Is there a Free Satellite navigation app for Blackberry 8520?

I go cycling a lot and I enjoy going on big adventures (getting my self lost). Its great and the Blackberry Maps are good to use too. However the maps only give me directions that I have to read like a map (sorry if its not explained well I don't know how to put it) I was wondering if there is a Satellite Navigation app for my phone that is FREE?|||free blackberry app for internet call, please try|||Google maps has app I guess. You can download BBmaps or TrekBuddy. They all have some limitations like taking lot of bandwidth. AccuTracking is the best software though it's not free. But you can get it for free by signing up, playing flash games, watching videos, socializing with friends, trying out new websites, and referring their friends to prizego.com
