Turning a laptop into a chartplotter?
Where can I buy hardware that will turn my laptop into a chart plotter? I am aware there are numerous chart plotting programs, I am interested in the GPS receiver (must be wireless) and a card that will plug into the laptop…or is a built in wireless card enough?
There are a variety of bluetooth-capable GPS devices on the market. Here’s a link to get you started:

Our Acer Aspire 3613WLCi came bluetooth-ready and we use “Capn Voyager”, no problems experienced at all!
Good Luck!
