Haven't seen this issue posted elsewhere, wondering if it's unique.
When I first got the phone, I was driving around a lot, and of course used my nifty new phone.
The GPS would find me, find directions, and show it all in Nokia Drive, but the GPS would never update my position. Turn by turn navi obviously didn't work, because the phone seemed to think I was always at my starting position. It also occurred sometimes in the middle of following directions; that is, randomly in my trip, it just stopped following me, telling me I was 4 miles away from next turn for 20 minutes.
It occasionally corrected itself and jumped back to following me.
Anyone else?
