my question is how do i get video on the front screen and control it via idrive like the EURO SPEC cars. i have the rear entertainment system and i can control the dvd/tv via rear idrive. i know the canadian & us spec cars come with this feature deactivated. any info on how to active it. the new X5's have the tv function activated for NORTH AMERICA so this feature is legal now. any help will would be greatly appreciated.
