Re: Standard Horizon Matrix AIS+ GX2150
Sorry, can't talk you out of it, I have one and it's great.
Please note that you'll need to connect the VHF to the chartplotter anyway, because the VHF needs the GPS position for AIS to work at all (and for DSC, so two reasons to connect it) So at that point, you might as well connect it back the other way to see AIS targets on the plotter.
What kind of plotter do you have?
