When I had my verizon phone, the navigator was an extra fee (personally it sucked. i used it in a few different cities on the U740 and it gave a lot of peoplems and kept trying to locate you. Also with ATT and the BlackJack2, you had to pay for the navigator too. I am happy with free maps that shows me where I am if I get lost. Never was a big turn by turn person anyways. Also, the battery with the gps running that long with the screen on for directions would kill it so I have no use for it.
They did say that there is updates for the new firmware that is coming out that will add more features to the GPS which could possibly enable turn by turn but I doubt it.
