I guess bandwith costs is not their main concern. Navicore is licensicing the maps used by Wayfinder from another company. Maybe they have to pay higher licencings fees when selling a product that has complete maps preinstalled, compared to a product that is only downloding small parts of the map on demand... Overall Wayfinder is ok, but it has some annoying shortcomings. e.g. when deliberately leaving the planned route to take a shortcut, Wayfinder is sticking much longer to the old route than many other products like Tomtom. Also the user interface uhhm.. can only get better. Maemo Mapper on the other hand has some unique and very nice features (aerial photos...). But without vector maps and due to the missing ability to do route planning/rerouting without an internet connection it can hardly be called a navigation software. So I think there is definitely a market for a good and usable navigation software on the N8x0. Judging from the presentation on their webpage, this Sygic stuff looks quite promsing.
