Just got a chance to use my Magellan while I was travelling.
As opposed to my Z, I did find the announcement of street/highways quite useful as I kept my eyes on the road at all times not needing to confirm/look at what street I needed to turn.
In addition, the like the fact that magellan also advised whether to bear left on right on the interstate roads , to distinguish whether I should take the *express lanes* or * local lanes*.
The avic does doe on certain roads, but also does NOT do this on other roads...
