I checked right now the homepage of Navigon. They now support the N95 with intigrated GPS sensor for there Navigation software MobileNavigator 6 Symbian S60.
The price is 99 Euro if you are downloading the software with all maps.
Please note that the size of the file you will be downloading is approximately 3,2 GB.
Text written on there hompeage:
Along with the many general innovations of the MobileNavigator 6 software, this Symbian version offers you a number of interesting extras. For example, support of integrated GPS receivers or the FriendFinder function allows you to forward your current position by SMS; the recipient can then navigate directly to you. With this feature you'll never miss each other again.
Anyone tested this software? Maybe it iis better than Nokia Maps, TomTom & Route66?
