Work out a plan with your friend. Google maps can't help you with that.
Your friend will have to go through customs, in that area it will not be possible to use the phone. It could also take an extra hour to get past US border control. Once your friend is processed you will see him and others exit from the far west exit next to baggage carousel. Starbucks is nearby. You can also buy flowers in that area or bring your own to save money.
You will have to work that out with your friend..
