NOT a substitute for a chartplotter
the cartography is excellent but there are no nav. functions. no data boxes, no speed, no heading or course. NO HEADING LINE. no GO TO function. just a boat icon on a chart. not really useful as a proper plotter. Use Navionics or INavx if you want an iPad chart plotter. this is simply a planning tool only. i think garmin dumbed this app down on purpose it could have been excellent with a navigation module. I got my money back. ( thanks Very much apple for the excellent service )
