I expected less features and am not disatisfied with that. The manual does not give me useful information on creating routes. If what I vaugely understand is correct, I should be able to use 1 or more methods to input waypoints, then combine them to create a route. If this is the case, I could not get that definately from the manual, and think it should be the first thing mentioned. Alsok, if this is how it's done, would start and destination be sufficient or would that just point me to the destination as the bird flies.
Example, in order to navigate to Fletchers Boat House from Anacostia Boat Ramp it would take several directional changes, some of which are required only to stay in the channell. Would each chang in direction become a waypoint, or would I just need those for Anacostia and Fletchers?
