Width & Height clearances
• Navionics® Autorouting and Dock-to-dock does not use the user defined Minimum safe width or
Minimum safe height settings when generating routes. Objects with width / height constraints
are marked with hazard waypoint symbols, it is critical that these legs are checked to ensure that
there is sufficient clearance to avoid the hazard.
• C-MAP® Easy Routing uses the user defined Minimum safe width and Minimum safe height
settings to determine if sufficient clearance is available. The user must apply their own safety
margin as appropriate to current conditions. The Height datum must be checked, as it could be
Mean High Water Springs (MHWS) or Highest Astronomical Tide (HAT). In both cases the tide can
be higher than the datum due to atmospheric effects such as high air pressure, wind direction, etc.
Reviewing an automatically generated route
Before following any route you must ensure that it is safe to do so.
Upon Route completion:
1. Range in on each route leg and waypoint that make up the Route.
2. Check either side of the route leg and around the waypoint for any possible obstructions.
Obstructions can be charted objects or restricted areas. Routes generated automatically should
use the caution waypoint symbol in areas where there are possible obstructions.
3. Where obstructions exist move the necessary waypoints so that the waypoint and route leg is
no longer obstructed.
Importing a route
You can import routes created in standard gpx format.
1. Save your route to a memory card.
2. Insert the memory card into your MFD.
3. Select Import from card from the Import/export page: Homescreen > My data > Import/export
> Import from card.
4. Locate and select the gpx file that contains your Route.
The Route will be imported to your MFD.
Route management
Routes are managed using the Route list.
The Route list can be accessed from the Homescreen and from the Chart app: Homescreen > My
data > Routes, or Chart app > Menu > Waypoints, routes, tracks > Routes.
If the Route list is accessed from the Chart app menu, then the selected route is displayed in a
Chart pane on the right of the screen.
Route list
From the route list you can Delete routes or create a New route using existing waypoints.
To view a route plan, select a route and choose View route plan.
Route plan
The route plan displays a list of all waypoints in the route and when accessed from the Chart app
also includes a Chart pane showing the route's location.
