Voice data is voices that are used to speak turn-by-turn directions.
And based on your situation, I think the lite version is all you need.
I only got a few questions.
I live in Sweden and I allready bought MapPoint.
Do I really need to buy the version "with" Nav?
Is the nav feture available in both versions but I need to supply my one version of MapPoint in Lite Edition?
What dows "Voice Data" means is it the Voice Recogition feature och the Nav Speech Feature and does this meen that if i can use my own version of mapoint I dont get any speech?
Tx in advance
