this is a free java based gps program that does not need an internet connection. the maps are stored on the memorystick. everything including the maps is completely free.
you can find tutorials and all downloads on the homepage:

please keep in mind that this is a work in progress and therefore it can have some bugs. i have used this on my w995 a lot of times and it never failed me
also, you don't need a gps receiver to use this. oyu can also use it to just browse the maps. and if your phone doesn't have an internal gps you can try to connect it with a bluetooth gps (supported by the program)
