2) Maemo Mapper. It's an open source map viewer. It's free. Unlike Wayfinder, it doesn't include maps. Maps have to be downloaded (from google maps or openstreetmap for example) on the go. To use it as a real navigation system, you have to be connected (through your phone) to the internet so it can download maps and routes. It is an awesome piece of software, which does good navigation and has a lot of options. If you have a good data plan on your phone, use mapper. If you don't want to rely on an internet connection, use Wayfinder. My 2cts.
