X5 TV hack??

Anyone know how to hack X5 4.4i so you can have the TV on when car is moving.

(I know this is stupid but its not for me, a colleague, it is so his gf can watch it, not him when he's driving)

I asked about having the factory fit tv on my M5 "hacked", apparently the cut-off is hidden in the cars software, BMW dealers used to disconnect if you signed a disclaimer, then some American crashed one and sued despite having signed one, Septics, don't you just love em...............
