that increases the audio output from additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the additional external speaker.
Built-in Class D DSC
The built-in DSC watch function monitors Ch. 70 (DSC channel) activity, even while you are receiving another channel. DSC functions include: distress, individual, group, all ships, urgency, safety, position request/report, polling request and DSC test calls.

New Optional COMMANDMIC IVTM HM-195B/SW
The new optional COMMANDMIC IV™ makes it convenient for using the IC-M424 from a separate cabin or tower. All functions of the IC-M424 can be controlled from the COMMANDMIC IV™.
Common GPS/NAV Interface
When connected to an external GPS receiver, current position and time are shown on the IC-M424's display. When receiving position information from another vessel, the IC-M424 can transfer it to a navigational device via NMEA 0183 connectivity.
MarineCommanderTM Compatible
When connected to the MarineCommander™, the received DSC message pops up on the multi-function display.
