It cannot be downloaded, it is a feature of the individual model. Think of it this way: Lower models just play pre-recorded bits - "Turn left in 50 ft", "Take exit on left in 50 ft", etc. They can't carry a recording of every street and highway name, so they just give generic directions with no proper names. The higher models have a built in text-to-speech synthesizer which read the directions from a database of text, so they can say "Turn left onto Elm St. in 50 ft", "Take Exit 5 on left to Interstate 30", etc. Without the TTS synthesizer, you can't have TTS.
