I opened maps and opened the blue button (which is below the white button) and it opened on another page and offered "my location" and "choose location", so I put an address in "choose location" and voila, there's the keyboard.
But I noticed maps has a lot of stuff I don't need as in I don't need to know how to find the restaurant last night again... and lots of stuff like that. One thing was telling me that traffic was 12 minutes on 101 Fwy, and it offers too many places I've gone to, that I don't need a map for it. Although I can reserve dinner from the phone, but I don't really care... lots of stuff that nobody really needs except kids.
