iNavX allows you to BUY charts from others. These are charts specifically formatted for that application. It does not allow you use electronic charts you already own for other applications, like Coastal Explorer. In other words, you can buy, for example, CMap charts for iNavX, but you can't just use your CMap charts that you purchased for your chartplotter.

So you are in effect buying charts again.

That is the way I understand it - is this correct?
