The owner's manual illustrates how to enter an address via "new destination." I find that using verbal entries I usually get cut off quickly with the irritating response "voice entry ended". Not by my choice!
Anyway, I seem to have much better success entering the address via "enter address". Now I only use Destination when I'm looking for POIs.
Have others experienced the same thing? Except for POI info, is there anything else useful about Destination?
