As the guys have said its not legal but I know the range rover has a screen which plays whilst you're driving but only the passenger can see, very clever, but the Adam sadly not but having spoken to my neighbour about this they told me they have a similar issue with their Impreza screen and found a company who disabled it, there's apparently a sensor connected to the handbrake and once disabled you can watch it not sure if this is the same on the Adam, I too thought about having it disabled so my son could watch as I drove.
