Now, you can't navigate on this massive portfolio of charts and maps, but you sure could do a lot of planning on it. Then you can transfer routes to most any plotter via cable, card, or Internet. Note that I said any, because NavPlanner2 supports not only all the formats used by Navionics-based plotters but also GPX, KML, and others. And it can be used with Fugawi's X-Traverse to transfer data online with iNavX or iMap on an iPhone or iPad, Facebook, and more. And all the transfers are two way, so you could conceivably use NavPlanner2 to collect and enjoy tracks you made on all sorts of devices.
