TomTom One NEW Edition - help with saying street names??

Hey all, total noob here but I have tried going through all the tut's and have yet to find an answer to this.

I upgraded the navcore to 8.412.1236 and the latest 865 maps of USA and Canada. But, this particular device does not say street names. Is there any way i can upgrade that?? Try a different navcore? Different voices? Everything else works great - but rather than saying "turn left ahead" I'd love it if it would say "turn left on Main st"

Thank you for any help!

BTW: this is the TomTom One New Edition. 1gb of memory built in, no SD card expansion. Don't know if it helps...

Oh, and also - is there a way to get it to do traffic also? Or does that require a whole different machine?

(thank you, and again, I am sorry for being a noob!)

You can get computer voices or "Vocalizer TTS" working on your ONE model. Basically you need an SE navcore (which you are already using), a Vocalizer TTS computer voice that will work with your device, and you need to edit the setconfig.txt file and delete the line "ttsoff".
Here are the full instructions and download links you'll need:
