This is what Kevin Massy wrote in hist CNET rewiew of the D3:
En route to the required destination, the Avic-D3 uses turn-by-turn voice prompts (including text-to-voice functionality) to call out turns and the names of individual roads.
I have a D3 and it does not call out the name of the individual roads. It just says left and right.
What is going on???????
