Does anyone have one of these digital yacht AIS usb devices? Its pretty cool and it just plugs into a usb port, the one thing I'm not sure of is where it gets its gps info from? If I use it with seaclear, will it use the gps data that is already inputed to the laptop through another com port?

Thanks for any input
