It might be that adding the labels of ETA and distance should be added, though we are trying to conserve information since the mobile device screen is small and too much information means that there is less place for map display. As before, I will add it to the wish list.
I am not sure I got the part about the incorrect street/turn - if there is a right turn 1 mile ahead, the only name and arrow displayed will be of the turn, not of any info before it (the streets you are passing along the way). I.e. if you are to stay on the same road, no other information will be displayed, again, because of space restraints and trying not to overcrowd the screen with information. Did I misunderstand the issue you've raised ? Can you send a link with an example ?
