1-800-GOOG-411 + Google Mapping translated to voice might look something like this:

411: Which business or address
User: 123 Main Street, Anywhere USA
411: '123 Main Street', wait I'll connect you, you can also say 'Get Directions'...
User: Get Directions
411: Which address or city center are you at
User: 456 Center Stree, Anywhere Else, USA
411: Continue 2 miles, turn right at Smith Street...

Text messages or voicemails would work even better.
