I've purchased a Blackberry Curve 8310 and wondered if anyone had any experience with using the GPS with Rogers in Toronto Canada? What software do you use, do you like it, is it on a card (pre-loaded) or online (downloaded each time you need a map)? I currently use the TomTom on my Treo 680 and like it, but have to switch to the Blackberry. Any idea how the GPS software compares to the TomTom?
