I navigate using true heading and not magnetic heading; how do I use the SSC200 compass and N2KView software to view my heading in true?

The SSC200 compass outputs heading information in magnetic form and before N2KView can display true heading, the variation must be known. One source of variation is the Maretron GPS antenna/receiver (GPS200). If an SSC200 and GPS200 are connected together on the network, the true heading can be computed and displayed on N2KView. To view true heading on N2KView, click on the "Units Setup" tab, and select "Magnetic from the "Heading/Course/Bearing" setting. If you try and select true heading and there is no variation source, N2KView will not show a heading.
