Tks for your help.
It seems like my "hopes" are going away ...

BMW does not have those maps;
Also BMW Brazil doesn't import Minis, not even VW sells Phaeton here and Rolls Royce does not have official resellers in here.
The French cars ... most of them: Renault, Peugeot and Citroen are manufacured in Brazil, and none of them has nav systems ... There are also some imported french models, BUT again with no NAV system.

Until the end of 2005, the Brazilian laws did not permit using screens of any kind in the dash of the vehicles. Last year those laws had been changed and till now we've only got some portable PDA and PND (Garmin, MIO, Delphi, etc) with Brazilian maps.

Anyway, as far as NAVTEQ has already those maps from Brazil, I guess they will soon translate them to be used in the cars !
