I also have the Nautilus & the processor just isn't as fast as the newer units. You can adjust the track up mode to only refresh when the rotation of the map is over a cert amount, degrees, (resloution angle) if you have it set to a low value it will continually keep the route dead up & constantly refresh.
See section 4.3 Map orientation in the manual.
On the route reversal are you getting the pop up screen that alerts you that the route has been reversed?
I assume you have a manual?
I am actually contemplating selling my unit as I have a Garmin 478 from work & the screen is much easier to read in the bright sunlight. I had my Sitex on my Grady which had a bimini, but my Mako CC does not & the sunlight washes it out.
I'm thinking $375 for the whole unit with a wide area chart of MA.
