Thanks!
But - how does this the built-in map application of OS2008 ??? If i try to load the whole east Europe (apr. 130 MB - ex. Yugoslavia, Baltic and so far are poor), or Alps, then the zoom comes quick enough. Have this maps more submaps for each resolution, or may be, taht each element have as parameter a limit zoom factor ? Over this zoom factor will be then this element not displayed? And can be set up for each element separately. May be a solution for Navit maps too?

Thank you,
Feri
