I wanted to know, if with some modification is possible to see the dvd also in the front screen. Thanks

I believe you can do that already on RR Sports with factory installed Rear Seat Entertainment system - as long as you are stationary (except in North America, where we are apparently stupid and manage to run over old ladies crossing the street even when parked!) For illegally watching movies on the front monitor while going 210 km/hr on the Autostrada Bologna-Milano however , there is a rather expensive, aftermarket module/hack available from a US company named Nav-TV (http://www.nav-tv.com/) that integrates nicely with the factory RSE . I am quite sure they have dealers in Italy as well. 

Grazie mille
