will accept a radar component then the answer is simple. If not, well, I'd get one. Getting a stand alone Radar doesn't make to much sense these days. The basic entry level chart plotter from Garmin or Ray Marine is a good place to start. IMHO. I have the Garmin 3210 which is out dated now and I'm still quite happy with it. You could probably pick one up used including the Radar for the price of a new stand alone model.
