Installing new Icom ic-m400BB replacing Northstar NS100 this weekend on my 330DA. Anyone have any tips/tricks or is it straight forward? Thanks all!

I replaced a crappy Raymarine radio with the 400 BB very straight forward, run power ,antenna and if you’d like NMEA 0183 for DSC from your plotter and your done. Every radio on our boat is ICOM that’s 5 in total. I’d never buy any other brand.
Thanks. I have a Raymarine RL80c and a Sea Ray Navigator. I thought they might be too old to communicate with the new radio.View attachment 58557 SRMARK,
The radio she “talker” connections and “listener” connections
They have +/- so you should have 4 wires being connected
+ for listening + for talking etc.
You need to know the connections of your plotter. Just google it.

Page 14 has the diagram
Hate to revive an old thread, but did you wind up hooking both the "listener" and the "talker"? I'm going to replace my old Northstar with the Icom m400bb soon, and I hate to reinvent the wheel.Ok, I will try hooking up both. Thanks
Hynespa - Thanks for the diagram! It makes things a lot easier to understand - the instructions that came with this thing are a little on the "thin" side.@Windjammer - the attached diagram shows how I hooked up my NMEA talkers and listeners from the iCOM to my MFD. The listeners get the GPS position from the MFD and the talkers communicate the coordinates of other boats so the MFD can display it.
Well, changed out radios yesterday and I sure do like the Icom. As with life, things don't always go as planned - in this case you really don't know what you've got until you crack open the dash panel and try to make sense of what I would call a "rats nest." I found the correct NEMA0183 wires from the C80 (talker) to the Icom (listener), and temporarily hooked these up and sure enough, position and time were sporadically displayed on the Icom. But could not find the listener wires going back to the C80 but eventually found the cable and these had been cut off. Why, I don't know as the old NS100 had the DSC capabilities, but DSC on our inland lake is probably an overkill. Went up today to clean up my mess and now the Icom won't display the location/time info. I'm guessing that operating under a metal dock may have something to do with this or one of my connections pulled loose. Will test tomorrow as I've got to run the boat over to a mechanic to get the impellers changed. We'll see what happens.Hynespa - Thanks for the diagram!

Is the unit displaying ????????? or nothing at all?
I’m under a metal roof and loose GPS position. In that case the ICOM beeps at me about every minute or two. If I kill power to my network, I get ????????? Where data should be.
Igbo help you track down what’s going on.
