I just got my X3 about 3 weeks ago.. we are planning a trip to California and I need a dvd system in my ride so my 3 yr old doesn't drive me nuts, BMW Wants almost 800 for the dvd player and 1200 for each screen. I found another company that makes DVD Systems for BMW for 1200 Dollars I get NEw Head rests with screens and a DVD UpRight Mountable dvd player with tuner and 5 video inputs a much better deal but bmw said they wont install it because its not a BMW DVD player they said that it will void the Warranty They even Said that " A non BMW Product could Fry The cars computer" I told him he's full of Sh_T but I don't want to void it... What should I do.. Can I get around this??? My dvd package is here today or tomorrow and we leave in 4 days...
