I'm looking forward to using Navit when it works --- looks promising, but it crashes whenever it connects to my GPS --- go figure. Would love to drop Maemo Mapper as I don't want to be connected to the internet to get routes --- you can preload before, but if you make a wrong turn, there is no way for maemo mapper to give you a new route. Navit looks like it will have onboard routing; i.e., no internet required.
