Unfortunately not understandable

I have returned the device after a single test drive back to the seller. Reason: The speech was to understand the best will hardly. The available for selection female voice sounds completely tinny and quiet. The man's voice is slightly better, but still not evident enough. It is really well equipped with tunnel assistant, speed warning and announcement of a road as a starter model, but what good is all this if you can hardly understand the driving instructions or the trendy streets?

Too bad, I would like to keep it ..... so I remain with my old Medion.
