Perhaps there is a way to enable this, but if not, it would be a feature request. I am new to MapFactor Navigator Free, but have used stand-alone GPS units as well as Google Navigator, and both announce street names, e.g. in 200 meters, turn right onto Albert street. Navigator Free says "in 200 meters, turn right". I like hearing the street name as a confirmation that I am turning onto the correct street.
I am new at using this product, but it looks very promising, and more feature rich than Google Navigator, e.g. the ability to save a location that doesn't have a formal address, also shows altitude and speed
