Heh, I have to say - I haven’t had issues with the nav aside from lag. There were two times I had a bad issue:
1) very early in the software, it got super confused when I was in a garage with no service and put me at Newark HQ and wouldn’t change no matter what, haha. Never happened again.
2) one time, recently, the GPS was confused and kept moving me from street to street, losing track of where the car was. Never happened again.
Directions and traffic have been spot on, though. I wonder if they’re better here in the Bay Area?
I totally believe there are more issues with the nav; the biggest for me is just lag and that I can’t adjust the volume of the voice. Glad I can at least mute it now.
