I don't have my manual handy, and I'm wondering if anyone know off hand...

 

I have my N3 set to show me multiple routes when I put in a destination. Generally there are 4-6 different routes. Does each one, or each colour represent a different method for calculating the route?

 

Like the first (red) one is just the fastest way with no special consideration (assuming that you haven't specified anything to avoid)

 

and the Second route is what you would get with the "avoid tolls" checked, and the third is with avoid freeway...and etc?

 

I just think that would be useful to know if it's the same logic every time. I know that it shows you little icons on the bottom that are supposed to represent stuff, like tolls and things, but still, if I just new that route three was avoid tolls, that would be cool.
