Thread: what is basemap.fbl used for?

hi,

sorry for asking newbie questions..
1. can anybody explain what is basemap.fbl used for? is it still required to be put in the sd card in addition to, of course, the country map? seems that it's already working well without add basemap.fbl.
2. how many map/poi/dem/etc providers are there for igo primo? such as tom tom, teleatlas, naviteq? and what is comparison, and which one is the recommended one?
3. adding other country maps in the contents/map will automatically add those maps in the igo primo? And if yes, i think it will make the gps working slower , wont it?

thanks very much.
