Apps Turn by turn Navigation

I am trying to build an application with turn by turn navigation support. The requirement is that the app[running on an android phone] has to get the turn by turn navigation from google maps and then send this info over Bluetooth LE to a custom device. This custom device shall receive the turn turn by turn navigation information and take appropriate actions. Please let me know if this is technologically and contractually possible with google SDK to fetch turn by turn navigation info from google maps and send it across to another device?

Technically possible, yes. Can't see anything in the terms of use that prevents what you want to do, although have a good look yourself. Section 8 probably most applicable:

Although one thing that is forbidden is you charging other parties for use of the Google map data. That will get you in trouble.
