Yes, the 9700 has GPS. Go to Options> Advanced Options> GPS> GPS Services and toggle setting to Location ON. Now go to BB Maps, open it, hit BB Menu button and select Start GPS Navigation.
NOTE: Start GPS Navigation is ONLY available in this menu IF your GPS Location is ON!
GPS chips must be improving, I'm amazed how well it works in my 9700, and I infinitely prefer Google to BB maps. You American chappies get Google turn-by-turn free, is that right? Fantastic.
