AutoRouting technology is an automatic route planning function which will be included as a standard feature for both the ONIX and ION MFDs. It is implemented for use with  CMAP 4D charts and Navionics Platinum+ charts only. When used to plan a route, AutoRouting will automatically calculate and develop the shortest possible safe passage with warnings of potential hazards based on the vessel dimensions of draft, beam and vertical height that are entered into the My Vessel settings option.
