The new release of the iNavX v4.7.4 navigation app streamlines the operation of its charting software designed for iOS mobile devices. In addition, the X-Traverse chart lists updates in real time. The app displays the current position using a mobile device’s built-in GPS, plus creates waypoints and plots courses. INavX also integrates with AIS and networked instruments, and external GPS sources such as depth and speed. GRIB weather forecasts can also be downloaded and displayed on the app.
