Re: How long should the negative cable be disconnected
Have only driven it for about an hour since the update but I see NO Improvement. The screen is not a "touch" screen, it's still a "touch, touch, touch" screen. Using Voice isn't any better. It did not recognize "Walmart" and there are two nearby.
Haven't tested the POI database but I'm doubtful. So far, this has been a waste of $$$ and time though being retired, I have plenty of that.
