Please e-mail your address and request in to firstname.lastname@example.org and we can send the upgrade to you. There will no be future revisions to the SeaRay Navigator software. The SeaRay Navigation systems will be manufactured and sold by a different company in the future and though the software that runs on the new system will be very similar, it will not be compatible with the existing line of Navigators.
Justine, Hi. I'm closing on an 06 Searay 44 w/ Navigator on it. I had a couple of questions. Is Navigator II and Navigator III physically different or is it just a software upgrade? Is there a place that describes the differences in the two products?
I apologize for the delay in responding. The Navigator II and III are physically different. The Navigator III has an internal power supply, an updated hard drive, USB connections vs. proprietary connections, more memory, and better reliability. Here is a link to some of the new features available with the Model 300 Navigator:
