I read elsewhere that the Connext doesn't need to be connected to the stereo and they ran their own controls and ignored the Connext screen. Try disconnecting the Jensen cable going to the Connext and see if stops throwing alarms?
You certainly can do that, but I think it will just constantly alarm about stereo comm errors. Or they left the factory head unit in there but just didn't use it.

I had the cable disconnected right at the head unit and it was still throwing comm errors

I'm pretty sure they just disconnected it from the Connext and no alarms.

Which "head unit"? The black box is the actual radio, the "head unit" in the dash is just a remote right?

I don't have anything in the dash. It's just the "head unit" which is under the helm - the big black box and the remote at the stern swim platform.
