should do more. I have a Garmin 3210 chart plotter and while it charts the other boats, it needs to be connected to my lap top to be able to view the various control screens. I don't know if that's normal because I haven't been able to find anyone at West Marine that really understands them. At least not one that's connected to a 3210. I would like feedback on this question as well. I do know that it's manufactured by a relatively large maker of AIS units and West just puts it name on it. I had the info on the company but misplaced it. I searched Google for AIS and found it without much trouble.
