Just purchased Navigon and all I get when I try to route to an address is the following notification: "navigon iphone gps reception is currently not sufficient". I leave the app up for 15 minutes and that's all I get. The phone is in my car and accessible to the sky in a car mount and plugged into a power source. I even tried removing the case and still no gps signal. My 3Gs is JB if that matters.
