The new changes to the auto-route function caused problems to me. It is no longer able to calculate some simple routes if they are long (producing a straight grey line instead) and adds turns/indirect courses even when a direct line is shorter (and free of hazards). I asked them to please bring back the old auto-routing algorithms! They replied with the following helpful advice:
Please try to download and update the charts going in Menu>>Download Maps. Try again to calculate the Route. Please check also if crossing the bridges on the base of the height in your Boat Settings. For long distances, we suggest to add an intermediate waypoint.” The last piece of adding an additional waypoint worked well for me. Solved my problem. I contacted Navionics and they replied with the following helpful advice: “Please try to download and update the charts going in Menu>>Download Maps. Try again to calculate the Route.

The last piece (adding an additional waypoint) worked well for me.
Solved my grey line problem. (Or gray line if you spell it differently in searching for this issue).
If you don't know how to add a waypoint - simply touch and hold somewhere on the grey line and drag it to a place that you think should be an intermediate waypoint along your intended route. When you let go it will recalculate the segments. It seems to do better with shorter segments.
I hope this is helpful.
