Hi mate
I am also bundled with Rogers , there is no absolutely cost of using GPS . In order to view your location go to menu>tool> connectivity > GPS DATA and then open it and go to POSITION ( you have to be in open area where GPS can find satellites ) and then press OPTION > Satellites STATUS , you will see bars so you have to wait until thsese bars get darked and that means that GPS found you location and then simply go to Nokia maps and you can see your location on the map. If you didn't download Maps then go to here
http://www.smart2go.com/en/download and download Nokia MAP APPLICATION after that you have install NOKIA MAP LOADER
http://www.smart2go.com/en/help/maploader on your pc so it can transfer Canada map to your
N95(Memeory Card) .
Finally , The GPS may take 1 min-5 min to locate you location however, you can Enable A-GPS ( Assisted GPS) to get your location in 3 -10 seconds but it need internet connection so it will charge 15 cents because rogers charge 5c/kb and A-GPS transfer 3 kb-4kb so it only a small fee . If you dont know how to enable A-GPS ask me
