I think a user manual would be really helpful. I can read the list of features but it is not obvious to me how everything works. I still use my Garmin GPS as main tool and only supplement it with Geooh for car navigation and descriptions because I cannot make sense of overall functionality.
Sorry for the late reply... forum notifications weren't being sent for posts.
A user manual is in the works. Until then feel free to ask questions here or via email to support@geooh.com.
