Icom IC-M506 Fixed Mount VHF and AIS Receiver Combo with NMEA 2000 Connectivity  (CITC Licensed)

Integrated AIS Receiver*

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

NMEA 2000™ Connectivity*

With the plug-and-play functionality of NMEA 2000, the IC-M506 can easily connect to a NMEA 2000 network. The ICM506 can receive and transmit GPS (position, course (COG) and speed (SOG)), AIS report and DSC call information data and transmit radio frequency and PGN list data on the network. Using this function, the IC-M506 can convert NMEA 0183 GPS data to NMEA 2000 data for other equipment.

Last Call Voice Recording

The last call voice recording function automatically saves the last two minutes of the last incoming call. You can replay the received call, and not miss any incoming call.

Active Noise Canceling

Using digital signal processing technology, the built-in bidirectional active noise canceling provides superb performance. It reduces background noise to up to 90% in the received signal and 30% fixed in the transmitting signal. The function OFF setting is also possible.

Intuitive Menu-Driven User Interface

The intuitive software key functions provide easy and fast operation to control the multiple functions of the IC-M506. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons.

25 W Two-Way Hailer

When connected to the optional horn speaker, SP-37, you can talk with crews on the deck or shore from the radio’s microphone and can hear any reply via the horn speaker. The RX hailer function allows you to monitor the received audio from the horn speaker. The built-in 25 W amplifier increases your talk power, making it loud and clear.

Built-in Horn (Automatic & Manual)

When connected to the optional horn speaker, SP-37, four horn patterns are selectable for the automatic horn function.


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. Up to 100 DSC address IDs can be programmed.

Rear Microphone Version*

With this version, the microphone connector is drawn from the rear panel and a 6.1m (20ft) microphone extension cable is supplied to allow you clean and neat panel installation.
