Enter the building number in the first field, using Graffiti or the on-screen keyboard. Now, switch to the second field by tapping on it. You can enter the road name either by scrolling the list and tapping the desired road, or you can enter the first few letters of the road name using Graffiti to scroll the list automatically. Note that while several roads have multiple names, they appear in the list only once. In general, the name used is the one you'd expect.
Some Manhattan roads have more than one name, but only appear once in the list.
