Icom will be running into a lot of “truth in advertising” questions regarding this erroneous feature listing, as NMEA 2000 connectivity with AIS is a prime reason to buy this unit over many other less expensive radios. It seems odd that the transmission of data through NMEA 2000 would still be listed in ICOM literature given this radio is now 3-4 years old.
If that’s the case, I’m less likely to pay the extra dough for this radio if it doesn’t perform as advertised. With a modern system exclusively relying on NMEA 2000 connectivity, why would you resort to running NMEA 0183?

So my partner contacted ICOM UK, who said that despite what is printed in the manual, the Icom M506 does not support obtaining a GPS position over NMEA 2000. The menu option to select an NMEA 2000 GPS source does nothing. Apparently they had compatibility issues with different manufacturers' MFDs when designing the radio, so at the last minute they pulled support for obtaining position information via NMEA 2000. They have asked ICOM Japan for a firmware update to fix this, but none has been forthcoming. So caveat emptor. I would still recommend this radio, on the proviso that you are able to provide position info via NMEA 0183. Without it you will still get AIS on your plotter (but not the radio), but the radio will not be able to make GPS tagged DSC calls, which is obviously concerning. It's advertised as a fully native NMEA 2000 device, but at this time it is not.

I have given Garmin a schematic of everything on it and they have not suggested changes. I failed to say in my original question that I have a GMI 20 display right next (T's attached to each other) to the GNX 20 display and the GMI 20 works flawlessly. I have switched the two drop cables between the T's. Garmin cannot explain why the GNX 20 fails and the GMI 20 continues flawlessly. Thanks for everyone's suggestions so far.

Pin-out of the cable is available online. N2K circuits have limits to the number of devices and the power consumption of all devices, length of cable, etc. Double check to make sure you’re inline. N2k also has issues if multiple power supplies exist – just in case that accidently happened. Others can probably provide more thoughts. _______________________________________________ This list is supported by the generous donations of our members.
