title: File format for sending a list of addresses or coordinates to mobile phone in order to show routes through the addresses?
body: <p>I would like to send a list of addresses or coordinates to a driver in a vehicle.  The driver is using a mobile phone. (Android or iPhone).</p>
  <p>Some years ago, I believe I read that there was a file format for transferring/sending this type of information to a (Google?) app running on e.g. an Android phone.  After having received the addresses/coordinates (typically from an email), the app on the phone would show routes from A to B, and B to C, etc.</p>
  <p>Anyone having a tip on this? Any standard file format for sending this?  Any tip on a phone app that may receive and show routes through a set of stops?</p>
