Since I have updated to 8.0 and the 810 maps, my voice input doesn't work very well. It seems the mic input isn't as loud as it used to be, so the input doesn't always hear me. It is just easier to use the keyboard now. It would be nice to have a mike level adjustment. Is this just a useless feature. It seems to me its there so you wont have to use your hands and keep your eyes on the road, but if you have to keep looking at it and saying back every time your attention is far from the road and an accident will occur from the poor voice input. Opposite of what it is intended to do. Any correction for this?
