Friends, I am considering 2005 boats that have "Navigator II" as an included option. In my research here an elsewhere, I have struggled to crosswalk this to a user manual or feature list. On Maptech, there is Navigator I, and then there is Navigator II, and Navigator 3.5. Unfortunately, I can get user manuals for I and 3.5, but not II. The tech said, without confidence, that they are the same, but I would like to confirm this. If any of you have a 2005 Sea Ray and can provide any sort of info/review/alternative model descriptions of the unit, that would be fantastic. Do you use your Navigators, or just the Raymarine plotters sitting next to them? I would hope the unit is functional as I would like to be able to use two full screens of info, either GPS /Radar, GPS / GPS, or GPS/Camera. Thanks!
