We need a mapping app with -locally stored map data (Jolla's current implementation uses Here cloud and requires internet connection which makes it unfortunately almost unusable for travelers) -voice guided turn-by-turn navigation (currently there is no voice guidance which makes the app unusable or actually deadly dangerous to be used while driving) I have a bad feeling that this will not be fixed by Jolla (Jolla Maps development is outsourced).
I wonder why they went down this route for mapping in the first place. According to their interview in zdnet, they mentioned that mapping providers were aplenty and all offering similar rates so why not go full on with Nokia and ask them to licence Here Drive too like it seems will be done on tizen. As of now, the mapping application seems pretty mundane and Sygic won't work till GPS for Android apps is not enabled.
