I used google maps once on a road trip and am not sure what I did to get it to do this but I was able to get the screen to look like a 'drive mode' much like a tom tom. Don't know what happened but now I can't get that mode back as all I can get is something that looks like a map. I have to scroll with my finger while I am driving too. What did I do wrong? The 'drive mode' kept the screen lit and did not blank out but apparently it has returned to this map mode instead of a mode that really acts and looks like a useable gps.
