Have you tried to navigate with it? Mine works fine when stationary, it is when I actually try and use it go get somewhere that I have issues...
Yeah, I've used it a few times to get somewhere. I know that one time it told me I needed to make a u-turn and then turn right, when I really just needed to turn right. And a couple times when it said "turn right/left in X feet" I had just passed the street I needed to turn on. Neither are anything I'd consider too horrible, just time consuming if I was in a hurry. And I'm not even sure if it was the phone or GPS systems fault for the issues or what since everything else about the directions were no trouble at all.
I should also note that the Captivate is my first smartphone so I have nothing to compare the issues to.
