Getting road names for arduino navigation system

Is there a way for me to get road/street names from an already existing navigation system such as google maps and get it into my arduino code? Or if there is a device I can buy and connect it to the arduino? I am planning to make an arduino code that inputs gps location, finds the name of the road im on then outputs the legal speed limit in that road (ill put those in manually).
Using an arduino uno.
Any help would be greatly appreciated this is a really big university project for me!

I really can't imagine you getting much credit for doing something that commercial devices have been doing for years. My GPS shows me the name of the road I am on, and the speed limit on that road, at my current location.
