Your right on the redundancy thought. "Remember it is not a plotter with includes chart data. It provides GPS position course and speed input to the AIS system in the radio"
Its own GPS gives me a display on the face of the radio of my COG, SOG, Heading LON, LAT, and speed all on the radio. If I have Failure at the helm with the Garmin and my hand held is not close I will have the radio for pert information. The other thing I like, If I need help I'm at the radio inside the cabin on the radio I can not see the GPS at the helm at the same time. If my wife has lost lost me to Neptune or old age she now can stand at the radio and have all the information in front of her. Its clame is " *Integrated 66 Channel WAAS GPS antenna* The GX2200 MATRIX AIS/GPS, features a 66 channel WAAS GPS antenna integrated into the front panel of the radio, now there is no need to hassle with wiring the radio to a GPS for DSC (Digital Selective Calling) or AIS (Automated Identification System). Out of the box and ready to go, acquiring AIS and AIS SART targets, DSC calling, position sharing, way point navigation, and navigation to DSC distress calls can all be performed with just a few simple steps." But the problem is if you want to see other transmitting vessels at the helm on the Garmin Echo 50s, it would need to be wired to the GPS. I'm not sure if I will have to turn off the radio's GPS to do this or if the Garmin is smart enough to take in the other GPS location from a different source? I need to do more reading. Ether way, I ordered the radio yesterday and should be here on Wednesday. I think it was a good choice. My Garmin will except 0183 and 2000 so that is not a problem today but may be that in the new radio by design. They will need a new model. marketing plan. I hope to report a good review after i hook mine up .
