the brother in law has just got hold of a new sportline transporter lovely bit of kit it comes with the new kenwood dnx520vbt now im appealing to the boffins out there it plays dvds but as soon as you move over about 5mph you get a blue screen now i know this is a saftey feature to stop you getting distracted whilst driving but can you over ride it as it would be well handy seeing as he has his daughter in there sometimes and trying to keep a 3 year old occupied on a journey can be tricky and a cheeky bit of shrek would help many thanks
