Voices without streetnames

I've noticed that the voices on my iGo Primo are voices without streetnames! Are there voices with streetnames and if s, where can i find them?

Only TTS (text-to-speech) voices are announcing street names. You need to install a TTS System which is depending on your operating system and look for TTS voices.

Thanks,

Accoridng to the information on the site of my device it supports TTS....
