N95 Satelite Navigation Software

[spellcaster]

Hello,
Am i right in presuming the gps part of the phone talks to a satelite for free? What I would like to get for my N95 when it arrives is the best satnav, I have seen garmin,tomtom,nokia maps etc but I am unsure which one I can use with voice directions without being charged for the priveledge. Basically what satnav software is free to use in regards to operating costs.

I thought one of the satnav softwares has all the maps already on the phone so its not downloading them over the phone line etc? I believe one of these sat nav softwares offer the free speech too. As my phone will be pay as I go I do not want to be charged fior using the full package once i have paid for it.
